Bought from us? We'd love to hear how it went.
Yes. Laboratory-grown diamonds are chemically, physically, and optically identical to mined diamonds — they are real diamonds, simply grown in a lab rather than mined. Every stone from Matts Diamonds is independently graded by IGI.
IGI (the International Gemological Institute) is an independent laboratory that grades each diamond's carat, color, clarity, and cut. Every listing links to its verifiable IGI report so you can confirm the grading yourself.
Yes. Each listing shows the specific stone you will receive, along with a 360° video and its own IGI report — not a stock photo.
