What is a lab-created diamond?

A lab-created diamond (also called lab-grown or synthetic diamond) is a real diamond grown in a laboratory using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) processes. Lab diamonds have the same chemical composition (carbon), crystal structure, optical properties, and physical hardness (10 on the Mohs scale) as natural mined diamonds. They are graded using the same 4Cs standards by the same labs (GIA, IGI).

Are lab-created diamonds real diamonds?

Yes, lab-created diamonds are real diamonds. They are chemically, physically, and optically identical to natural diamonds. The only difference is their origin — one formed underground over billions of years, the other was grown in a controlled laboratory environment over a few weeks. The FTC (Federal Trade Commission) confirmed in 2018 that lab-grown diamonds are diamonds and updated its definition to remove the word "natural" from the definition of diamond.

Are lab diamonds worth buying?

Lab diamonds offer excellent value for buyers who prioritize size and quality over rarity. They cost 60–80% less than comparable natural diamonds, allowing buyers to choose a significantly larger stone or higher quality grades for the same budget. The trade-off is that lab diamonds have minimal resale value and do not hold value over time as natural diamonds can. They are an excellent choice for those who want the look and feel of a diamond at a much lower price.

Collectors Diamond Quality - (Our Best VS (VS1 or VS2 Clarity, [F,G] Color)

Our "Collectors Diamond Quality" is truly our best. VS (VS1 or VS2) clarity and F,G color gives these diamonds "colorless" color and "near flawless" clarity. Choose this quality if you're looking for the signature quality and color—ideal for engagement rings and statement pieces. We highly recommend this choice for those who do not find price to be an issue.

Fine Diamond Quality - (SI (SI1 or SI2) Clarity, [I,J] Color)

For those looking for a lower price point than our "Prestige" quality and are willing to have a little less white color in their diamond, "Fine" quality may be the preferred choice. These diamonds have SI (SI1 or SI2) clarity and I,J color. We consider this quality to be the "Best Bang for the Buck". They are gorgeous stones which have plenty of fire and depth. They make any piece of diamond jewelry—from diamond rings and diamond pendants to diamond earrings—one to own.
