I got this information from elle:
New Jade (Serpentine) makes an exceptional meditation stone. It helps you to find inner peace. Serpentine was carried in ancient Assyria to request the gods and goddesses to provide double blessings. Nursing women used it to regulate their milk supply. Serpentine can be placed directly on the skin. It is an aid to kidney and stomach complaints, relaxes cramps and menstrual pain and helps women who are unable to reach orgasm due to tension.
The picture shows a perfect match.
