🌟Enameled butterfly necklace on 16” chain

Gorgeous tiny enameled butterfly on yellow gold tone chain. The charm is beautiful and tiny enough to look delicate (see pic with measuring tape for size). On a 16” chain. I cannot find a jewelers mark that indicates it is gold . Though I suspect it is gold plated. It’s been in my possession for 3 years and has not flaked nor turned green. I cleaned it today gently with a jewelers cloth. The clasp had to be repaired and this was recently performed by a certified jeweler. So I am FIRM on the price due to cost of this repair. It would make a lovely gift for anyone loving cloisonné or enameled jewelry. If you need more pics please ask. It has a small makers tag “Giovanni.”
