Well, first of all there is its good hardness of 7 to 7.5 on the Mohs scale. With a few minor exceptions it applies to all the members of the garnet group, and it is the reason for the excellent wearing qualities of these gemstones. Garnets are relatively insensitive and uncomplicated to work with. The only thing they really don’t like is being knocked about or subjected to improper heat treatment. A further pl us is their high refractive index, the ca use of the garnet’s great brilliance. The shape of the raw crystals is also interesting. Garnet means something like ‘the grainy one’, coming from the Latin ‘granum’, for grain. This makes reference not only to the typical roundish shape of the crystals, but also to the colour of the red garnet, which often puts one in mind of the seeds of a ripe pomegranate. In the Middle Ages, the red garnet was also called the ‘carbuncle stone’. And even today, fantasy names like Arizona ruby, Arizona spinel, Montana ruby or New Mexico ruby are still rife in the trade.
