A little guidance
Choose the stone that feels right
Diamond
Natural diamonds form in the earth. Laboratory-grown diamonds are made in controlled conditions and have essentially the same chemical, physical, and optical properties. Check each listing for its stated origin and grading details.
Explore IGI certified diamond jewelryMoissanite
Moissanite is a different gemstone made of silicon carbide. Known for its bright sparkle and colorful fire, it is a diamond alternative—not a laboratory-grown diamond.
Explore moissanite jewelryWhat does IGI certified mean?
IGI—the International Gemological Institute—is a gemological laboratory, not a stone type. Its diamond reports identify natural or laboratory-grown origin and describe grading information. The report and individual listing provide the details for your chosen piece.
