Lab-grown diamonds have the same physical, chemical, and optical properties as mined diamonds. For us, they open up more possibilities in how we design — from distinctive cuts and larger stones to pieces that feel luxurious without being tied to convention.
We choose our diamonds for their cut, proportion, and brilliance, then design around what makes each stone look its best.
What are lab-grown diamonds?
Lab-grown diamonds are real diamonds created in controlled environments using technology that replicates the conditions in which diamonds form naturally.
They have the same crystal structure, hardness, brilliance, and optical properties as mined diamonds. The difference is simply their origin.
For M Grace, that means we can focus on what we care about most: beautiful stones, thoughtful proportions, and jewelry that feels refined and considered.
We choose lab-grown diamonds because they give us more freedom to design around beauty, proportion, and scale.
They allow us to explore distinctive cuts, larger stones, and more expressive combinations while keeping our focus on quality and craftsmanship.
For us, lab-grown is not a compromise. It is simply a different way to create fine jewelry.
Diamond Standards & Certification
We select our lab-grown diamonds for cut, proportion, and overall visual quality, with a focus on bright, well-balanced stones.
Our diamonds are D-E color and VS1 clarity or higher, with over 95% grading D color and VVS2 clarity or higher — and every stone is cut to an Excellent grade. Diamonds of 1 carat or larger are accompanied by an IGI certificate for independent grading and identification.
Materials
We work primarily in 18K gold for our yellow and rose gold pieces, chosen for its rich color, refined finish, and fine-jewelry quality. Select styles are also available in 14K gold.
For our white-metal pieces, we use platinum rather than white gold, chosen for its naturally white tone and durability.
Across every metal, our focus is the same: clean settings, balanced proportions, and a finish that complements the stones.
We believe the details of a diamond should be clear.
Where applicable, our lab-grown diamonds are accompanied by an IGI grading report, which independently documents characteristics such as carat weight, color, clarity, and cut.
Certification availability can vary by stone size and product, so the specific details are listed on each product page where relevant.
From classic shapes to more distinctive cuts, every M Grace piece is designed with the same priorities: beautiful stones, thoughtful proportions, and fine-jewelry craftsmanship.
Lab-grown diamonds give us more freedom in how we create, but the standard stays the same — jewelry that feels refined, considered, and worth wearing often.
