What is Lab-Grown?
Dorsey gemstones are engineered in a lab meant to mimic the conditions in which the stones naturally develop beneath the Earth’s crust. So they have the same physical and chemical properties as mined stones, but without harm caused to the environment or those who mine for them. Lab-grown gemstones are more affordable than mined gemstones but the quality, sparkle, and timelessness factor remains the same. This is the future of beautiful jewelry.
Lab-grown diamond expressed in Carat Total Weight (CTW). Lab-grown sapphire and emerald CTW expressed in Diamond Equivalent Weight.
All Dorsey pieces can be cleaned using warm water and dish soap. Use a soft-bristled toothbrush to gently scrub.
Lab diamond and sapphire pieces set in 14K gold can be cleaned using an ultrasonic cleaner.
