The gem bag requires level 25 Crafting and Dungeoneering, as well as 2,000 Dungeoneering tokens (making it the least expensive non-experience reward). It can hold up to 100 uncut gems of the following gem types:
To deposit a gem, just use it with the gem bag or left-click the bag to store any uncut gems in your inventory. You will get the message: "You add the gem[s] to your bag." The gem bag automatically takes gems when they are being picked up by the player since the update on 2 February 2015.
The gem bag can be enhanced for 20,000 Dungeoneering tokens into a gem bag upgrade. However, the upgraded version is available to members only, which means members will no longer be able to use or retrieve gems from it after their subscription ends. Gem bags also cannot be upgraded unless empty.
The gem bag can be used to save inventory space when mining gem rocks in locations such as the Shilo Village mining site, the Lunar Isle mine, the Al Kharid mining site resource dungeon (level 75 in Dungeoneering required) and Prifddinas (requires completion of Plague's End). The bag can also save inventory space when collecting gems dropped by goraks and abyssal demons, who drop gems frequently. Additionally, it can be used to store gems gathered when mining regular rocks, cracking a wall safe in the Rogues Den, training Slayer, and so forth.
The gem bag is also useful when crafting items such as rings, necklaces, bracelets or amulets with a gem. You can have the gem bag and a number of gold ores/bars in your inventory (saving at least 1-2 space for gems to be withdrawn). Walk to a furnace, withdraw a gem, cut it with your chisel (since the gem bag does not store already cut gems), craft it with the gold bar, withdraw another gem, and repeat. However, note that cutting gems tends to cause a much larger loss than making already cut gems into jewellery.
The gem bag can also be used while doing muddy key runs into the wilderness. The muddy chest yields one uncut ruby every time it is opened. Therefore the gem bag can allow a player to carry back much more loot from the chest.
Finally, storing gems in the bag saves bank space. This is particularly useful for free players as they can save up to three spaces if they had all gem types in their bank. Players may only own one gem bag at a time. It should be noted that the gem bag stores 100 gems in total, not 100 gems of each type.
Only one gem bag could be possessed at any time.
