Turquoise is a timeless gemstone, beloved around the world since the
time of ancient Egypt. Turquoise is a stone which is softer than quartz, so it’s
often treated with a colourless wax to harden it to wear. As turquoise is so delicate it can change
colour due to bright light, a chemical reaction due to cosmetics, dust or the
acidity of the skin. Protect your turquoise and keep your jewellery looking beautiful by cleaning it once and awhile with a soft damp towel.
