The Sapphire necklace is a free-to-play Old School RuneScape item — “I wonder if this is valuable.”. Its Grand Exchange buy limit is 18,000 per 4 hours. Right now it buys at 386 gp and sells at 401 gp — a net margin of 7 gp (1.8% ROI) after the 2% Grand Exchange tax of 8 gp. High alchemy yields 630 gp.
