Cascade Geode coasters

Silicone mold for a set of four Cascade Geode coasters. The coasters are about 12.5 cm (5") wide and 9 mm (1/3") thick. 

The coasters are made up of three layers of 3 mm each. Each layer has the same shape but is slightly smaller than the previous layer, which gives the sides of the coasters a unique cascade-like appearance.

There are also 2 Geode tray molds available with the same cascade design, see one of the pictures (for illustrative purposes, this items is only for the coasters mold).
