The Diamond is the most valuable gem after the rare Prismatic Shard, and one of the most useful items to keep in stock. Every villager either likes or loves it, so it is a safe gift for anyone. In a Crystalarium it gives the best steady income of any gem. It is also a crafting part for the Ring of Yoba, the Geode Crusher and Fairy Dust, and at the Forge it adds random upgrades to a melee weapon. A single Diamond at Grandpa's Shrine even buys a second evaluation. Ten Diamonds traded to the Dwarf in the Volcano Dungeon buy The Diamond Hunter, which turns every rock into a small chance of another Diamond.
The in-game description reads: A rare and valuable gem.
Location
Diamond Nodes appear in The Mines from floor 50 downwards. Breaking one with a pickaxe gives a Diamond. Gem Nodes can also hold Diamonds, and they appear in The Mines, the Skull Cavern, the Quarry and the Volcano Dungeon.
Several monsters drop Diamonds now and then. Dwarvish Sentries in the Volcano Dungeon have the best chance, at one in ten. Some slimes, Duggies and golems drop them rarely. Once the bottom of The Mines has been reached, any monster has a very small chance to drop one. Metal crates in the Volcano Dungeon can hold them as well.
Fishing Treasure Chests and panning can turn up Diamonds, and so can the Garbage Cans in town after the bottom of The Mines. The Trout Derby offers a Diamond as one of its prizes. The Prize Machine gives five Diamonds as one of its later prizes.
An Ice Pip or Stonefish Fish Pond can produce a Diamond once its population reaches nine.
The Statue Of Endless Fortune gives a Diamond on the birthdays of Evelyn, Gus, Jodi, Krobus, Marnie, Maru and Willy. On other days it has a one in four chance to produce one.
After reading The Diamond Hunter, any rock broken with a pickaxe has a small chance to drop a Diamond.
Prices
A Diamond sells for three times as much as an Emerald or Ruby. The Gemologist profession at Mining level 10 adds thirty percent to that price, as it does for every gem and mineral.
The Crystalarium is where Diamonds earn their keep. A copy takes five days, which works out to about 150g a day per machine. Emerald and Ruby earn about 120g a day. Star Shards and Helvite, the best geode minerals for the machine, earn about 144g and 130g. A shed full of Diamond Crystalariums therefore gives the strongest steady income of any gem.
The Help Wanted board outside Pierre's General Store can ask for a Diamond once floor 40 of The Mines has been reached. That request pays three times the Diamond's sale price, so it is worth taking whenever it appears.
Uses
Crafting a Ring of Yoba needs Iron Bars, Gold Bars and one Diamond. The recipe is learned at Combat level 7, and the ring sometimes shields the wearer from damage.
Clint's Cave Patrol special order rewards the Geode Crusher recipe. Building one takes Gold Bars, Stone and a Diamond. The crusher then opens geodes at home for free.
Finishing The Pirate's Wife quest on Ginger Island teaches Fairy Dust. Crafting a Diamond with a Fairy Rose makes it. Sprinkling Fairy Dust on a machine such as a Keg or Furnace finishes its current product at once.
At the Forge in the Volcano Dungeon, a Diamond fills every remaining forge slot on a melee weapon with a random upgrade.
Placing a Diamond in Grandpa's Shrine asks for a new evaluation. This only works while fewer than four candles are lit, and it gives a second chance at the full reward.
Trading one Diamond to the Desert Trader in the Calico Desert buys a Triple Shot Espresso. Trading ten to the Dwarf in the Volcano Dungeon buys The Diamond Hunter.
Several Fish Ponds ask for one or two Diamonds before they grow, including those of Lava Eel, Sturgeon and Spook Fish. The Raccoon at the Giant Stump can also ask for one once his requests reach the later stages. With the Remixed Bundles, a Diamond is one of the options for the Treasure Hunter's Bundle in the Boiler Room.
Donating the first Diamond to Gunther adds it to the museum's mineral collection. Putting a Diamond and Cloth in the Sewing Machine makes the dyeable Pendant Shirt. On its own, a Diamond works as a white dye.

Notes
Ten Diamonds for The Diamond Hunter is a steep price. The book's chance applies to every rock mined by hand from then on, so the cost is spread across every later trip underground.
Keep at least one Diamond in a chest at all times. Grandpa's Shrine, the Geode Crusher, Help Wanted requests and Fish Pond quests can all ask for one at short notice.
