How to flip the Opal
The Opal is a members-only Old School RuneScape item — “A semi precious stone.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 145 gp and sells at 152 gp — a net margin of 4 gp (2.8% ROI) after the 2% Grand Exchange tax of 3 gp. High alchemy yields 60 gp.
To flip it, place a buy offer near 145 gp and a sell offer near 152 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
