Buying Tips from Our Gemologists

Deep, rich saturation with flashes of red or blue is most valuable. Steer clear of heavily dark stones that appear black in low light, and beware of glass or synthetic amethyst sold as natural.

Caring for Your Amethyst

Avoid prolonged direct sunlight, which can fade color over time. Clean with warm soapy water; avoid heat and ultrasonic cleaners on heat-treated stones.
