Is obsidian expensive? How much is it usually?

In fact, people who know obsidian should know that obsidian is actually not expensive. It is not a gem, but a kind of natural glass. The most common obsidian is still relatively cheap in the market. So not many people imitate obsidian, because the cost is low and it wastes time. Like ordinary obsidian, without eyes, a string of bracelets is only a few tens of dollars, and a string of forty or fifty dollars with a little worse color is very common. But like all crystal ornaments, a little personality is different. If obsidian has eyes, the price may go up a lot. Generally speaking, 10mm standard ordinary two-eyed obsidian bracelet will increase by 200. Speaking of specifications, all crystals are like this. The bigger the specification, the more valuable it is. Therefore, obsidian bracelets vary greatly in price according to different specifications such as 8mm, 10mm and 12mm.
