How much is a opal ring worth?

Answer 1

It depends how many carats it weighes, a carat in jewelery is about a twentieth of a gram, or 0.2grams. Another factor to how much it is worth is what type of opal it is, there is fire, blue, black and white, (but black being the most of value)all known as precious opal. One other thing is what metal and how many karats it is. Say if it is old weighing 14kts, it may be worth over $500, an opal in zinc, may be worth only $150. But it all matters about the stone. Finally is it's color, clarity, and sometimes it's transparenty.
