Topaz found in Texas is primarily white. Natural Blue Topaz is only found in one place in North America....Mason Texas.
This is the largest gem-quality topaz crystal found in North America, a 1,296 gram (just less than three pounds) pale blue crystal from Mason County.
Here are examples of white Topaz in its raw uncut state and some examples of synthetically colored blue Topaz.
