FOUR WAYS TO VALUE AN OPAL

1.

Colours have different values depending on how rare they are – red is the rarest. However, a vibrant blue is more costly than a dull red.

2.

If you compare two opals of the same size and quality, the one with a darker body tone will be more valuable.

3.

The rarest kind of opal is the one that reflects brilliant colours across its full face at all angles.

4.

The cleaner an opal’s face and the more defined the pattern, the pricier it is.
