About TMS Gems
Tom Schneider, a native Californian, grew up surrounded by gems and minerals in his parents' rock shop. It has been since this time that he has had a fascination with these treasures from the Earth.
Since 1980, Tom has been selling gem rough to cutter, both hobbyist and professional alike. Today, he travels the globe in search of the finest gem rough available so he can offer it to you.
With his personal philosophy of honesty and integrity, let Tom Schneider become your supplier of choice for rough and cut gemstones.
