1.3" Fluorescent Ruby and Almandine Garnets in Matrix - Russia

Fluorescent Ruby and Almandine Garnets in Matrix - Russia #247162

This is a gorgeous, colorful metamorphic rock formation that's composed of ruby, almandine garnet, biotite, and plagioclase feldspar. It comes from Khit Ostrov, Russia, a region known for its crystal formations that include ruby (corundum), fluorapatite, titanite, kyanite, rutile, and more.

This specimen has been mounted to an acrylic display base with mineral tack. Under shortwave UV, the ruby crystals exhibit a vibrant red-pink fluorescence.

Ruby is a variety of corundum that's distinguished for its bright red color. The colors of this mineral can vary between pinkish-red to a deeper blood-red. It's one of the most popular gemstone for both its alluring color and hardness (9 on Mohs hardness scale), making it suitable for nearly all types of jewelry. The other gem variety of corundum, sapphire, encompasses the remaining colors (mainly blue), while still having the same chemical makeup. For this reason ruby can be classified as red sapphire, but typically is left as its own gemstone variety due to its historical significance and appealing coloration.
