June 2014 Newsletter: Rare Malaia Garnet

 Rare Malaia Garnet

Rare garnets are among our favorite gemstones. They combine very good hardness with a high refractive index that gives well-cut stones excellent brilliance. Since they are singly refractive, they display a purity of color that can be very attractive. And they are almost always untreated. 

Garnets mainly belong to 6 species -- pyrope, almandine, grossularite, spessartite, andradite and uvarovite. Tsavorite and hessonite, for example, belong to the grossularite species, and demantoid to the andradite species. But some garnet varieties are hybrids. Rhodolite is a mixture of pyrope and almandine, while mali garnet is a mixture of grossularite and andradite.

One of the recently discovered hybrids is a pyrope-almandine-spessartite mixture that is known in the trade as Malaia or Malaya garnet. You may also see it marketed under the name Imperial garnet. It is found in a range of hues, from slightly pinkish orange to reddish orange or yellowish orange. Tone can vary from light to dark. 

Malaia Garnet Colors

Malaia garnet was first discovered in the early 1970's in the Umba River valley that borders northern Tanzania and southern Kenya. Deposits of similar material were also found in 1993 in southern Tanzania. There are also reports of some specimens from Madagascar and Sri Lanka, but all of the material we have seen in the market is from east Africa.

The preferred spelling for this garnet is "Malaia" rather than "Malaya" since the latter misleadingly suggests the gem is associated in some way with Malaysia. The word malaia actually comes from Swahili, where it means "prostitute". Miners gave it this name because when the gem was first discovered local dealers wouldn't buy it because it didn't fit any of the known garnet varieties. Now it is regarded as a rare and special garnet and it commands a premium price in the market. High quality finished stones over 3 carats are especially valuable.

We have recently acquired some fine Malaia garnet rough, and have just cut a number of beautiful pieces, including several rare stones over 10 carats.

Ask the Gem Experts

Each month we answer questions from our customers. We welcome your questions and you can submit a question from our contact page.

Normally on your website when you indicate the stone as unheated, does it mean that it is unheated at your end only and does not mean that is definitely not heat treated at the source (for example at the mine itself where the stone rough was unearthed)? RY, Singapore

When we list a gem as unheated, it means that that it was not heated at any point since it was mined from the earth. Generally this is a fact that can be confirmed by gemological testing, by means of microscopic examination of inclusions, which will show the effects of high temperature heating. Some low temperature heating cannot currently be detected. You'll find that most of our unheated rubies and sapphires include reports from independent gemological laboratories. Some gems, such as spinel and the various garnet varieties, are almost never heat treated. 

 

I've been reading about the military coup in Thailand, has it been affecting your business? PK, USA

Though Thailand has one of the fastest growing economies in Asia, it also has a history of political turmoil. From time to time the army steps in to cool things down. When this happens, it is usually a time of stability, though with restrictions on freedom of speech and assembly. For us it is business as usual. The airports are open and FedEx and the post are functioning. We expect things will get back to normal in a few months, with an eventual return to a democratically elected government. This is a cycle we have seen many times.

 

 

All the best in gems,

Arnold, Rung & Ron
