Weiguang Han
I was looking for a gift for my wife to celebrate our 10th anniversary together, and found the entire end to end process with Novita flawless, like its diamonds. From the start, its website was intuitive to browse with many designs and options available. Appointment booking was easy, and the staff made sure to follow up closer to the date. We were served by Angeline, who patiently shared her knowledge with us on what would best fit our preferences. I would recommend Novita to anyone considering a lab-grown diamond. They offer exceptional quality, fair pricing, and a welcoming customer experience.

I had an amazing experience purchasing my engagement ring! Wendy was incredibly friendly and knowledgeable. She took the time to explain the different diamond shapes and introduced me to lab-grown diamonds, which I found really insightful. Her patience and expertise made the whole process smooth and enjoyable. The selection was fantastic, and I couldn’t be happier with THE ring. Highly recommend this store for anyone looking for quality jewellery and outstanding customer service!
Patricia Gan
A place to go if you want to get lab diamond at a decent price. I was hesitating on the design at first; oval diamond on vine design ring for extra vintage feel. Decided to go on my gut feeling and glad it turns out really nice. Yani was really patient and helpful; she gave very good advice on picking the right diamond size and clarity. I’m very happy with the purchase, and my gal pals are now tempted to get one for themselves, too!

Jianrong Tan
Had a great experience with William for our engagement ring. He spent more than an hour explaining about natural vs lab diamonds and their specs, showed us the stones under different lighting and entertained my 10000 questions about the stone and ring designs in person and over WhatsApp. Designer Ming also chipped in with her suggestions for the ring design which I appreciated and incorporated as well! She presented me 2 designs which i love, hence in the end I decided on one for my engagement ring and cant wait to use the other design for my wedding band with jann Paul as well! Thank you both!
Rei Ting Quah
Back in early 2024 I started shopping for my engagement ring, and I knew from the start that I wanted a lab diamond – less costly without compromising much on carat wt. There were quite a few options in Singapore but none really stood out to me until I saw a JannPaul ad on my feed (thank you algorithm gods). I fell in love instantly. I made an appointment specifically with Avery based on the many great reviews she already had, and the experience was so fun and insightful. She took the time to not only explain the 4Cs and the differences between lab and natural diamonds, she also showed us how their diamond cuts are better using all the very professional inspection tools. We even stepped outside the store in the sunlight to see how much more their diamonds sparkled in comparison. I felt like I was at a tedtalk on diamonds and I loved it. There was also zero hardsell, zero pushiness to get you to decide asap or purchase more. Talking to Avery made me feel like I was shopping with a friend who had my best interests at heart, especially when I wanted to go up in carat wt. and she advised against it as it wouldn’t complement the whole look of the ring. And she was right. We ended up getting our wedding bands from JP too and have absolutely no regrets. Fast forward to late 2025, it’s only natural that I come back to Avery and JP for my wedding jewellery and I can’t wait to see their amazing work come to life again 🙂 I wholeheartedly recommend Avery and JannPaul for couples looking for not only unrivalled sparkle in their wedding rings, but also a truly lovely and memorable shopping experience for such a major life milestone. Thank you again Avery for making this journey so special for us!

Got my engagement ring here. Very efficient service, got the custom made ring in a month. Quality is top notch and with a good price. But most importantly my service personnel Geraldine gave me a wonderful customer experience, ensuring I got the perfect ring for my partner, from the color to the size, she patiently explained to me in detail about the quality of the ring and its value and show live comparison with the normal rings from outside sellers. If you want a trustworthy ring and most importantly a seller that cares, this is the place to go. Definetly there will be future purchases.

Nur Aryati Khairullah
Lost my wedding ring 7 years ago and never got around to getting a replacement as my trust issues held me back from imparting my hard-earned money to just any vendor… until Carat Heritage came (I never thought i’d get a lab-grown diamond) and I have absolutely no regrets! Ashley’s customer service was amazing, meticulous, honest, patient, professional and such a joy to work with that i am all smiles now just by thinking back on all that. She not only helped replicated my lost wedding ring but my new ring came out much more stunning that I am absolutely in love with it (albeit sayang to wear because it’s just so sooooo beautiful!). Quality’s impressive with attention to detail, sparkling shine and luxurious packaging. Worth every single penny and highly recommend Carat Heritage!
Jonas Sng
I had an exceptional experience at Carat Heritage. Belle was incredibly knowledgeable and took the time to understand exactly what I was looking for. Her expert advice and product knowledge made the entire selection process seamless and enjoyable. I truly appreciated her genuine care and attention to detail — it never felt rushed or sales-driven. The craftsmanship of the piece I purchased was nothing short of outstanding. You can really see the dedication and precision that goes into their work. From start to finish, the service was impeccable and the quality truly speaks for itself. If you’re looking for fine jewelry with both elegance and substance, paired with sincere, professional service — Carat Heritage is the place to go. Highly recommended!

Customer Reviews:
Kit Chua
Was looking for a jeweller to make a custom designed ring with and chose Lecaine for the quality of their lab-grown diamonds and the design sensibilities showcased in their store. The process was very enjoyable throughout, the team at Lecaine are so positive in their communications and really a pleasure to have worked with. When my ring was ready, they even hand delivered it to me while I was in confinement! And finally the ring itself turned out so beautifully – the workmanship of the setting is well crafted and the brilliant cut diamond I chose looks absolutely flawless.
eulanie Madrid
The ring is absolutely gorgeous! Everything I wanted! My Customised round Moissanite looks very sexy and super elegant. Ashley is very accommodating in every way. I also ask them to clean my old sapphire jewellery, I’m very delighted with the result it looks new now, everything is worth every penny. Thank you LeCaine!
J G
This is my second time customising a ring with LeCaine Gems, the first being a moisssanite ring. They did such a good job with the first that this time I trusted them with my 10th year wedding anniversary ring. I have customised several rings with other jewellers before and have experience and high standards. No one comes close to LeCaine. From sourcing the perfect oval blue sapphire, bringing my desired design to life and the friendly communication throughout, you can trust Ashley, Michael and team to deliver on every detail. And within budget. The result is stunning and will be an heirloom forever.

I was chilling one day and my Queen saw the Rio Diamonds wedding band rings on sales so she made an arrangement to head down after our trip. We were served by Yu Fei who were professional and takes pride in her work. She provided us a lot of advice and helped us through our journey in securing our wedding bands. Can’t wait to receive it in 2-3 months and start admiring them.

Justin Tin
Heard of many good reviews of Vivo Diamonds, hence decided to purchase my proposal ring there. Indeed, the staff was very friendly, helpful and managed to provide me many great insights about choosing the right one. I am very satisfied with the diamond as it really came with good quality and the price was reasonable. Will definitely get my wedding bands from there too.
R S
1. Wide selection of designs and ideas in store. SO liked two designs so we ended up getting a half and half custom design, which Vivo was able to organise.
2. Fair pricing – Vivo price matched an external diamond ring quote we sourced ourselves.
3. Great service attitude – They carry (or can source) the full range from moissanite to lab grown to natural. Figure out what you want / your budget and they will fit it. Absolutely no pressure / upsell, just a free and easy chat, and an open invitation to contact them by WhatsApp thereafter.
Spoilt for choice at a fair / competitive price, with a obligation-free smile. Perfect experience. Definitely worth a visit – plan early!
Ignacio
Best service I’ve received in Singapore in a jewelry store (or in general), super friendly and knowledgeable staff. Moreover, they have a large variety of rings for different budgets and preferences. I bought my wife’s proposal ring with them and we came back to buy our wedding bands. Very happy with the entire process including the end result.

BestLah’s Recommendation
You’ve seen the top jewellers for lab-grown diamonds in Singapore, now it’s about choosing the right fit. Whether you’re after expert showroom guidance, custom design, or a Valentine’s Day gift with meaning, these three recommendations point you in the right direction.
1. If You Want A Thoughtful Valentine’s Gift That Feels Personal
Our pick: Carat Heritage
Carat Heritage is our top recommendation for Valentine’s Day gifting because it blends romantic craftsmanship with personalised attention – exactly what you want for a meaningful present. Unlike mass-produced pieces, Carat Heritage handpicks each lab-grown diamond based not just on the 4Cs but also on character, ensuring every stone has its own personality and presence.
With durable 18k solid gold settings, a lifetime warranty that includes resizing and repairs, and an emphasis on thoughtful, one-on-one service, Carat Heritage makes the shopping process feel intimate and special, perfect for Valentine’s Day. Their designers work closely with you to translate your ideas into a piece that reflects your partner’s style and your unique story, whether that’s a timeless solitaire, a sparkling trilogy ring, or a custom design with sentimental motifs.
2. If You Want Hands-On Viewing And The Most “No-Regret” Experience
Our Pick: Novita Diamonds
Novita Diamonds is the safest choice if you want to see what you’re buying before committing. With 400+ lab-grown diamonds available in their showroom, you’re not limited to a handful of “sample stones”, you can compare different shapes, sizes, and sparkle styles in person and choose what genuinely looks best on your hand. Their diamonds are also graded by multiple gemmologists, which adds extra reassurance if you’re not confident assessing clarity or cut yourself.
What makes Novita especially strong for first-time buyers is the post-purchase support: free resizing, lifetime cleaning, and a 30-day easy return policy. For engagement rings or milestone gifts, that combination of in-person certainty + safety net is exactly what reduces buyer anxiety.
3. If You Want A Truly Custom Ring With Cut Quality You Can Feel Confident About
Our Pick: JannPaul Diamonds
JannPaul is the go-to when you want a ring that feels intentionally crafted, not “off the shelf”. They’re especially strong for engagement or proposal rings because they don’t just sell you a diamond, they guide you through why certain stones look brighter and cleaner under different lighting. Their focus on precision craftsmanship and strict diamond certification gives you more confidence that you’re paying for sparkle and performance, not just carat weight.
They’re also a great option if you have a specific vision (a particular setting style, proportions, or design references) because their bespoke process is structured and consultative. If you’re the type who wants to understand the details and walk away feeling like you made an informed, high-quality choice, JannPaul is the strongest fit.
Final Thoughts
Lab-grown diamonds in Singapore now offer a brilliant, sustainable, and accessible alternative to traditional mined diamonds. From precision craftsmanship and ethical sourcing to bespoke design and exceptional service, these ten jewellers represent the best of the city’s sparkling scene. Whether you’re hunting for a classic solitaire, a colourful fancy diamond, or a fully custom engagement ring, you’re sure to find the perfect piece that aligns with your style and values.
For those who lean toward the timeless elegance of gold, there are just as many jewellers offering impressive selections of wedding gold rings in Singapore that rival any diamond in beauty and craftsmanship. From bespoke creations to ready-to-wear collections, the options are as dazzling as they are meaningful, ensuring your special day is marked with jewellery that lasts a lifetime.
Frequently Asked Questions (FAQ)
2. How much can I really save compared to natural diamonds in SG?
The price gap has widened significantly. In 2026, you can expect to pay roughly 60% to 80% less for a lab-grown diamond compared to a natural one of the same 4Cs (Cut, Color, Clarity, and Carat).
Example: While a high-quality 1-carat natural diamond might cost you upwards of $8,000, a lab-grown equivalent could sit comfortably around $1,500 to $2,000, allowing you to "upgrade" to a much larger stone or a more elaborate setting without blowing your BTO renovation budget.
3. Will it pass a diamond tester at a local jeweler or pawn shop?
Yes, it will. Since lab-grown diamonds have the same thermal and electrical conductivity as natural diamonds, standard handheld diamond testers used by local shops will identify them as "Diamond."
To tell the difference, a jeweler would need specialised, highly expensive equipment that detects minute growth patterns.
4. Do lab-grown diamonds have any resale value in Singapore?
This is a point for candor: the resale value is currently low. While natural diamonds typically retain about 30–50% of their value, lab-grown diamonds are often viewed more like high-end electronics than "investments."
Most traditional pawn shops or second-hand dealers in Singapore may offer very little for them, or may not buy them back at all. Buy a lab-grown diamond for its beauty and sentimental value, not as a financial asset.
5. Are they accepted for traditional customs like Guo Da Li?
Traditional Chinese betrothal customs (Guo Da Li) usually prioritise 999 Gold (Si Dian Jin) because gold is a historical store of value. However, modern Singaporean couples increasingly include the engagement ring in the ceremony.
While older generations may still prefer the "rarity" of natural stones, the acceptance of lab-grown diamonds is growing rapidly among younger families who value transparency and practical spending.
6. Which certification should I look for: GIA or IGI?
In Singapore, both are respected.
- IGI (International Gemological Institute): Historically the leader in lab-grown certification; they provide very detailed grading.
- GIA (Gemological Institute of America): The "gold standard" of grading. Since 2020, they have offered full digital grading reports for lab-grown stones.
- Tip: Always ensure the report number is laser-inscribed on the diamond’s girdle (visible under a loupe) to verify it matches the certificate.
7. Do they turn "cloudy" or yellow over time in Singapore’s humidity?
Not at all. Because they are chemically identical to natural diamonds, they will never change color, lose their "fire," or become cloudy. Any "cloudiness" you see after a few months of wear is usually just a buildup of lotion, sweat, or oil—common in our humid climate. A quick soak in warm soapy water and a soft toothbrush will bring back the original sparkle.
8. Can I get a lab-grown diamond ring insured?
Yes. Most major insurers in Singapore that offer "Valuable Items" or "Personal Assets" coverage will insure lab-grown diamond rings. You will simply need to provide the purchase receipt and the grading certificate (GIA/IGI). The premiums are generally lower because the replacement cost is lower than that of a natural stone.
9. Is there GST if I buy a lab-grown diamond online from overseas?
Yes. If you order from an international website and the total value (including shipping) exceeds S$400, you will be required to pay 9% GST (the current rate as of 2026) upon the item’s arrival in Singapore.
Buying from a local GST-registered jeweler usually means the 9% is already included in the displayed price, which can sometimes be more convenient than dealing with customs.
10. Why are so many couples switching to lab-grown in 2026?
The shift is driven by a mix of ethics and economics. Many Singaporeans now prioritise "conflict-free" origins and lower environmental impact. Additionally, with the rising cost of living, couples are choosing to spend less on the "rock" and more on the wedding experience, a house, or a lavish honeymoon—all while still getting a ring that looks spectacular.
