About Boulder Opal

Boulder Opal originates in Australia with many other Opals and is the second rarest type of Opal produced. Boulder Opal is minded at a much lower percentage than the percentage of Black Opal by a 6% variance. This stone is a naturally occurring Matrix that embeds itself in large boulders of ironstone. The iron matrix enhances the Boulder Opal making it more durable and the intensity of its color.

GemSelect’s Boulder Opal is sold only as unique stones because of its rarity. Shopping for this particular stone is quite easy and should be done by browsing for the gemstone you like the most. Some genuinely stunning pieces are available with fantastic color effects.

What colors does the 'Boulder Opal' Display?

Generally speaking, Boulder Opal displays a darker body tone. Some of the stones, however, display colors on the lighter end of the brown spectrum even towards cream types of color. The play-of-color Boulder Opal displays can be extraordinary with colors that move in rainbow-like effects as the viewer peers at the stone. GemSelect’s vast selection of natural Australian untreated Boulder Opal will inspire your creativity and your imagination.

I love gemselect and I have bought a fair amount from them. The only complaint I have is not being able to save gems. I have a lot of projects so i am in the market for a lot of different gems and it's so disappointing to have to delete them all just to purchase one or two that I have saved in my cart.
