The Opal necklace is a members-only piece of equipment in Old School RuneScape.
"I wonder if this is valuable"
Over the last 30 days it traded between 681 and 1,060 gp on the Grand Exchange, averaging 835 gp. About 18,825 units changed hands per day. The price is down 14.8% across that window. The Grand Exchange buy limit is 10,000 every 4 hours. Selling one at the average price costs 16 gp in Grand Exchange tax.
Casting High Level Alchemy returns 630 gp, which is 24.6% below the 30-day average price, so alching a bought one loses money.
