Hi, I'm getting rid of a ring containing a 0.42 carat diamond and I reckon its price must be around the price of 1 oz gold. The material of the ring is white gold and I also have a certificate for it. The certificate states that it's 0.42 ct and natural. Inclusions: Pique II I reckon the white gold ring itself has the lowest value. So, it's the stone that contributes mostly to the price. Comparing similar offers, I reckon it must be worth around 1 oz gold's price. Any suggestions, opinions on what else to look for? Not many people seem to be able to tell its price and dealers of used jewelry give rip-off price estimates (like around 500 USD). I'm very curious about your ideas, suggestions, tips. Or, if you're interested, then just PM me.
