Peridot, Spinel and Sardonyx ( August Birthstones)


Peridot Oval Ring


Peridot is the Birthstone for the month of August & also considered The traditional 15th wedding anniversary gift as well.

Peridot Halo Ring


The word peridot comes from the Arabic “Faridat”, which means gem.


Peridot Oval 


Peridot is Olivine and a silicate Mineral Igneous rock such as volcanic basalt. Its yellow-green color is dependent on the iron contents within the structure of the gem.

Peridot pear shape


Peridot was called Evening Emerald by the ancient Romans because while deep green emeralds darkened to where they almost looked black at night in candlelight, peridots still shimmered under candlelight and their color didn’t darken.

Peridot Cabochon


The ancient Egyptians mined peridot on the Red Sea island of Zabargad, the source for many large fine peridots in the world’s museums. The Egyptians called it the “gem of the sun.” Today this gem is still prized for its restful yellowish-green hues and long history. Large strongly colored, examples can be spectacular, and attractive smaller gems are available for jewelry at all price points.

# August Birthstone Spinel:





Did you know that spinel is just added an official birthstone for the month of august? This August birthstone is traditionally given as a 22nd wedding anniversary gift.


Spinel is singly refractive and lacks pleochroism stone. It comes in a variety of colors, red, pink, blue, black, violet, and lavender. In general, red spinel is the most desirable color. Violet and purple or lavender stones tend to be less attractive and less in demand than others. 



Intense red and pink are caused by a trace of chromium, orange, and purple stones owe their color to a mixture of iron and chromium, and violet to blue color by a trace amount of iron. 



In ancient times spinel was known as Balas Rubies, some of these fine stones become the treasured property of kings and emperors and passed through the hands of many as spoils of war, one of the famous examples is the so-called "Black Prince's Ruby". The famous 14th-century Black Prince’s Ruby in the British Imperial Crown is Red Spinel.
