Antique/Vintage 14K Gold Psi Omega Dental Fraternity Pin Badge with 16 Opals

Description

Tiny but beautiful 14k solid gold (tested), enamel, and opal Psi Omega pin badge.   Psi Omega was founded as a professional fraternity in dentistry in 1892 "
to maintain the standards of the profession, to encourage scientific investigation and literary culture."
The pin features the Greek letters alongside the caduceus and three ivy leaves.
This piece is not dated or marked that I can find.  It is in good condition, with the exception of two chipped opals, one at the 6 o'clock position and the other around the 8 o'clock position.  It really doesn't detract from the piece but can be seen under a loupe.  The enameling is in very crisp condition.  Measures 1/2" by 3/8". Weighs 2.5 grams.  Very nice!
This item has not been cleaned, I will leave that to the buyer.
I have other sorority and fraternity badges in my eBay store, some of which are rare, so please check them out.
