Colored stones coming from the African mines are constantly changing with ew gems begin discovered every other week. Buyers have been educated to “purchase it while you can” since the stones are plentiful but they may not be in the next year. This is what happened with the fine Spessartite Garnet, which came from Namibia.

While there is still a supply of stones from Namibia, it is not easy to get, and most of the Spessartite Garnet now originates from Mozambique. The most significant countries that recently produced these stones are Madagascar, Tanzania, and Mozambique. However, Madagascar is well-known for their latest discoveries of Sapphire and Ruby.

As well as the stone above, other gemstones that have been found include:

• Apatite

• Andalusite

• Iolite

• Citrine

• Chrysoberyl

• Kyanite

Mozambique

Mozambique has also become one of the famous producers of Paraiba Tourmaline, and most of the global supply of Paraiba is now originating from Mozambique.

Perhaps the most important mining operation in Mozambique at the moment would be the Gemfields Mozambique Ruby mines. These Rubies are being mined and sold directly the market via an auction.

The most significant of these discoveries were the two latest gemstones. they are called Tanzanite and Tsavorite Garnet.

Tsavorite Garnet

Rhodolite Garnet

Mozambique Metamorphic Belt

The minerals mineral diversity is the most significant portion of the Mozambique Metamorphic Belt, which is a huge continent-scale region more than 600 million years old. It is considered a metamorphic region stretching from Madagascar into northern Kenya. During the early 1970s geologists pursued gemstones along the Kenya-Tanzania boundary.

This lead to a new ruby discovery as well as a remarkable Tsavorite discovery along southeaster Kenya. Nowadays, East Africa is considered the main gemstone-producing region. East Africa has the potential to turn out to be the world’s main expensive stones resources.

This makes the crystal more in perfect forms and properties. Garnets are also belonging to the isometric crystal category, which generates cube-based symmetrical crystals. The most ordinary crystal nature for garnets is the rhombic dodecahedron, which is in a twelve sided form.

Most garnets are available in red tone, leading to the mistaken idea that these stone are all red.

Thus, while huge, clean tourmalines in blue-green and blue tones are obtainable, almost all in pink and red tourmalines will illustrate eye-visible inclusions. The most ordinary inclusions in tourmaline are ruptured as well as, liquid-filled healed fissured. Needle inclusions are also ordinary.

Tourmaline cuts are also wide-ranging due to its hue. With tourmaline’s tough pleochroism, shady tourmalines are cut to illustrate the lighter of the two pleochroic tones. Gems cut with such orientation are regularly with rectangles and emerald cuts because of the extended nature of tourmaline minerals.

Tourmalines with light colors are naturally oriented with the table facet, which is perpendicularly to the c-axis to present the richest tone possible. So, they are often incised as ovals, rounds, and triangles. A quick look at the tourmaline suite display such as this, and faceted stones, cabochon-cut tourmalines are often perceived on the market.
