I found these green jade frog buttons and made them into french clip earrings.  They are a beautiful apple green color.  They are about 1" long by about 5/8" wide.  They are framed on the back with 18k gold vermeil and a french clip (post with clip to keep it firmly in place).

The frog, also known as the heavenly chicken, is symbolic of happiness, good luck, longevity and prosperity.  The frog is believed to promote pleasant dreams. It is an emblem of spring and abundant rain. In Korea a having a dream of a frog is a sign that a son will be born.

Chinese royalty has worn jade for centuries. It is believed to be a spiritual stone and has been called the jewel of heaven. It represents the five principal virtues: charity, modesty, courage, justice and wisdom. From cloudy white to golden brown, light to dark green, to rare lavender, jade is the most highly prized Asian gemstone. Jade has been regarded as the most precious stone for thousands of years. It is believed to protect the wearer and ensure good luck and good health as well as to increase life span.
