from 10 reviewsI 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 purchase, unbeatable pricing for this quality. Was worried it might be too large at first but fell in love when I saw it in person!

Bought this for Mother's Day and my mum was simply delighted. She said it was super bright and luminous! Appreciate the nice packaging box and bag and fast same day delivery!

My fiance loves it so much! Thank you for making us such a beautiful 3 carat diamond ring!

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!

Clean, chic, and guilt-free. These diamond studs are now part of my daily uniform.

Love the ring we received. It’s really bright and catches the light perfectly. Have received many compliments about the sparkle since I started wearing it.


The Art of Handpicked Perfection
More Than a Certificate
At Carat Heritage, we believe that true brilliance isn’t just about meeting standards—it’s about exceeding them. While certificates like IGI or GIA provide valuable technical insights into a diamond’s quality, they can never fully capture the beauty, fire, and soul of each stone.
That’s why every diamond we use is more than just certified; it’s handpicked by our experts, who examine each stone with their own eyes.
