Cool Color Spectrums and Luminous Ocean Hues

Blue green opals are highly prized for their cool color palettes. Chemically, these colors are dictated by the physical size of the sub microscopic silica spheres within the gemstone structure. Spheres ranging from 0.1 microns to 0.15 microns in size diffract light specifically at the shorter wavelength end of the spectrum, producing electric green, bright teal, and deep royal blue flashes.

These serene, cool shades are highly versatile and pair beautifully with sterling silver, white gold, or platinum settings. Perfect for everyday casual wear, our solid blue green opals are ethically sourced directly from legendary Australian mining fields.
