Although frequently confused with Ruby, Spinel stands on its own merits. Available in a striking array of colours, its long history includes any famous large Spinels still in existence. Increasing demand for Ruby alternatives has rekindled appreciation for Spinel’s rich red colour and history. Spinel crystals are so perfect, in Burma they are said to be ‘polished by the spirits’. Many of the famous ‘Rubies’ of history were actually Spinel’s. The most valued spinel colours are bright red, cobalt blue, and vivid pink and orange. Pale lavender is more affordable. Spinel was recently added as an August birthstone, sharing this month with Peridot.
