Buy OSRS Opal ring
The Opal Ring is a silver ring with an opal set in it for Old School RuneScape. It is a members item that you can wear, trade, and note. It is light, weighing only 0.006 kg, and it takes up one inventory space since it does not stack.
Players make this ring by using a silver bar on a furnace with an opal and a ring mould in their inventory. It only needs level 1 Crafting and gives 10 Crafting experience. Making one is fast and takes just 1.8 seconds.
The ring gives no attack or defence bonuses on its own. Its real value comes from magic. With level 7 Magic, you can cast the Lvl-1 Enchant spell on it using one cosmic rune and one water rune. This turns it into a Ring of Pursuit and gives 17.5 Magic experience.
The Opal Ring is a good pick for players who want cheap jewellery to train Crafting or Magic. It is also a simple step toward getting a Ring of Pursuit without making one yourself.
