Spheres - Half Drilled
These spherically shaped gemstones have been half-drilled. This means a short hole has been drilled on one spot on the sphere (it does not go all the way through). SS "Pearl Cup" Earposts (one example shown in picture) can be used with the half-drilled spheres for making earrings. They also can be used with a SS Bail with Pin to make drops that can be strung on a necklace or chain. Green Aventurine in picture is no longer available. Sold individually.

Discounted item notes: Remaining Amethyst is pale or has chevron or pale brown/white areas in the gemstone. Remaining Chrysoprase is pale or has black to brown inclusions. Some of the Chrysoprase also has slight surface irregularities that co-incide with the light brown inclusions.
Pentagon - Unset Gemstone
Samples shown in Tiger Eye, Black Obsidian (no longer available) and Rose Quartz - these measure about 24x20mm. Similar to a cabochon, these pentagon shapes are flat on the back; they have bevel cut sides. All surfaces are polished.
