How to flip the Sapphire
The Sapphire is a free-to-play Old School RuneScape item — “This looks valuable.”. Its Grand Exchange buy limit is 13,000 per 4 hours. Right now it buys at 147 gp and sells at 155 gp — a net margin of 5 gp (3.4% ROI) after the 2% Grand Exchange tax of 3 gp. High alchemy yields 150 gp.
To flip it, place a buy offer near 147 gp and a sell offer near 155 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
