About Uncut opal

The Uncut opal is a members-only skilling resource in Old School RuneScape.

"This would be worth more cut"

Over the last 30 days it traded between 70 and 96 gp on the Grand Exchange, averaging 78 gp. About 153,272 units changed hands per day. The price is up 7.1% across that window. The Grand Exchange buy limit is 10,000 every 4 hours. Selling one at the average price costs 1 gp in Grand Exchange tax.

Casting High Level Alchemy returns 12 gp, which is 84.6% below the 30-day average price, so alching a bought one loses money.
