Product Description

VVS VS Lab Grown Diamonds White EFG color CVD Diamonds Unpolished Cultivated Diamonds


Can you tell difference between lab and natural diamond?

Crystal shape: most natural diamond crystals are octahedral (eight equilateral triangular faces) crystals, and lab created diamond crystals grow into octahedral and cubic (six equivalent square faces) crystals.

Inclusions: Natural and synthetic diamonds may have various inclusions (fractures, fractures, other crystals, hollow tubes, etc.)

Color: Man made diamonds are usually colorless, nearly colorless, light to dark yellow or tan or other tones; they are less common in red or green. Cultivated diamonds can be treated with the same color as natural diamonds, so any color is possible.

Clarity: The clarity of lab grown diamonds can go from low to high just like natural diamonds.

Cut: The cut of cultivated diamonds is the same as that of natural diamonds-any cut is possible. Round brilliant is the most common shape and cut style for colorless cultivated diamonds.

Does lab grown diamonds have GIA certified?

Yes. GIA is the abbreviation of the Gemological Institute of America. GIA is an authority in the diamond industry. The certificate issued by GIA is recognized by the industry.Diamonds have always been bought for GIA certificates. Diamonds with GIA certificates are not more secure. Consumers will also be more at ease. Maybe you only know that GIA only issues certificates for natural diamonds, but with the increase in synthetic diamonds, gia not only issues certificates for natural diamonds, but also provides synthetic diamond identification and grading services. GIA has been grading laboratory-grown diamonds since 2007. Beginning July 1, 2019, GIA Laboratory-Grown Diamond Reports and identification reports no longer use the term “synthetic.” The GIA Laboratory-Grown Diamond Report includes the standard GIA color, clarity and cut grading scales for reference purposes.
