10x8 or 9x7 Oregon Sunstone | Rose Cut Oval Cabochon with Schiller | Per Stone
10x8 or 9x7 Oregon Sunstone | Rose Cut Oval Cabochon with Schiller | Per Stone
These rose cut cabochons represent a genuinely rare combination of cut, size, and optical character. The rose cut top — a faceted upper surface paired with a high domed profile — is uncommonly seen in Oregon Sunstone material, and the high dome amplifies the schiller dramatically by increasing the depth through which light interacts with the copper platelets. Available in 10x8mm and 9x7mm, these stones are cut to slightly larger tolerances and may measure up to 0.2mm beyond standard dimensions, meaning they will not fit most pre-made bezels and are best suited for custom fabrication or experienced wire wrapping. This specific combination of origin material, cut style, size, and schiller intensity is not something that can be easily restocked — once these are gone, they are gone.
