Two Natural Ruby Crystals in Matrix.
Beautiful specimen piece for any collection to display.
They weight a tad over 44g a piece.
Rubies are made under extreme heat and pressure below the earth. When compressed, oxygen and aluminum atoms turn into corundum. This mineral, along with the presence of chromium, creates rubies and their distinct hue. If ferric iron is also present, the ruby will be a shade of orange or pink.
