We also have a highly valuable boulder opal for sale that showcases stunning colours.
What Makes a Solid Opal Stone So Exceptional?
Unlike doublet opals or triplets, solid opals consist entirely of opal and lack any man made clear tops or backings stuck on. This makes solid opal stone more mesmerising to look at and extremely impressive to show off. Black opals in particular display colours vibrantly, making them significantly more valuable and prized than opals with a white or crystal body tone.
Look no further than Johnston Opals when you want a solid opal for sale. Browse our range or get in touch with us today for more details.
