Ruby Bracelets
Ruby is a red colored variety of the mineral Corundum, which can also be called as a red colored Sapphire due to its same composition as of a Sapphire. This blood red coloured gemstone is composed of Aluminium Oxide and the signature colour of it comes from the presence of Chromium along with the basic composition. Just like a Sapphire, Ruby has a Hardness of 9 out of 10 on the Moh’s Scale of Hardness and hence is also the second hardest mineral found on the Earth.
