Colour Citrine’s attractive colour, plus the durability and affordability it shares with most other quartzes, makes it the top-selling yellow-to-orange gem. A saturated yellow to reddish orange colour free of brownish tints is prized in citrine, although in the contemporary market, citrine’s most popular shade is an earthy hue- a deep brownish or reddish orange.

Citrine’s colours range from pale brownish yellow shades like this one to intense reddish orange hues. - Robert Weldon
Since natural citrine is rare, most of the citrine on the market is the result of heat treatment, which causes some amethyst to change colour from undesirable pale violet to attractive yellow. The amethyst’s original hue can determine the richness of the resulting citrine’s yellow.

Lime-coloured citrine can result from heat treatment of smoky quartz. The gem’s designer used some frosted facets to highlight its trendy colour. – Lydia Dyer, gem courtesy John Dyer & Co
Clarity Dealers look for citrines without colour zoning or visible inclusions. Much of the faceted citrine in the market is eye-clean, meaning it lacks eye-visible inclusions.

Cut Although citrine is available in standard shapes and sizes, in recent years many high-end jewellery designers and gem carvers have fashioned the warm yellow gem into unusual cuts for jewellery and carvings.
