Let customers speak for us
Bought this pair of ear studs as a Mother's Day gift and she really loves it! It's chic and not too flashy so she feels comfortable wearing it regularly- but also classy and shiny enough for her to transition to an evening out for a nice dinner!
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!
The experience was incredible from start to finish. Ashley was super friendly, patient, and genuinely helpful throughout the process. She made what could have been a stressful decision feel easy and enjoyable.
The ring itself is absolutely stunning, beautifully crafted, perfectly sized. It felt personal and meaningful.
I can’t recommend them enough not just for the quality of the ring, but for the outstanding service.
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!
In love with how it catches the light and brightens up the whole look. Can’t go wrong with these. Prompt and great service from Ashley. All in, a very pleasant experience
Went several local jewellery shops to hunt for an ideal engagement ring and the designs are either not to my liking or the price is above my budget. Eventually, my fiancé and I are happy to found Carat Heritage who managed to customised a piece which we absolutely adore.
Belle and Ashley were very patient with our enquiries, made the effort to show us some of their pieces before we confirm on the order. Would definitely recommend them to my friends who are getting married or anyone who wish to add another fine piece of jewellery to their collection (at a reasonable price!)
Although they look dainty and delicate, the sparkle is still amazing. Had it for over 2 weeks now and it does well without having to take them off for showers and such. Happy with my new good luck charm!
Initially wanted a round 3 carat eternity ring, but so glad I sprung for this design instead. The oval and emerald mix is really unique and I've received many compliments on my new ring. It's strong and sends a confident message when I wear it to work :)
Seen a few such designs around and finally found the one that ticks all the boxes. Large enough to sparkle and delicate enough for everyday wear. Love how they look on my ears, thank you!
I just got my first ever piece of lab-grown diamond jewelry and I’m totally in love! It’s so pretty and has already become part of my everyday look.
I found out about this brand through a friend’s recommendation, and I’m really glad I did. The quality is amazing! The diamond sparkles beautifully and the whole piece feels super well-made. The sales assistant was also really helpful and knew a lot about the different cuts and designs, which made choosing so much easier.
I’m already thinking about expanding my collection with more pieces from here! I might even consider trying out their customisation service next
I recently purchased the Colette Solitaire 2-carat diamond ring on behalf of my son, and I must say it has been an exceptional experience from start to finish. The name Colette, meaning "victorious" and "refined," truly reflects the timeless elegance of this ring. Crafted in 18k white gold, its classic evergreen design is simply stunning and sophisticated yet understated, making it a perfect symbol of enduring love. It is undeniably excellent value for money.
The ring was presented as a surprise to my future daughter-in-law on the day of her engagement to my son, and it added a memorable touch of joy and emotion to the occasion. The sparkle in her eyes upon receiving it said it all.
I would especially like to thank Ashley for her outstanding and personalised service. She went above and beyond, not only assisting me with the purchase, but also taking the time to personally meet my future daughter-in-law to ensure the ring was the perfect size. Her professionalism, warmth, and attention to detail were truly impressive. The ring was even delivered directly to my home, making the process seamless and stress-free.
As someone who believes strongly in sustainability and protecting our ecosystem, I deeply appreciate that this is a lab-grown diamond. It aligns perfectly with my values, preserving nature and respecting its balance. I’m proud to have chosen a piece that is both ethically sourced and environmentally responsible.
This purchase has been a rewarding experience in every way, and I wholeheartedly recommend both the CARAT Heritage and the team behind it.
Absolutely thrilled with my purchase! I decided to treat myself to these diamond earrings to replace my cheap cubic zirconias, and I couldn't be happier. The diamonds are incredibly sparkly and catch the light beautifully! I also really appreciate how secure the stoppers are so I never have to worry about losing them. These earrings are the perfect blend of elegance and peace of mind. Highly recommend!
This is my 3rd tennis bracelet and I couldn’t resist the attractive price during their Mother’s Day sales. The quality is surprisingly great and very comparable to the other two I bought from luxury stores. Love the purchase and thank you for answering all my questions! 😁
Love the sparkle on this pair! I had other solitaire studs which were harder to wear daily especially when sleeping. These studs have a nicely designed secure backing but they are so comfy.
Having toiled all these years, I rewarded myself with a big solitaire on my xxth birthday but ouch, how expensive at $xx,xxx!
Bye bye expensive diamonds... no more 5 figure spending!
I am soooo pleased with my solitaire ear studs from Carat Heritage ... Diamonds are women's best friend and so are you, Ashley! You are superbly patient, know your customers and have a good eye!
