Gems are valuable crafting materials found underground. There are currently 7 gem types. Gems can also be placed on any side of a block after being mined. They are found in any underground layer, except for The Underworld.

Gems are found in the following forms;

• Embedded within Stone Blocks, as the craftable Gemstone Blocks.
• In placed form on blocks underground, including sometimes in Underground Cabins, rarely in the Dungeon, and Amber in the Underground Desert.
• As gem stashes, which are breakable background objects (similar to Coin Stashes), each resembling a rock with gems protruding.
• As a drop from a thrown Geode.
• As a drop from a Gem tree, which can be replanted with Gemcorns. This makes gems farmable.

Gems can also be found in higher concentrations in rare gemstone caves, which can contain multiple gem types lining and embedded within their Stone Blocks.

On the  Windows Phone and 3DS versions, mining gems also has a chance of yielding a Broken Heart during Valentine's Day.

Gemstone cave

A gemstone cave, where higher concentrations of gems can be found. Most of these gems are in placed form, while a few are embedded in Stone.

Two gemstone caves, with walls reflecting the gems found in each.

A gemstone cave is a rare, irregularly shaped room often found in the Cavern layer. It contains a high concentration of placed gems on multiple stone surfaces, as well as a few gems embedded in stone. Most gemstone caves contain one or two types of gemstone, but can rarely contain three or more types. The type of gem found in such caves is easily identifiable by the Gem Wall the cave utilizes, but this wall cannot be collected to obtain any items.

Notes

• Caves with Dirt Walls are considered to be within the surface layer and will not contain gems.
• Gem rarity is not affected by depth; there are as many gems just below the surface as near The Underworld.
• Gems are less common in the Underground Jungle. Regular non-Jungle underground biomes contain much greater quantities.
• Selling Stained Glass can be a profitable way to sell gems:
  • Stained Glass sells for 5 each, with each batch of 20 stained glass selling for 1.
  • Selling batches of Stained Glass is not quite as profitable (and the gems used to craft Multicolored Stained Glass have a greater value than the stained glass) :

Stained Glass	Each	Batch of 20	Gem	Gem value
Purple	20	4	Amethyst	375
Yellow	40	8	Topaz	750
Blue	60	12	Sapphire	1125
Green	80	16	Emerald	15
Multicolored	1	20	Amethyst+Topaz+Sapphire+Emerald+Ruby	60
Red	120	24	Ruby	2250
Orange	160	32	Amber	30

Trivia

• The stats of the gem staves are directly related to the value of the gemstone being used, with the Diamond Staff having a higher damage than the Amethyst Staff.
  • Amber is an exception, being weaker than the Ruby Staff.
• In real life, some gemstones and minerals have been used as a dye, in particular azurite and cinnabar. This could be interpreted as the colored robes found in the crafting menu.
