Emerald ring

The Emerald ring is a free-to-play Old School RuneScape item — “A valuable ring.”. Its Grand Exchange buy limit is 10,000 per 4 hours. Right now it buys at 510 gp and sells at 532 gp — a net margin of 12 gp (2.4% ROI) after the 2% Grand Exchange tax of 10 gp. High alchemy yields 765 gp.

To flip it, place a buy offer near 510 gp and a sell offer near 532 gp; the spread minus GE tax is your profit. Confidence figures are model estimates from live OSRS Wiki prices, not guarantees — flip responsibly.
