This trillion-shaped gemstone is for someone looking for an Oregon sunstone with high schiller. This schiller effect is a bit difficult to capture on camera. The schiller is caused by tiny copper inclusions which look like individual snowflakes on camera, but in sunlight they blend together to give the stone a shimmer that looks like the bottom of a new copper pot. The schiller effect on this particular stone is highly directional. Due to sunstone’s hardness (approx. 6.5), we recommend setting this stone in a pendant. https://youtu.be/03MgbUMxOC8 GEMSTONE: Sunstone ORIGIN: Oregon WEIGHT: 2.58 Carat COLOR: Peach/Pink CUT: Trillion SIZE Approx. 5.56 x 5.53 x 5.95 mm QUALITY: High Schiller TREATMENT: None
