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.

How Can I Buy Boulder Opal from GemSelect?

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.

Who should wear Boulder Opal?

As with all Opal, this stone should hold a unique value to those who are born in October and those who are celebrating 14 years of marriage. Yes, it’s true; Opal is the accepted stone for your 14th Anniversary. Here at GemSelect we also recommend this stone for men to wear as its quite handsome. Lastly, if you're anyone who has an exquisite taste for jewelry you can and should be wearing Boulder Opal.

What Types of Jewelry Designs are good for Boulder Opal?

Boulder Opal is generally bigger than other types of Opal, so we recommend them for use as Pendants and in Cabochon rings. It is also a rare stone so it’s available only as unique stone not as pairs or lots which will affect the ways it appears in finished jewelry. We suggest using it in unique asymmetrical designs to highlight the stones beauty.

Dimensions are given as;
length x width x depth,
except for round stones which are;
diameter x depth

Select gems by size, not by weight!
Gem varieties vary in density, so carat weight is not a good indication of size

Note: 1ct = 0.2g
