This is a lovely Vintage sterling silver pendant of a Waxing Crescent Moon. This is stamped 925 and Mexico on the back. It also has some maker's marks on the back that I cannot make out.

It has a Pentagram / Star charm dangling from the center.

It measures just under 2 inches long, including the top loop. Quite large.

In excellent condition, needs a little polishing.

This Mexico silver moon jewelry is getting harder and harder to find. 

The Waxing Moon
Waxing Moon means the moon is getting larger in the sky, moving from the New Moon towards the Full Moon. This is a time for spells that attract, that bring positive change, spells for love, good luck, growth. This is a time for new beginnings, to conceptualize ideas, to invoke. At this time the moon represents the Goddess in her Maiden aspect, give praise to Epona, Artemis or one of the other Maiden Goddesses. The period of the waxing moon lasts about 14 days.
'...as the moon waxes and wanes,
and walks three nights in darkness,
so the Goddess once spent three nights
in the kingdom of Death.'
