Real diamonds
with honest origins

The singular difference between our diamonds and mined diamonds is the origin. Every Great Heights diamond is lab-grown using a craft that mirrors the natural growing process. They're molecularly identical, but without the destructive force of mining or murky ethics.

Quality, no matter
which stone you choose

The 4C's can be overwhelming. That’s why every one of our diamonds passes rigorous inspection, optimizing for cut, color, and clarity. You can feel confident knowing you're getting a quality diamond that's flawless to the naked eye.

Our Cut

Ideal to Excellent

The diamond's cut affects the way light is captured and reflected from your stone. The full spectrum ranges from Fair (dull or glassy appearance) to Ideal / Excellent (reflecting the most possible light). Great Heights only offers diamonds that are Ideal to Excellent.

Our Color

Colorless (D) to Near Colorless (J)

The color scale ranges from D (colorless) to Z (considerably yellow). The less color, the higher the value of your stone. Great Heights diamonds sit between D and J, with near-perfect color.

Our Clarity

Flawless (FL) to Slightly Included (SI2)

Clarity refers to the birthmarks in a diamond, ranging from visible nicks and flaws (I3) to 100% inclusion-free diamonds (FL). Every Great Heights diamond is SI2 and above, with few to no inclusions visible to the naked eye.
