Customer Reviews:
Arthur Teng
Highly recommended if you are looking for expert and personalised advice on diamonds. Their website had caught my eye initially as they were very educational. During the actual viewing, George was also keen to share and advised me on which diamond to choose based on my budget. Very happy with the final product and will return for sure. Fully trusted professional in anything diamond related.
MA GON
Buying diamonds on the go in a shopping mall is like marrying a first met stranger in the MRT. Everybody knows, it takes careful consideration, grooming, lust, long term vision, feeling of uniqueness. And it all starts with that spark at the first sight. The same qualities apply for choosing diamonds. If you have someone unique like that in your life, then the best way to appreciate it, is to offer her carefully selected diamonds from George. That initial spark will be engraved in the never ending aurora or light. Very happy client of 2ct diamond stunning earrings.
Jing Yuan
One of the best place to go for that customized diamond ring and ideal setting. George shared what to look out for in a diamond (specwise) while Jolene helped me choose the one based on my affordability. 1 trick is to browse their online diamond catalogue and choose the one you like according to your budget before going down to seek their opinion. For me, I saved 400sgd after Jolene managed to find another similar spec diamond during the consultation. Overall experience was impeccable and it helped make the wedding engagement process planning more bearable..

Andy N
Amanda provided a very comprehensive overview of diamond selection and helped in picking a nice ring.
Melody Chin
My engagement ring came from e-clarity more than 12 years ago. The owner, Amanda, is very passionate about what she does and has deep knowledge on diamonds. The service from her and her team has always been personalised and warm. 12 years later, I’m still loving the unique setting of my ring. In addition, the post-sales service has been fuss-free and accessible.
Deborah Fong
My husband and I made our wedding + engagement rings with Clarity and it was a great experience, and I ended up renting a pair of beautiful solitaire diamonds for my actual day wedding as well. Amanda and the team have been so accommodating, friendly and kind – even giving us a free extension of the rental period so I could pick up the earrings a little earlier to reduce hassle on the wedding day itself.

Jia Hui Wong
I bought 2 beautiful jade pieces as si dian jin from Carat 55 and was impressed with their good service and professionalism. I could customise the design, and Zoie was friendly, attentive and responsive throughout the entire process. I received the jewellery within the promised timeframe as well. Keep up the good work and thank you Carat 55!
Matthew Jeremiah Koh
Sourced for an engagement ring at multiple places and I had the most pleasant experience with Carat55! Zoie was very personable, patient, and professional. Not for a moment do I feel like she’s giving a sales pitch. As a result, I made up my mind easily and made the purchase within an hour. I was well-informed and very satisfied with my purchase! My fiancée loves the elegance of the ring setting and the cut of the diamond as well. If there’s one thing I hope for on top of their already good customer service, the WhatsApp replies can be more prompt for customer queries.

Frequently Asked Questions (FAQ)
2. When purchasing a 1-carat diamond in Singapore, which of the 4 Cs (Cut, Colour, Clarity, Carat) should I prioritise to ensure maximum brilliance and visual impact?
For a 1-carat diamond, the single most important factor to prioritise is Cut.
- Cut over Clarity/Colour: A diamond's cut determines how effectively light enters and reflects out of the stone. An Excellent or Ideal cut will make a diamond with slightly lower Colour (e.g., I) or Clarity (e.g., SI1) sparkle brilliantly, often masking minor imperfections or a faint tint. A poorly cut diamond, even a D colour, VVS1 clarity stone, will look dark and lifeless.
- Balancing the Cs: A practical approach for Singaporean buyers looking for the best visual value is to target:
- Cut: Excellent/Ideal.
- Carat: Exactly 1.00 ct.
- Colour: G to I (Near Colourless).
- Clarity: VS2 to SI1 (Eye Clean).
This combination provides a stunning, high-brilliance stone without the premium price associated with flawless, colourless diamonds, allowing you to allocate budget to a better setting or a slightly larger diamond.
3. Are lab-grown 1-carat diamonds a popular and value-for-money choice in the Singapore market, and how do they compare in terms of certification?
Yes, lab-grown 1-carat diamonds have rapidly gained popularity in Singapore, particularly among younger couples, due to their exceptional value proposition.
- Value for Money: Lab-grown diamonds offer the exact same optical, chemical, and physical properties as mined diamonds but are typically 40% to 70% less expensive. This allows consumers to purchase a significantly larger or higher-quality 1-carat stone (e.g., a Colourless D/VVS1 instead of a Near Colourless G/VS2 natural diamond) for the same budget.
- Certification: High-quality 1-carat lab-grown diamonds are certified by reputable, independent gemological laboratories such as the International Gemological Institute (IGI) or the Gemological Science International (GSI). Like GIA for natural diamonds, these reports detail the 4 Cs, ensuring transparency and quality assurance for the Singaporean buyer.
4. How large does a 1-carat round brilliant diamond actually appear on an average finger, and what ring setting can be used to visually enhance its size?
While "1-carat" refers to weight (0.2 grams), a standard 1-carat round brilliant diamond has a diameter of approximately 6.4 to 6.5 millimetres (mm). This size is generally considered a significant, noticeable, and classic size on a typical Singaporean finger.
To visually enhance the diamond's apparent size, consider these popular settings:
- Thin Pave Band: A slender band makes the 6.5mm diamond appear disproportionately large. When the band is lined with tiny pave-set diamonds, it adds overall sparkle and draws attention solely to the centre stone.
- Prong Setting (Six or Eight Prongs): Minimal metal obscuring the stone allows for maximum light entry and exit. A simple solitaire setting with a delicate basket will lift the stone and let its full diameter be visible.
- Halo Setting (The "Double Carat" Look): This setting surrounds the 1-carat centre stone with a ring of smaller diamonds. This can dramatically increase the overall diameter and brilliance of the ring, often giving the impression of a much larger 1.5 or 2-carat stone.
5. What are the essential certifications Singaporean buyers should insist on for a 1-carat natural diamond, and why are they so crucial?
For a 1-carat natural diamond, Singaporean buyers should primarily insist on a grading report from the Gemological Institute of America (GIA).
- The GIA Standard: GIA is the most respected and authoritative grading laboratory globally. Its standards are internationally recognised and considered the benchmark for diamond quality. A GIA report provides an objective, unbiased assessment of the diamond's 4 Cs (Cut, Colour, Clarity, Carat).
- Cruciality in Singapore: Given the significant investment of a 1-carat diamond, the GIA certificate acts as the definitive proof of its quality and value, essential for:
- Verification: Confirming you are receiving the exact stone you paid for (GIA diamonds are often laser-inscribed with their report number on the girdle).
- Valuation: The certificate is necessary for accurate insurance and potential future valuation.
- Comparability: It allows for transparent price comparison across different jewellers, ensuring a fair purchase.
6. With Singapore's humidity and active lifestyle, what is the best way to maintain and clean a 1-carat diamond ring to keep it sparkling year-round?
Singapore's humid climate and the use of hand creams/sanitisers can cause oils and dirt to rapidly dull a diamond's surface. Proper maintenance is essential to preserve the brilliance of a 1-carat stone.
- Regular Home Cleaning (Weekly/Bi-weekly):
- Soak the ring in a solution of warm water and a mild, non-detergent dish soap for about 20 to 40 minutes.
- Gently scrub the diamond (especially the underside, which traps oil) and the setting with a soft-bristle toothbrush (like a baby toothbrush).
- Rinse the ring thoroughly under warm running water. Crucially, ensure the drain is covered.
- Pat it dry with a lint-free cloth. Avoid using paper towels, which can scratch the metal.
- Professional Cleaning (Every 6-12 Months): Have your ring professionally checked, cleaned, and polished by a jeweller. They use ultrasonic cleaners which safely remove deep-set dirt and check the integrity of the prongs, a vital step to prevent the 1-carat stone from becoming loose or falling out.
7. What is the typical process and timeline for custom-designing a 1-carat diamond engagement ring from scratch in Singapore?
The customisation process for a 1-carat diamond ring in Singapore generally takes between 4 to 8 weeks, though some complex designs may take longer.
The process typically involves these steps:
- Diamond Sourcing (1-2 Weeks): You select the perfect 1-carat certified diamond based on your 4 Cs preferences and budget. This is the foundation of the ring.
- Design Consultation & CAD (1-2 Weeks): You work with a designer to create a sketch, choose the setting style, and finalise the metal (e.g., Platinum, 18K White/Rose Gold). The jeweller then creates a Computer-Aided Design (CAD) rendering for your approval, providing a highly realistic 3D image.
- Casting, Setting, and Finishing (2-4 Weeks): Once the CAD is approved, the jeweller casts the setting in your chosen metal, carefully sets the 1-carat diamond, and performs the final polishing and finishing. A final quality check ensures the prongs are secure and the ring is flawless before handover.
8. How does the choice of metal (Platinum vs. Gold) for the band affect the appearance and long-term durability of a 1-carat diamond ring in Singapore?
The metal choice affects both the aesthetic of the 1-carat diamond and the ring's longevity.
| Metal Type | Appearance & Maintenance | Durability & SG Consideration |
|---|---|---|
| Platinum | Naturally white and will not fade or change colour. It offers the best contrast, making the 1-carat stone look brighter and whiter. | Highly durable and hypoallergenic. It is heavier and scratches less; instead of wearing away, it develops a patina. It requires minimal re-plating, making it a low-maintenance choice for daily wear. |
| 18K White Gold | Is an alloy of pure gold mixed with white metals and coated in Rhodium (a bright white metal) to give it a bright finish. | Very strong, but the Rhodium plating wears off over time, revealing a slight yellowish tint. It requires re-plating every 1-2 years to maintain its bright white look, which is an additional, recurring cost. |
| 18K Yellow/Rose Gold | Offers a traditional or romantic, warm contrast. Yellow gold can make a slightly lower-coloured (J, K) diamond appear whiter by contrast, while Rose Gold is currently a popular fashion choice. | Very durable, but the colour is permanent. Rose gold is slightly stronger than yellow gold due to its copper content. Neither requires Rhodium plating. |
9. Is a 1-carat diamond ring considered a good investment, or should buyers view it purely as a sentimental and luxury purchase?
For most Singaporean consumers, a 1-carat diamond ring should be viewed primarily as a sentimental and luxury purchase, rather than a financial investment.
- The Investment Reality: While diamonds are a valuable commodity, their retail price includes significant markups (design, marketing, setting, labour). The price you pay is much higher than the secondary market or wholesale value. Unless the diamond is a rare, fancy coloured, or exceptionally large stone, it is unlikely to appreciate in value to match the initial retail cost.
- Focus on Sentimental Value: The true value of a 1-carat diamond engagement ring lies in its emotional significance and lasting quality. Choosing a high-quality stone and a durable setting ensures it will remain a sparkling heirloom for generations, which is the ultimate return on investment for an engagement ring.
10. How does diamond fluorescence affect the appearance and pricing of a 1-carat diamond, and should I avoid stones with strong fluorescence?
Fluorescence is a grading that describes a diamond's tendency to glow blue (most common) or another colour when exposed to ultraviolet (UV) light. It is graded by GIA as None, Faint, Medium, or Strong.
- Appearance (The Exception): For most high-quality 1-carat diamonds (D to H colour), fluorescence (even Medium or Strong) has no visible effect on the diamond's sparkle or colour under normal lighting conditions.
- The Rare Exception (The Rule of Thumb): In rare cases, usually with diamonds of a high colour grade (D, E, F), Strong or Very Strong Blue fluorescence can cause the diamond to look slightly milky or hazy. This is why this grading is often viewed with caution.
- Pricing Impact: Due to the historical stigma and potential for haziness, 1-carat diamonds with Medium or Strong fluorescence are often sold at a 5% to 15% discount compared to stones with None or Faint fluorescence. Singaporean buyers can take advantage of this by confidently choosing a Medium Blue fluorescent stone in the G-I colour range, as it typically offers the same beauty at a better price point, often without any adverse visual effects.
