Mother of pearl or shell — the creamy iridescent white sections Cultured opal or lab opal inlay — some of the brighter glowing areas with that soft fire effect Black onyx or jet-colored resin/stone — the sharp black channel work Turquoise or dyed stone — the aqua sections Possibly coral or spiny oyster tones in the orange/red sections The opal/shell mix gives it that Santa Fe gallery jewelry feel rather than classic old pawn style. It almost has an Art Deco Southwest vibe. 3” wide 2“ tall
