A favourite at Rohan Jewellery. We simply love sourcing and working with these spectacular stones. Sapphire (being the mineral Corundum) is the second hardest natural substance found on earth, after diamond. Different trace elements within the stones can give them a huge array of colours although we most commonly think of Sapphires as blue, they can be found in purple, pink, yellow, orange or green any colour, other than red (red corundum is Ruby). The rarest colour sapphire is a beautiful mix of orange and pink, which is known as Padparadscha Sapphire, meaning Lotus flower.
