The Starforge Dancers - Freeform boulder opal earrings that shimmer like twin galaxies in motion, their bright blue, red and green pinfire flashing with every step as if starlight were caught inside the stones.
These large boulder opal doublet dangle earrings shimmer with bright flashes of blue, red and green across their polished freeform stones.
With brightness 4, the colour play is vivid and dynamic, catching the light beautifully as they move.
