Pyrope/Almandine and Rhodolite Garnet Information

Rhodolite GarnetAll these Garnets are members of the Isomophoros series of Garnets. Pyrope has a blood red color with few inclusions. Almandite Garnet is deep red to violet and can show asterism. Exceptionally beautiful Pyrope/Almandine Garnet the color of fine French Claret wine comes from Mozambique and is known as ‘Mozambique Garnet.’ This has become highly prized when it looks very beautiful. Rhodolite Garnet is a combination of pyrope and almandine and is a red to reddish pink and violet also called ‘grape garnet’. This is the superior variety of Isomophoros Garnet as it is far brighter.

Value of Pyrope, Almandine and Rhodolite Garnet

As with all stones the 4C’s apply. Small dark Garnets are very cheap. When the size gets larger the value increases enormously – if the stone is clean. Mozambique Garnets and especially Rhodolite Garnet are a good investment as they are very similar to Rubelite Tourmalines. In the past year they have increased in price as the Tourmalines have, but not at the same level – yet! Large Rhodolite Garnet is gaining some notoriety and considerable collectability.

Garnets are so underrated. We are big fans of all things Garnet and specialise in gems and beads. They are going up in price, along with all gemstones but I feel they are a worthy investment. If someone puts a large pink Rhodolite in front of me I will have to hide my delight as I haggle!
