A compact microcrystalline quartz, chalcedony (pronounced "cal-SID-nee") is a tough, durable stone that is ideal for carving, cabochons, and beads. Pure chalcedony is white; individual chalcedonies are labeled by the colors that come from trace minerals. Most varieties of chalcedony are dyed to enhance their color. The color of red dyed chalcedony can range from pinkish-red to medium-red.

The cushion cut is a classic style; it combines features of the oval cut with a deep cut and large facets.
