Now, if you're looking to buy white opal rings, it's important to know something of the prices they fetch.
The cost of white opal is less than that of other opals, such as black and boulder opals, as we've already indicated. The reasons for this are that white opals are the most common form of opal, and darker opals are more valued for their beautiful contrast of colors.
But that doesn't mean that white opals should be overlooked. They can be extremely beautiful in their own right, with the glorious whiteness of the opal enlivened by a glittering galaxy of iridescent flakes.
Some of the most beautiful of Australian white opals can fetch a price of around $150 per carat, which isn't too shabby. Of course, additional factors, such as the color patterns and brightness of the opal, synthetic, and other factors can affect the final price.
