Pink tourmaline. October birthstone
A delicate crystal of pink tourmaline, highlighted by a black onyx base. Tourmaline comes in many colours and is an October birthstone. I think that this specimen could work in either a 1:12 or 1:24 scale setting. The first setting photo is in 1:12 scale, the second with 1:24 miniatures.
1/4 inch (0.6 cm) wide, 1/4 inch (0.6 cm) deep and 1/4 inch (0.6 cm) tall.
