These ovals are like lozenges, they are relatively flat, averaging about 7 mm thick. They range from 12 mm to 20 mm in length and are about 10 mm wide. The teardrop shaped is not very pronounced. In fact, I changed my mind several times whether to call them teardrops or ovals. The amethyst is a delicate, light purple. It is perfect for when you want a hint of purple, but don't want to hit anyone over the head with the color. Each strand is 16 inches long and contains approximately 25 beads.
