Frequently Asked Questions
- Wrap a thin strip of paper or string around the base of your finger. Mark where it overlaps and measure the length with a ruler in millimeters and check it against the ring sizing chart.
- Measure the inside diameter of your existing rings (the distance across the center of the ring) with a ruler and check it against the ring sizing chart.
- Order a ring sizer from us.
Tips for Accurate Measurement
Measure at the end of the day when your fingers are at their largest.
Avoid measuring when your hands are too cold or too warm, as temperatures can affect finger size.
Ensure the ring is snug but comfortable—it should slide over your knuckle without being too loose.
Diamond carat sizes varies widely depending on an individual's lifestyle, personal taste and expected usage of the ring. Many people typically purchase 1.5 - 2.5 carats for an engagement ring and we can guide you on the best size for your needs.
Our diamonds are sourced with the strictest quality standards, handpicked by our experts, who examine each stone with their own eyes. Some key differentiating factors include:
- IGI certified CVD stones
- Made with 100% pure carbon, no nitrogen
- No BMG ( "Brown, Green, or Milky" - refers to a diamond's background hue or shade)
- No bluish or greyish tones or lines
- Highest possible sparkle or lustre, which is a diamond quality not captured within the 4 Cs of diamond certification
Yes, we have various diamond ring designs available for private viewing appointments at our Centrepoint showroom. Please contact us to discuss availability.
We can craft our jewelry in both lab diamonds and mined diamonds.
Do note that chemically, physically, and optically, lab grown diamonds are identical to mined diamonds. They're real diamonds with the same crystal structure and beautiful sparkle as natural diamonds. Lab grown diamonds also have the same famous Mohs hardness of 10. They're just as durable as natural diamonds and indistinguishable (even by gemologists) without reading their inscriptions.
Whether you prefer a lab or mined diamond, we can source and craft with both.
We offer lifetime resizing, repairs and adjustments if you purchase one of our products.

The team at Carat were fantastic to work with and so helpful. I had a bit of a unique situation & a fairly tight timeframe, but their communications were excellent and we got everything organised in time! The ring itself is absolutely stunning - exactly as expected, beautifully made and with a gorgeous sparkle. My partner (now fiancée) is thrilled with it.
Fell in love with this ring at first sight and the symbolism solidified our decision. We cant be happier with our choice. Thank you Carat Heritage for helping us create such a beautiful engagement ring within our timeline and budget!
Extremely happy with the ring and the diamond
Recently purchased a Vita Oval 3-carat diamond ring from Carat Heritage, and I couldn’t be happier with the entire experience. The service was exceptional from start to finish—professional, attentive, and truly customer-focused.
The ring itself is absolutely stunning. The diamond shines brilliantly, the craftsmanship is excellent, and the overall quality exceeded my expectations. It feels luxurious yet still great value for money, which makes the purchase even more satisfying.
My wife loves the ring, and seeing her so happy makes this buy incredibly special. I highly recommend Carat Heritage to anyone looking for beautiful jewellery and trustworthy service. We will be back!
The service from Ashley was extremely personal and the ring I received, just beautifully perfect. The cherry on top is receiving it way ahead of time (almost 3 weeks early). I cannot recommend Carat Heritage enough. I will be going back for the wedding bands for sure. Thank you!
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!
Sparkles brilliantly, feels light on the finger, and priced just right.
Love the pinky ring!! Have been wearing it ever since I got it in Feb and it’s still super sparkly - got many praises too! Will purchase again
Compared Carat Heritage with a few other lab diamond brands around Singapore and felt their craftsmanship looked more refined. The prongs and finishing were done nicely.
Customised an emerald-cut engagement ring and I still catch myself staring at it sometimes 😅 The clean lines and sparkle are beautiful. We viewed emeralds at many places but the ones at Carat Heritage really outshone the rest. We are really glad we decided to go with Carat Heritage.
I purchased the Veda ring for my birthday and couldn't be happier. The oval diamond looks larger than I expected and has incredible sparkle. It's elegant without being too flashy.
DAWNNA WAS WELCOMING & FRIENDLY. ELOQUENT IN ENGLISH, SHE IS ABLE TO ASSIST US. SHE CATERED TO OUR NEEDS REALLY WELL AND WAS PATIENT WITH US.
The ring is beautiful
Had a great experience purchasing an engagement ring from Carat Heritage. Ashley was very patient with showcasing and explaining the different rings and their unique features at their showroom. The diamonds are also of great value and quality compared to its competitors. Will highly recommend Carat Heritage to anyone looking for a high quality ring or diamond!
The online photos are accurate, which was a relief because I bought without visiting the showroom first. Ring arrived looking exactly like what I ordered.

Friendly knowledgeable staff. I ordered a bespoke ring so it took a little longer, but well worth the wait. Very reasonably priced.
Good balance between quality and affordability. You can tell they focus more on clean, timeless styles rather than overly complicated designs.
Walked into the showroom just to browse but got drawn to a pear-shaped ring. The setting was delicate and didn’t feel bulky like some other brands. Service was friendly, not intimidating.
I got the oval solitaire ring with a hidden halo and I’m honestly very happy with it. The sparkle is beautiful, especially under natural light. Only small thing is I wish there were more ready sizes available in-store, but Ashley at the Centrepoint showroom was super helpful in arranging resizing.
I was introduced to Ashley (Carat Heritage) from a friend. Ive got nothing but great things to say about their product and their service. Gave her a budget range to work with and the type of ring that my fiance wants. Needless to say - she delivered.
She understood the diff culture appropriations - for a malay wedding, even she advised (taught) me to check on something i wasnt aware of 😂😌
More so, im currently based out of Singapore and its definitely easy to work with her given the distance and my bank arrangements due to my recent allocation. There were certain info she needed that i couldn't give her on time - but she chased me diligently which i appreciated especially complementing my work schedule.
Paid as much for the ring as i did for the service. Would recommend for anyone!
Love the minimalist aesthetic of their jewelry. I got a marquise-cut ring and it looks elegant without being too trendy.
I had a very good experience with Carat Heritage, great and professional assistance, prompt updates and follow-ups throughout the whole process and the final ring looks amazing!
Honestly didn’t know much about diamonds before coming here. The staff explained everything in a very beginner-friendly way. Left feeling much more confident about the purchase.
The showroom is smaller than I expected, but the pieces are well presented and easy to try on. Ashley was friendly and knowledgeable throughout.
Beautiful jewellery and excellent service. Thank you so much for your quality assurance and assistance. 🙏🙏
The team at Carat were really helpful with a short turnaround. I proposed with the Véda Ring and received an immediate "yes." 🥰 The ring looks timeless and the craftsmanship is excellent.
Very happy with my gorgeous ring! Great service and quality!!!!
