Hello, Welcome to the

Gem Deposits in Tanzania

When you talk about gemstone sources in the world, there is no way you can skip to mention Tanzania. If you don’t mention it then you intend to hide the whole truth about gemstone sources in the world. Always give somebody what he deserves

Tanzania is believed to be the second country with higher amount of gemstones reserves after Madagascar. I think it should be the first because it has Diamonds, Rubies, Sapphires, Emeralds, Spinels, Tsavorites, Tanzanites, Alexandrites and many more.

This purpose of this site is to show you some of the areas that have gemstones which are cheaply available in abundant compared to precious metals. The knowledge also will help Tanzanians to venture into gemstones.
