Aquamarine @ cliptomania.com





The gemstone aquamarine is blue-green to blue and is a variety of the mineral beryl.  This group of minerals is most famous for the green emerald.  Yet despite this association aquamarine is transparent and full of clarity whereas emerald tends to be hazy and have inclusions.  Also aquamarine gets its color from iron impurities within colorless beryl crystals whereas emerald gets its color from trace amounts of chromium and vanadium.  

Most aquamarine comes from Brazil with smaller deposits found in Australia, Myanmar or Burma, China, India, Kenya, Madagascar, Mozambique, Nambia, Nigeria, Zambia and Zimbabwe as well as in several US states. 





The more saturated the color of aquamarine is, the more valuable it is in price. The most popular cut for the gemstone are round, oval, pear and cushion.  Aquamarine can be heat treated to enhance its color but most times when you see aquamarine it is in its natural form.

Aquamarine gemstone jewelry can safely be cleaned with warn soapy water with or without using a tooth brush.  After cleaning the gemstone wipe it with a soft cloth.  And be sure when wearing this jewelry to avoid contact with household cleaning chemicals and keep it away from intense heat to prevent permanent damage to the gemstone.  

Always store gemstone jewelry inside a fabric lined box or wrap it in a soft cloth then store it separately from other gemstones.

 February's birthstone is Amethyst.

Amethyst is the purple form of quartz, and the most desired of the quartz family. Shades include dark purple, lilac, lavender or mauve, yet top quality stones will be a medium deep purple with rose colored flashes.

Did you know ancient Romans and Greeks made drinking glasses of Ameythist in belief it would keep them from getting drunk?



February's alternate stone is Onyx.

Onyx is formed of bands of chalcedony in alternating colors.  The black variety is the most famous, yet not as common as onyx displaying colored bands.

Did you know slabs of onyx were famously used by Mies van der Rohe in Villa Tugendhat at Brno to create a shimmering semi-translucent interior wall?




February's birth crystal is also the Amethyst.

Amethyst stones can fade in sunlight. It is recommended that jewelry not be worn while sunbathing, swimming, in a solarium, or near a black light. Sudden temperature changes can also be harmful.

Did you know in 1993 a 9-foot cave was found near Maine which contained more than a ton of amethyst crystals
