Stunning Light show of 25ct 2mm-3mm Ethiopian Fire Opals and the a pear cut 9mm London Blue Topaz 1.7ct. Clasp is a solid 14k gold spring clasp and necklace is 16 inches. Please remember Opals are the flashiest under bright light so I took photos with the camera flash on and off. Opals change color under every light that is what makes them unique.
