![[Pre-order] Joy 3.00 ct. Solitaire Ear Studs (6.00 ctw)](https://judgeme.imgix.net/carat-heritage/1769473448__1769473440133-img_6891__original.jpeg?auto=format&w=480)
Thankful to have Ashley to help me out with all my questions, make the transaction fast and easy. Super in love with my solitaire ear studs, would definitely get my next jewelry from them.
Excellent service and responsive with good knowledge on jewellery . Gave great gift advice also for first time buyers .
Prices are highly comparable and competitive . Products are simple , classy and elegant
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!
I was pleasantly surprised when I received my earrings. I bought from many other brands like mejuri, holly gray, lullajewelry but the sparkle on these earrings are blinding!! I was so pleased with them I proceeded to customise a tennis bracelet with Carat Heritage because I felt that the quality and the pricing was fair. Looking forward to receiving my new bracelet!
Fabulous service, attentive and supportive. Ashley provided great advice and was super responsive. I’m so pleased with the end result - my earrings are beautiful.
Was hesitant at first as I didn’t know if I would be disappointed by the quality of the diamonds, or the setting. I had bought diamond studs from a well known global online jeweller and had been disappointed by the earrings I got. However, Ashley was very patient and obliging in sharing photos and videos of the earring.
After price checks across all the well known online jewellers, could not find a better deal for the same specs of diamond studs. So I took the plunge!
Totally in love with the earrings. They are absolutely gorgeous. Quality of the stones shines right through in how they catch the light, sparkle brilliantly. The setting is also done beautifully.
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!
