This is a marvelously colored, sparkly vintage costume jewelry brooch, or pin, signed Sarah Coventry.  We haven’t been able to find the name of this design yet, but it looks like a Tree of Life, a Family Tree, or a Mother’s Tree theme.

Eleven multicolored, faceted stones are prong set on a gold tone tree that measures about 2” high and 1 ¾” wide. 

In excellent condition.  Safety clasp in fine working order.
