- "Dig deep to unearth buried treasure."
- — Bejeweled 3, game menu description
Diamond Mine is a game mode in Bejeweled 3 and Bejeweled Classic. In the PC, Mac, Nintendo DS, Xbox 360, and PlayStation 3 versions of Bejeweled 3, it becomes available by completing any four mini-quests of the first Lost Relic of Bejeweled in Quest. In the mobile version, it becomes available by reaching level 5 in Classic.
In Diamond Mine, the game board resembles a large digging machine with the gems placed inside it. The board also includes dirt squares, which make up the lower rows. The object of Diamond Mine is to clear the earth by matching gems next to it. Special Gem effects can remove dirt as well. Between the sixth and seventh rows of the board is a white line called the Dig Line. Clearing all the earth above this line causes any remaining earth to rise until the top of it reaches the fourth row, and new earth appears at the bottom to simulate digging deeper into the ground. A depth indicator increases by ten meters for each row of new earth added to the bottom.
Each game of Diamond Mine begins with only four basic gem types: red, yellow, green, and white. Blue and violet gems appear as the game progresses, while orange gems do not appear at all in Diamond Mine.
Diamond Mine also features rocks, stones, and boulders. These are denser than regular earth; thus, they need extra adjacent matches to clear them. Like dirt, Special Gem effects can break down and remove rocky ground as well. Upon reaching 200 meters in Diamond Mine, the game mode introduces a new type of rocky earth called dark rock. Unlike rocks, stones, and boulders, only Special Gem effects can remove dark rocks.
During each game of Diamond Mine, Hypercubes fall into the game board every now and then. Hypercubes are also embedded in random dirt squares and can be used when uncovered, but these particular Hypercubes only appear from 40 to 120 meters.
At the side of the board is the Timer Bar. Each Diamond Mine game begins with a time limit of 90 seconds. Clearing all the earth above the Dig Line adds 30 seconds to the Timer Bar, while clearing all the earth on the game board will add 90 seconds. In Bejeweled Classic, the respective time bonuses given are 25 and 70 seconds instead. It is possible for the Timer Bar to exceed its original time limit.
When the Timer Bar reaches 30 seconds, "The Voice" will announce a brief warning about the amount of time remaining. When the Timer Bar reaches 15 seconds, the digging machinery emits a pulsing red glow and a warning sound plays; these effects intensify as the time limit approaches expiration. When the Timer Bar runs out, the game ends in which the machinery breaks down in a series of explosions.
Upon completing a game of Diamond Mine, a Stats Screen appears with various information about the finished game.
Unlike other game modes, players earn points in Diamond Mine by collecting various treasures found embedded in random dirt squares. Upon unearthing treasure, it places itself in a glass container suspended beneath the game score. The container is absent in the mobile version of Bejeweled 3; uncovered treasure floats toward the game score and then disappears instead. Below is a list of the different kinds of treasures in Diamond Mine, along with their respective point values and descriptions of each type.
|This consists of sparkling nuggets. It appears throughout each game of Diamond Mine, but it becomes less frequent as the game board reaches further depths.||2,000–6,000|
|These are shimmering crystals that come in four colors of increasing value: cyan, blue, violet, and red. They do not appear until the game board reaches 140 meters. The point values rewarded upon unearthing diamonds is actually smaller than the point numbers that appear. This oddity exists only in the PC and Mac versions, and it is unknown if it is intentional or not. Bejeweled fans refer the oddity as a "Crystal Tax".||10,000–25,000|
|These are objects that are often decorated with jewels. They appear throughout each game of Diamond Mine until the game board exceeds 990 meters. Upon unearthing an artifact, it displays its name and point value. Diamond Mine features a total of 46 different artifacts. Sometimes it is possible to collect the same artifact twice in a single game.||7,500–150,000|
- Upon playing Diamond Mine for the first time, the gems will be arranged in a specific pattern and an informative message appears over a yellow gem. This happens only if a Gold Rush mini-quest was not played before accessing Diamond Mine.
- Because of this, the tutorial appears only in versions of Bejeweled 3 that feature Quest.
- Pausing the game in Diamond Mine causes the gems to vanish, but they reappear upon resuming the game. This most likely happens to prevent "cheating."
- When the game board moves up, existing gems in the upper rows are pushed off the top of the board.
- If there are no possible matches when the game board moves up, a random basic gem will transform into a Hypercube.
- It is possible to keep swapping gems after removing all the earth above the Dig Line. However, the Timer Bar will continue counting down.
- If the Timer Bar runs out, the game board will move up by itself.

- The name of this game mode is a reference to the fact that Bejeweled was originally known as Diamond Mine, but the name was changed because it was too similar to that of an existing game called Diamond Mines.
- Points in Diamond Mine are rewarded in the form of currency, except in Bejeweled Classic and the mobile version of Bejeweled 3.
- The ground darkens as each game of Diamond Mine progresses. This feature does not affect gameplay, and it exists only in the PC, Mac, Xbox 360, and PlayStation 3 versions of Bejeweled 3.
- When the depth indicator exceeds 990 meters, it will display MAX (in most versions of Bejeweled 3) or 999 (in the Nintendo DS version) throughout the rest of the game.
- Based on evidence present in the game files of Bejeweled 3, the original name of this game mode was Buried Treasure.
- The music featured in this game mode is even known as such in the official Bejeweled 3 soundtrack.
