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.
