What would you say when I ask which gemstone is the prettiest? Most will probably say diamond, ruby or sapphire.
But I’m going to show you some of the most beautiful gemstones that you may not know.
This list combines commonly known gems, like opal and amethyst, with some rare and exotic minerals. They represent some of nature’s best creations, and will definitely make you go WOW!
Wulfenite & Mimetite
Vibrant golden yellow wulfenite crystals growing with mimetite.
Naturally formed silver “tree”

This piece is appropriately named “The Helix”.

Ammonite is a rare fossil shell that shows rainbow color iridescent reflection.
Chrysocolla is a blue-green mineral, often found with other copper-rich minerals such as malachite and azurite. And this beautiful piece shows a combination of chrysocolla and malachite.
Red Beryl
Red beryl is one of the rarest gems in the world, much rarer than its mineral family members, emerald and aquamarine. A red beryl gem can cost $10,000 per carat!
Limonite after Marcasite
Purple Fluorite with Calcite
Chrome Tourmaline (Dravite)
Ruby Zoisite
Euclase on Calcite
Rainbow Obsidian
Obsidian is actually a volcanic glass, forming when lava cools quickly. The stone color is black and it has colorful reflections.
Rainbow obsidian and golden obsidian are very desirable as they produce a rainbow-colored and gold-colored sheen respectively, caused by microscopic inclusions of crystals, gas or debris.
