About Orthoclase - History and Introduction
Orthoclase is a rare gemstone that belongs to the feldspar group, which also includes moonstone, amazonite, spectrolite and labradorite. Therefore, orthoclase is sometimes also called "K-spar". Orthoclase gemstones are typically champagne yellow, golden yellow or greenish, though they can be other colors. The name, "orthoclase" is a Greek word meaning "straight fracture", which refers to the cleavage planes of orthoclase being at right angles to each other. Orthoclase is faceted into attractive gemstones and also has an industrial use as a scouring agent in the making of some glasses and ceramics.

This chakra is associated with the color yellow, self-confidence, positive will, productivity, genuine laughter and warmth.

Orthoclase Gemstone and Jewelry Design IdeasBack to Top
Faceted orthoclase gemstones make stunning pendants, rings and earrings. When set in gold, the yellow tones of orthoclase are showcased. Silver settings are also suitable. Clear gemstones such as white sapphire compliment orthoclase well. Orthoclase possesses perfect cleavage, which means gemstones can be split with a single blow, much like topaz. Therefore, extra care should be taken when setting, repolishing or recutting orthoclase. For rings that are worn every day, pronged settings are not recommended, however, for occasional-wear rings, pendants and earrings, pronged settings are fine.
Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamonds by weight in comparison.

Orthoclase Gemstone Jewelry Care and CleaningBack to Top
In order to keep orthoclase gemstones in good condition, some care is necessary. A large component of ordinary dust is quartz, with a hardness of 7 on the Mohs scale. Since orthoclase has a hardness of 6 to 6.5, simply wiping the dust off an orthoclase gemstone can gradually reduce its polish. The solution is to clean your orthoclase gemstones using a soft cloth and only mild soap or detergent if needed. Do not use harsh chemical or cleaners and avoid ultrasonic cleaners and steamers. Always remove orthoclase jewelry before engaging in vigorous physical activity. Store orthoclase away from other gemstones to avoid scratches. It is best to wrap gemstones in soft cloth or place them inside a fabric-lined jewelry box.
