Tunduru River Rainbow Gems is a super cool mix of multiple gemstones that come from Africa.
This 1 gallon bag of gem gravel will have you searching for garnets, sapphires, rubies, spinels, chrysoberyl and zircon. 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 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.
