A beautiful Natural Ruby Crystal. Well formed Red Crystal Specimen of Corundum. Ruby has a long and storied history in its gemmy form, as a coveted gemstone around the world. These days most of the ruby you’ll find in mainstream jewellery shops is ‘created’, grown in labs to get the perfect shade and clarity popular among the public. Just one of the interesting features of this mineral. This Specimen has good classic Ruby Crystal hexagonal face. Nice colour too. Pics taken outside and under UVA to show off fluorescence. The bright pics are taken with UVA Torch.

Ruby’s are Red and all other Corundum are Sapphires. The name is from Sanskrit “kuruvinda” meaning Ruby. A rare sapphire is a Padparadscha which is a pinky peach colour, found in Sri Lanka. Ruby is the second hardest natural mineral. The Element Chromium is what causes the Red colour in Ruby. The best shade of red for a Ruby is Pigeon Blood Red. Ruby can be any shade of red up to almost pink. They are the most amazing Gemstone and in my mind way better than Blood Diamonds.
Corundum is a crystalline form of aluminium oxide, containing traces of iron, titanium, vanadium and chromium. This makes gem quality corundum rare. The crystal shape of Corundum is hexagonal but they don’t always come in that form. Ruby has a hardness of 9 on the Mohs scale.
