This is a true Solid Opal Gem. Hand carved by Justine Buckley, set in a Justine Buckley design, 18k yellow gold with diamonds surrounding this magic gem. An N3 Body tone means this opal is classed as a Black Opal, showing rich red, electric green, blue and gold. The opal is 14.04ct and 31x6mm. The setting is 44x10mm. Very Nice!
