Natural Slate - Large 5 To 7 Inch Stones. PH Neutral. Perfect for Aquascaping and Igwami Aquariums, Reptile and Amphibian Enclosures, Stone Carving and Crafts (10 lbs)

These are real slate, and 99.99% pure slate. Jet black color with virtually no marbling. I bought all three sizes and am VERY pleased with all. Washing is recommended but scrubbing is not really necessary. They look really beautiful in a freshwater fish aquarium. The shapes are varied as expected, but perfect and natural. Unless you have unlimited time to search for less expensive sources and options, these are worth the expense.

Slate was well package - no breakage, great large pieces of slate. Fast delivery!

ordered 2 lots of the 5-7 inch stones, all arrived intact and were absolutely perfect for the slate cave i wanted to build. will definitely order these again in the future!

Ordered the 5-7” rocks and one out of them all was 5” roughly.. the rest were in the 3-4” and yeah they are nice flat rocks but for the price.. they are just rocks.. no crazy cool patterns or designs just boring flat small rocks. Probably wouldn’t buy again as it was a gamble based on reviews and I didn’t feel like size was worth the price.

They look good and I am generally happy with them. My only issue is in the variance in thickness. Some are more slender than others which kinda ruined my plans for my aquascape because I was hoping more mostly thinner pieces. In the end I got it looking nice but I would have preferred if they could keep the thickness uniform.
