Handmade in the USA by Ingrid Shourds-Dalton. 
This is a gorgeous rainbow quartz I have added to a golden tone oval and a vintage gold tone chain. 
It's about 10.75 inches from clasp to bottom tip of quartz. The pendant, counting the quartz and the metal oval piece, is about 2.75 inches. 
Please look through all of the pictures. I know there are a lot. None of them really do it justice, but you can see it from different angles and in different lighting.
