Break rocks with Pickaxe or Mega Bombs, collect resources, and open geodes. This strategy is not new to seasoned Stardew Valley Players. However, we can’t say the same for newbies.

It’s one of many unique minerals in-game, but we’ll talk about everything you should know about the item.

What’s an Obsidian?

Despite its purple egg-shaped visuals, this item sells for 200g and 260g with Gemologist. It’s one of 53 minerals available for donation to Gunther’s Museum and Library.

Geodes contain a variety of exotic minerals in the game.

If you’re looking at the Mines, you can find this mineral below floors 21 and beyond – by chance. In Skull Cavern, it doesn’t matter how deep you go since the area has endless(ish) levels. However, it’s worth mentioning the specifics since it’s found by breaking open Magma Geode and Omni Geode.
