Loose Columbite Crystals without significant terminations have been polished. They may be used in Jewelry or just placed 'as is' in your collection. They have a moderate SG (4.5) so feel smooth, heavy and thrillingly cold. Some original pyramid and prism crystal faces are preserved. They have a similar luster to hematite but mostly are a deep iridescent graphitic color, very interesting pieces if you want any US$40c/gram. Someone told me Columbite makes you irresistible in love and invincible in war. (these are popular so get your order in before the current stock is depleted)
