Lab Grown Diamond

Lab grown diamond engagement rings offer everything you want from a natural diamond — the same brilliance, the same fire, the same hardness of 10 on the Mohs scale — at a fraction of the price. If you're shopping for a diamond engagement ring and you're deciding between lab grown and mined, here's the simple truth: the two are chemically, physically, and optically identical. The only difference is where the diamond came from and what you paid for it.

At Bliss Diamond, every lab grown diamond in this collection is IGI-certified and conflict-free. IGI (International Gemological Institute) is the leading grading body for lab grown stones, and each certificate documents the stone's cut, color, clarity, and carat weight using the same 4Cs system used for natural diamonds. You know exactly what you're buying.

Lab grown diamonds are created through one of two processes — High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) — both of which replicate the conditions that produce natural diamonds underground. The result is a real diamond. Not a simulant, not a cubic zirconia, not a moissanite — a diamond, graded and certified as such.

The practical advantage is significant. Lab grown diamonds typically cost 60 to 80 percent less than comparable natural stones, which means your budget goes further. You can choose a larger carat weight, a better color grade, or a more elaborate setting — often all three — compared to what you'd get with a natural diamond at the same price point.

This collection includes lab grown diamond engagement rings across every major style — solitaire, halo, three stone, and pave — in a range of metal options including white gold, yellow gold, rose gold, and platinum. Whether you're drawn to the timeless simplicity of a round brilliant solitaire or the vintage-inspired detail of a cushion-cut halo, you'll find IGI-certified options here priced for real-world engagement ring budgets.

Every purchase includes free shipping, a 180-day guarantee, and a deluxe gift box. Browse the full collection below, or contact our team if you have questions about a specific stone or setting.
