What is the best way to farm Gemstones (Amber, Topaz, Ruby, Sapphire and Diamond)?

Solution 1:

From what I've observed, Silver Bokoblins are guaranteed to drop 2 gems, a combination of rubies, sapphires and diamonds. But your best bet is to find rare ore nodes, map them, then make the rounds when you want a lot of gems. Silver Lizalfos and Silver Moblins also drop a couple of gems too.

Solution 2:

  1. I've been scanning amiibos like crazy. Not so great for the non-Zelda amiibos, but definitely helpful with the Zelda amiibos.
  2. Mark spots on the map where there are gemstone clusters and then I hit them up as soon as a blood moon passes.
  3. Don't forget ALL kinds of containers. I may have herped a derp on this one but I only realized a week or 2 ago that the steel containers drop gems, rupees, and ancient tech.
  4. Fighting Taluses. They're hard, but they drop a ton of gems.

Solution 3:

The places I can recommend are the Faron Regions, Gerudo Highlands and/or Goron City/Death Mountain. I have found 1 or 2 at Akkala as well. I'm currently trying to get some sapphires. If I find good places while sapphire hunting, I'll be sure to tell you. I'm also pretty sure that gemstones don't come back on blood moons. I have found they re-spawn the same as other resources. I've found it is best to mine around Akkala or just find Stone Taluses.
