Good-bye, July ~~ Hello, AUGUST!

August Birthstone - Peridot 

   As much as I love diamonds... I am fascinated by colored stones which are unique and beautiful! Stones are found all around the world in different types of deposits. Do you know what makes the difference between emerald, jade, peridot or tsavorite garnet? They are all green, but their chemical compositions and crystal structures are much different! As a gemologist (or, also lovingly referred to as a Gem Geek), I appreciate how these differences in formation and elements cause the beautiful display of colors.

   The picture above shows an array of green-colored gemstones. The birthstone for August is peridot (per-i-doh). This beautiful green gemstone is colored by the element iron which is in its chemical composition. Peridot stones can range from yellowish green to greenish yellow. However, the most sought after hue is a pure green without any yellow or brown modifying hues. 

   The finest and largest peridot come from Myanmar; commercial grade peridot is mined in the United States and China. Most peridot is very clean of inclusions. However, peridot is known for unique inclusions that are identified in gemology as "lily-pads". These inclusions are partially-healed tension halos surrounding a crystal. 

  Peridot is a softer gem and rates 6.5 to 6 out of 10 on the Moh's hardness scale. One thing to keep in mind when wearing peridot is that it is sensitive to temperature changes and chemicals. As with many colored stones, knowing how to care for a gem is important for keeping its beauty alive!
