For your consideration is this beautiful and well made sterling silver pendant. I believe the enamel technique is called plique a jour. It is a quality piece. It is signed 925 Thailand NF on the back as well as the clasp. The person I got this from cleans their sterling but I see evidence of the older patina.
The pendant measures 1 and 1/2 by 7/8 inches including the top piece. The pretty chain measures 17 and 3/4 inches.
All in excellent condition. White on enamel is photo glare.
