Here's a rare bird... canary Yellow Heart Lab Diamond, in a large, 3ct size.

In this case, the stone is beautifully cut, Heart Brilliant. Lots of bright flashes.

I'd grade the face up color as Fancy Vivid Yellow - IGI gave it Intense Yellow.

No matter, it's clearly yellow, and with really nice purity of color. It was grown and cut in Kyiv, Ukraine, in 2022.

The stone was grown HPHT, in the color you see - no post growth treatment.

The clarity and crystal nature of the stone is identical to the best diamonds mined from the earth.

It's going to look amazing in a ring. Or pendant... sky's the limit.
