Product Description for Min .50ct 7x5mm Oval Pink Spinel
Spinel ranks 8 on the Mohs' scale and occurs naturally in every color, making it one of a handful of naturally beautiful gemstones that are not treated or color enhanced. Spinel has been called an "imposter" gem for some time, because its strong resemblance to corundum often has it mislabeled ruby or sapphire, including the 170-carat Black Prince Ruby and 352-carat Timor Ruby, which are both set in the British Crown Jewels but are both actually bright red spinels, not rubies.
