About Diamond

The Diamond is a free-to-play skilling resource in Old School RuneScape.

"This looks valuable"

Over the last 30 days it traded between 1,522 and 1,641 gp on the Grand Exchange, averaging 1,592 gp. About 1,360,176 units changed hands per day. The price is down 3.3% across that window. The Grand Exchange buy limit is 11,000 every 4 hours. Selling one at the average price costs 31 gp in Grand Exchange tax.

Casting High Level Alchemy returns 1,200 gp, which is 24.6% below the 30-day average price, so alching a bought one loses money.
