TANZANITE BIRTHSTONE

Tanzanite is a birthstone for December, along with zircon, turquoise, and blue topaz. Tanzanite is also the gem for a 24th anniversary.

Found in just one place on earth, tanzanite is a relatively recent discovery. Tiffany & Co named this blue-violet variety of zoisite in honor of Tanzania, where it was first unearthed in 1967.

The instant popularity of this transparent blue-to-violet gem was tied to its vivid color, high clarity, and potential for large cut stones.

Why We Love This Gemstone:

 PLEOCHROIC - Tanzanite is pleochroic, showing three different colors when viewed from different directions. 
ONE PLACE ON EARTH - Commercially mined in only one place, tanzanite is rarer than diamond.
RICH BLUE - Tanzanite's rich blue-to-violet hues can be exceptionally beautiful.

 

 

PERIDOT GEMSTONE

Peridot is the birthstone for August and the 15th anniversary gemstone.

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.

Why We Love This Gemstone:

 

Extraterrestrial - Peridot crystals are found in meteorites: some rare extraterrestrial crystals are even big enough to facet as cut gemstones.

 

Iron Gem - Most gems are colored by impurities such as iron. Peridot's color is intrinsically yellow-green. Higher-quality stones have an intense color.

Seeing Double - Peridot has extremely high double refraction: when you look closely through the gem, you can see two of each pavilion facet.
