Type	Currency
Values	Small: 2G — Large: 10G
First appearance	Downwell (2015)

Gems are the currency of the well, dropped by dead enemies, red-tinged breakable blocks and gem veins. Small gems are worth 2G and large ones 10G.

Gems are spent in the Shop, and your lifetime total also unlocks palettes and styles. Collecting quickly enough builds a streak — 100 gems in a short window triggers the Gem High state, temporarily powering up your weapon.

Uncollected gems fade after a few seconds, and they sink much more slowly in the water of the Aquifer and the void of Limbo. The Gem Attractor upgrade doubles the radius from which they fly to you; Gem Powered recharges your Gunboots as you collect; Popping Gems turns each pickup into a free upward shot.
