Spinles seem to attract confusion! In history they have often been confused with rubies and sapphires, in fact the Black Prince's Ruby adorning the Imperial State Crown of England is actually a fine red spinel. In more recent times, spinel was one of the first gems successfully grown in a laboratory so it is used for many of the synthetic birthstone colors. In spite of all this, natural Spinel is still being mined and is gaining more recognition among gem and jewelry buyers.
With its hardness of 8 and its wide range of available colors, natural spinel makes a great choice for all types of jewelry including rings.
