This is a very pretty Australian boulder opal cabochon with a white base and lots of red and pink fire. Would look beautiful set either length or widthways as a pendant or as a ring, either on its own or alongside some faceted stones for extra sparkle. For inspiration on setting stones like this, click here to see a video of making a gorgeous pendant with a similar boulder opal cabochon and read our meet the jeweller interview for some more opal inspiration.

• Cabochon
• Size: approximately 14 x 7mm
• Has a hardness of 5.5-6 on the Mohs scale
• Natural genuine gemstone - no treatment - as these are natural stones they may have slight surface imperfections. As opal cutters "chase the fire," following the seam through the host rock to reveal its brilliance, boulder opals sometimes have slightly uneven surfaces. These undulations are left to preserve the opal layer and its fire, avoiding unnecessary loss during cutting.
• Birthstone of October
• Healing properties: calming, comforting and happiness
• Country of origin: Australia
• Sold individually, the opal pictured is the one you will receive on purchase
