Mining and Gems
February 19, 2026 at 03:16 PM
Initial version
Mining is a gathering activity in inZOI that allows Zois to collect raw stones, minerals, and gemstones from rocky deposits found throughout the world. The mining system was introduced with the free Island Getaway update alongside the Cahaya region, and mining spots are available in all three playable areas: Dowon, Bliss Bay, and Cahaya. Raw gemstones can be refined into polished jewels at a Crafting Table, sold for Meow, or tracked in the Collection Log. Mining ties into the Handiwork skill and the broader gathering and crafting ecosystem.
Mining spots appear as rocky patches and shiny deposits on the ground in parks, gardens, farmlands, and other open areas. Most grassy areas throughout the game world will have at least a few mining spots scattered around. To mine, walk your Zoi to a mining deposit and select the "Mine with Tools" action. If your Zoi has a pickaxe in their inventory, they will use it automatically. Mining without a tool is possible but significantly less efficient — a pickaxe is strongly recommended for any serious gathering.
Each mining spot yields a random selection of materials when mined. The type of materials you receive depends on the mining spot category (see below), the tier of pickaxe used, and some element of randomness. Mining spots respawn over time, so you can revisit the same areas on subsequent days.
Mining deposits come in different visual categories that affect which materials can be obtained:
Standard spots — yield common stones, iron ore, and occasionally low-tier raw gemstones. Found everywhere.
Golden spots — have a golden shimmer and tend to yield rarer gemstones. Certain gems can only be found in golden mining spots.
Silver spots — metallic silver appearance. Good source of silver ore and diamonds. Diamond specifically appears more reliably in silver mining spots when the Zoi is in a "Feeling Concentrated" mood state.
Mixed spots — can yield a variety of materials from different categories. Some exclusive gemstones only appear in mixed deposits.
Pickaxes are the primary mining tool and dramatically improve both mining speed and the quality of materials obtained. Pickaxes can be purchased at the Farm Store in Cahaya (located in the bottom-right section of the map) or crafted at any Crafting Table using gathered materials. The available tiers are:
Stone Pickaxe — the most basic tier. Can be crafted from stone and twigs at a Crafting Table. Suitable for gathering common materials like regular stones and iron ore.
Copper Pickaxe — available at the Farm Store. Improved mining speed and slightly better gem drop rates compared to stone.
Steel Pickaxe — available at the Farm Store. A reliable mid-tier option that unlocks access to mid-range gemstones.
Gold Pickaxe — crafted at a Crafting Table using gold materials. Significantly improved gem discovery rates. Enables finding raw diamonds and other high-value stones.
Diamond Pickaxe — the highest tier, crafted using diamond materials. Provides the best chance of finding the rarest gemstones including Pink Diamond and other top-tier specimens.
Crafting higher-tier pickaxes requires materials obtained from lower-tier mining, creating a natural progression loop. You mine with a Stone Pickaxe to gather copper, use copper to craft or buy a better pickaxe, and continue upgrading.
inZOI features a diverse collection of raw gemstones organized into several families. The Collection Log organizes gems into rows by mineral family:
The first row of the gemstone collection consists of mica minerals:
Red Mica — found in Bliss Bay mining spots. A common mica variant with a distinctive reddish hue.
Green Mica — exclusively found in Dowon. This is one of the few gemstones tied to a specific region, making it a must-collect for players who primarily mine in Cahaya or Bliss Bay.
The second row features sodalite-type minerals:
Blue Sodalite Mineral — found in Bliss Bay. A blue-toned mineral that is relatively accessible with mid-tier pickaxes.
The third row contains crystal specimens:
Soul Reap Crystal — found in Bliss Bay. A rare crystal type that may require focused mining sessions to obtain.
Turquoise Raw Stone — found in Bliss Bay and Cahaya. A semi-precious gemstone with a distinctive blue-green color.
Opal Rough (also called Black Opal Raw Stone) — available from various mining spots. Valued for its color-shifting properties when cut.
Diamond — found in silver mining spots. Drop rates improve significantly when the Zoi is in a "Feeling Concentrated" mood state. Use consumables like donuts to maintain concentration during long mining sessions.
Pink Diamond — the rarest gemstone in the game. Described by players as "the toughest to collect." Requires a Diamond Pickaxe and significant patience. Often found in golden or mixed mining spots.
Larimar — a unique gemstone that can only be collected from underwater sandpiles while snorkeling. Not obtainable through standard mining. Requires snorkeling gear from Cahaya.
Pearl — found in underwater sandpiles (while snorkeling) and occasionally in beach-area mining spots in Cahaya and Bliss Bay. Pearls require collecting 8 stones to complete the collection entry and are considered extremely rare.
In addition to gemstones, mining yields functional materials:
Iron Ore — common from most mining spots. Used in tool crafting.
Silver Ore — obtained from silver-type mining spots. Used for crafting Silver Pickaxes and other items.
Stone — the most basic mining yield. Used in crafting Stone Pickaxes and other starter tools.
Cahaya is the primary mining region with the highest concentration of mining spots:
Xiang Park — one of the most reliable mining areas in the game. Multiple deposits in a relatively compact space.
Bliss Garden — a peaceful area that frequently yields gemstones.
Cahaya Farmland — mining spots scattered across the agricultural areas.
Underwater sandpiles — accessible while snorkeling. The only source for Larimar and a source of Pearls.
Dowon has mining spots primarily around:
Harang River Park — mining deposits found along the riverbanks alongside the fishing spots. This is the only location for Green Mica.
Various park and green spaces throughout the city.
Bliss Bay features mining spots near:
Bliss Bay School area — a known hotspot for rare gems according to the community.
Beach-adjacent green areas and gardens.
Raw gemstones can be refined into polished jewels at a Crafting Table, which is purchasable through Build Mode. Gem cutting is tied to the Handiwork skill — one of the skills in inZOI. As your Zoi’s Handiwork skill level increases, they unlock more advanced cutting techniques that produce higher-quality jewels. Higher-quality polished jewels sell for significantly more Meow than raw gemstones.
The cutting process takes time and produces a finished jewel that can be:
Sold for Meow through a Secondhand Sale Stall or the Pocket Market app
Displayed as decoration in your Zoi’s home
Used as materials for crafting higher-tier tools (e.g., Jewel Fishing Rod, Diamond Pickaxe)
Added to character appearances as accessories
Gems can be sold in the same ways as other items: through a Secondhand Sale Stall placed via Build Mode or through the Pocket Market smartphone app. Raw gemstones sell for less than their polished counterparts, so investing time in gem cutting via the Crafting Table is generally worthwhile. The rarer the gem, the higher the sale price. Pink Diamond and Diamond are among the most valuable items you can sell.
Mining can be a steady income source, though it typically earns less per hour than some other activities like fishing premium species from boats or advanced cooking recipes. The primary appeal for many players is Collection Log completion rather than pure profit.
All collected gemstones and mined materials are tracked in the Collection Log under the Mining category. The Collection Log shows which gemstones you have found and which remain undiscovered. Completing gemstone sets unlocks exclusive furniture rewards. The Jewels section of the Collection Log separately tracks polished jewels created at Crafting Tables.
Completing the full gemstone collection is considered one of the more challenging achievements in inZOI due to location-exclusive gems (Green Mica in Dowon, Larimar from underwater sandpiles) and the extreme rarity of Pink Diamond. Community discussions suggest that maintaining a "Feeling Concentrated" mood state and using consumables like donuts to sustain focus significantly improves rare gem drop rates.
Buy a pickaxe from the Farm Store in Cahaya as early as possible. Mining by hand is very slow.
Upgrade your pickaxe progressively. Each tier unlocks new gemstone possibilities.
Visit Xiang Park in Cahaya for the densest concentration of mining spots.
Remember to visit Dowon specifically for Green Mica — it cannot be found anywhere else.
For Larimar and Pearl, invest in snorkeling gear from Cahaya and mine the underwater sandpiles.
Keep your Zoi in a "Feeling Concentrated" mood state when hunting for diamonds and rare gems. Consumables like donuts help maintain this.
Cut raw gems at a Crafting Table before selling. Polished jewels are worth significantly more than raw stones.
Mining pairs well with fishing and gardening since mining spots are often near fishing and farming areas in Cahaya.
