Our Story
Our partners Ashley & Belle met as former colleagues working at Facebook (now Meta) with a shared passion for jewelry. Now both mothers, they decided to build a business that allows for greater work-life balance for women and mothers.
Partnering with esteemed jeweler families with three generations of expertise, we bring together time-honored craftsmanship and modern innovation to offer exceptional quality at accessible prices. Our master artisans, renowned for their work with natural diamonds and colored gemstones, are now expanding into the world of lab-grown diamonds with Carat Heritage.
We handpick the best lab diamonds with stunning qualities which are indistinguishable from a natural diamond - but without any unsustainable mining practises.
We are a predominantly online brand but we do offer viewing appointments at our Centrepoint office. This model reduces our overheads and keeps our prices low for our customers.
On most days, you will find us busy in our office discussing custom designs with our customers or shooting content for our brand.

The Art of Handpicked Perfection
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.
A Higher Standard of Beauty
Not all diamonds with the same grade are created equal. Two stones might share identical certificates, but subtle differences in brilliance, symmetry, or sparkle can set one apart. Our handpicking process goes beyond the 4Cs and ensures only diamonds that radiate exceptional beauty make it into our designs.
A Human Touch in a Certified World
Our jewelry comes with IGI (International Gemological Institute) certificates which can tell you about the 4 Cs—Cut, Color, Clarity, and Carat. But as experts with years of experience, we look for the “fifth C”: Character. This ensures that the diamonds we select have a personality and presence that certificates can’t quantify.
Uncompromising Quality
Our hand-selection process means we reject any stone that doesn’t meet our rigorous standards. There can be visible flaws that certificates can't evaluate and in addition, we only use diamonds graded VS1 clarity and F color & above. Every diamond used in your jewelry is a reflection of our commitment to excellence.
A Promise of Brilliance
By combining certification with expert selection, your diamond jewelry will not only meet industry standards but redefine them. When you wear your jewelry, you’re wearing something as rare and unique as you are.
At Carat Heritage, we don’t settle for “good enough.” Because when it comes to creating jewelry that celebrates life’s brightest moments, only perfection will do.
