If gold were $930 a troy ounce when you settled the transaction you could reasonabally expect to receive 561.70 from most dealers. As to what it is woth I would say roughly 802 or so based upon a 930 gold price. At 18k you have 75% gold. An ounce is 31.103 grams. However it is my experience that even though the gold may be marked 18k, it's composition may be less than marked.
