Crafting ruby jewellery
|Artisan's outfit recommended|
|Inputs (3,512,880)||Outputs (5,322,240)|
1,680 × Gold bar (1,725,360)
1,680 × Ruby (1,787,520)
1,680 × Ruby necklace (5,322,240)
Ruby necklaces are made by combining a gold bar and a ruby. If you are a member, you only need to bring rubies to the furnace as the gold bars will be pulled directly from your Metal Bank. Each Ruby Necklace gives a profit of 1,077 and each load of 28 is worth 30,156. Making a bank preset of 28 rubies will help minimize time spent banking.
The process is tedious, but requires a fairly small amount of attention. You need a furnace that is close to a bank, such as the one in Lumbridge (which is near the Lumbridge Market bank) or the ones in the Artisan's Workshop. Each full load takes 50.4 seconds to craft, plus a few seconds for running and interface manipulation. With maximum efficiency, you can get close to a run per minute for a total of 1,680 Ruby Necklaces per hour, resulting in a profit of 1,809,360 per hour.
It should be noted that Grand Exchange has a buy limit of 5,000 per 4 hours for rubies. It is possible to work around the limit by letting the order fill while doing other activities, directly trading with other players, or by using alternate accounts. The profit for making 5,000 necklaces is 5,385,000.
Other necklaces may also make a profit using the same method. Before you start, you may want to check to see if another necklace has a higher profit as all gold jewellery takes the same amount of time to craft.
The Artisan's outfit is a bonus experience set from Treasure Hunter and as a reward from Stealing Creation costing 100 reward points per piece. Each item alone provides 1% more Crafting experience when worn. When all of the set is equipped, the total bonus increases to 6%.
