Your cart is empty. The Fantasia brand of "AAA" Grade Corundum Ruby rough you are ordering is 100% natural and imported directly from India to Fantasia Mining's USA rock yard. We only have a limited quantity of this "AAA" grade rough and it is not something we are always able to get. This is not facet or gem grade but it has an amazing ruby red color for cabbing, tumbling, wire wrapping, reiki or keeping in it's natural form as a decorative rock. Your order will contain multiple pieces of this spectacular material which is equal to or greater than the weight purchased. This is the highest grade Corundum Ruby we have available and there is a significant quality difference between this grade and our mine run, high grade, and premium grade sapphire and ruby materials.
If you are looking for blue sapphire the Fantasia brand of Blue Sapphire rough is also available here on Amazon in multiple grades. To see this material you can enter "Fantasia Blue Sapphire" in any Amazon search bar and click on the listing for that product.
VERY IMPORTANT: This is rough natural material which means you are receiving it exactly how it came out of the ground. All pictures were taken with the stones being wet which helps to show the materials true colors and clarity. It may not have the same appearance when dry unless it has been polished, tumbled, or cabbed. If you have any questions about this feel free to contact Fantasia Mining prior to purchase so we can ensure you will be completely satisfied with your order.

For ruby, I expected fairly poorly quality, so these vastly exceeded my expectations. Most of them have relatively high ruby percentages (vs matrix and other inclusions), and their shapes should make them much easier to tumble.

These are nice for tumbling. My kid enjoys the colors of the minerals we got, pinks, purples, greens, oranges!

These came in today and i was very pleased. I got 2 smaller ones and a good size one. They all have great color. Fantasia mining is a great company i will continue to order from them.

Good solid pieces. A few rather large pieces and lots of quality med. size stones. Will work perfectly for my projects.

I have been tumbling these in coarse grit for three weeks now. Others had posted on here and other places about corundum taking a long time to tumble because it's so hard. After one week, I didn't really have anything to show except spent grit and mud. After two weeks, it was more of the same, but the smaller pieces that I were in the mix had cleaned up nicely. I'm on the tail end of the third week of tumbling with coarse grit and I expect that I'll have revealed more of the quality in this rough.

I received a bag of about 20 rocks that look exactly like what is pictured. After scrubbing them with dish soap and a tooth brush, quite a bit of red and purple could be seen. If you then put them under a black light, the ruby will glow blood red and the purple rock takes on a bluish purple glow. I was very pleased with the size of the sample and working on clearing the matrix of other stone that surrounds most pieces, revealing even more color in these stones. Will definitely order this again, and other gem samples this company offers.

These are incredibly beautiful. The rock is very dense and certain pieces when held up to the light glow red. I would buy these again.
