Uncut opal detail.png

An uncut opal is a members only item, classified as a type of semi-precious gem in RuneScape. Uncut opals can be cut with a chisel resulting in an opal or a crushed gem. Successfully cutting an opal grants the player 15 Crafting experience, smashing grants 3.8. Opals are the lowest level gemstone, the most common, and are worth very little.

Opals are found mostly with the Mining skill, however only by mining a gem rock, which are located mostly in Shilo Village although there are a few others found elsewhere. Uncut opals can also be found while panning at the Digsite near the River Salve, or they may be stolen from H.A.M members via the Thieving skill. There is usually a high supply of these items on the market, so trading with another player will also quickly produce them.

Processing and uses[edit | edit source]

Opals are sometimes used in bulk to train Crafting, but this is slow. When cutting opals, many of the gems get accidentally crushed into a crushed gem. This continues to happen commonly even at high levels, resulting in only 3.8 Crafting experience. Opals can be smelted with silver bars to create opal jewellery. Using the chisel on an already cut opal will make 12 opal bolt tips (this operation will never smash a gem) and gives the player 1.5 Fletching experience per gem. Opal tips are used to tip bronze bolts which can then be enchanted.
