Hi everyone, In light of the conversation of opals I wanted to comment
on blue opal.
Blue opal has a tendancy to change color and become opaque in dry
weather, however it can also revert back to its original state after
time in humid weather. My suggestion to possibly prevent cracking is
to remember to water your opals.
My favorite opals are blue opal and boulder opals. The color in blue
opal is magnificent.
