12mm green and red dichroic glass studs. Rainbow Fused glass earrings. Item #2027 Colors change when viewed at different angles. surgical steel posts and backs Larger sized glass earrings come with large backs to handle the weight and the earrings from sagging on the ear. These fused glass kiln fired cabochons are completely handcrafted by me. No two cabochons are exactly the same. There will always be slight variations in the color and size of two cabochons that make up a pair of earrings. Tiny bubbles are also a common occurrence in fired glass and these variations and bubbles are not considered imperfections rather they are evidence of a truly handcrafted cabochon. My photos have been taken outdoors in the natural light so the colors are at their most vibrant.
