DOUBLE RAINBOW GEMS

A 2 pack of Tunduru River Rainbow Gems!!

Tunduru River Rainbow Gems is a super cool mix of multiple gemstones that come from Africa.

You will receive (2) 1 gallon bags of our Tunduru River rainbow gem gravel.  You will be searching for garnets, sapphires, rubies, spinels, chrysoberyl and zircon in a natural Montana sapphire gravel base.  These are not huge gems but some will be big enough to cut a small finished gemstone.  They can also be kept as a collection where you can admire the fantastic colors.   We had purchased this Tunduru River gem mix about 10 years ago and have searched for it ever since.  Thankfully, we were finally able to get more of this colorful, gemmy material to share with you.  We know you’ll enjoy this gem gravel!

These gems are added to our El Dorado sapphire gravel.  The chance of finding a natural Montana sapphire is slight but still there.
