Blackstone is a trade name for a variety of abundant black stones. Some varieties of blackstone have been permanently dyed to enhance their natural color. Blackstone, with its satiny, moderate gloss polish, is great for accenting or mixing with contrasting gemstones, and blends nicely with either gold or silver beads and findings.
