There is quite a variety of rough gemstones such as Tourmaline, Aquamarine, Emerald, Sapphire, Topaz, and Quartz, just to name a few. Let’s take a closer look at a few of them that are mined across Latin America and Africa.
Aquamarine is a fascinatingly beautiful gemstone. The name “aquamarine” comes from Latin. Aqua is water, and Mare is sea. Rumor has it that the aquamarine’s strengths are optimally developed when the stone is placed in sunlight-bathed water. There are hardly any other gemstones in the contemporary world of jewelry design that are so refined and available in so many varieties of ways to work with as aquamarine.
Regardless whether the aquamarines are shown as clear, transparent gems in the traditional, classic step cut, or cut in a creative way or in a more contemporary artistic design, they are always beautiful in a fascinating way. Uncut the aquamarine is impressive as well, and if you come across one that has many inclusions brought about by a designer’s idea of how the stone should be cut, an aquamarine can be very beautifully refined to become a stunning and fascinating creation.
The name “emerald” originates from the Greek word “smaragdos” and later through the Ancient French word “esmeralde”. So the name actually has the meaning of “green gemstone”. Through the ages, countless fantastic and sometimes a little “strong” stories have been growing around this beautiful and magnificent gemstone. The very intense and powerful green color of emerald is uncommon among gemstones. See also “Bling Bling”, the CQ Gemfields.
This intense green color is caused by small amount of chromium and vanadium impurities in the stone. Emerald is brittle and often contains flaws otherwise known as inclusions. Unlike other gemstones of the beryl family, inclusions are often tolerated in emerald. Indeed, inclusions are considered as one of the natural characteristics of emerald. Emerald can be found in Colombia, Brazil, Zambia, Pakistan, Nigeria, India, Australia, South Africa, and Zimbabwe. Impressive is also the Central Queensland Sapphire “Gemfest”.

The name “Tourmaline” is derived from the Singhalese expression “tura mali” which means “mixed colored stones”. Tourmalines exhibit a unique spectrum of colors which is second to none in gemstone kingdom. It’s nearly universal popularity is based on the above quality and also are of acceptable quality and affordable to most buyers. Tourmaline occurs in all colors especially red, green and multicolor.
It has been scientifically proven that Tourmaline is not a single mineral, but a group of minerals related in physical and chemical properties. Tourmalines are mined in many places in the world. There are important occurrences in Brazil, Sri Lanka Nigeria, Zimbabwe, and Kenya. If you want to learn more about the difference between cutting diamonds and gemstones, check out this post.
