*** FINAL REDUCTION. ***
This piece has been in my inventory for a long, long time. I couldn't list it in good conscience until I knew exactly what I was dealing with.
It looks antique. At first glance one would think it's Victorian, or maybe even Georgian. Alas, it's not. Two things are dead giveaways (aside from the hallmarks, which I will get to): 1.) The clasp is a safety clasp - these weren't invented until at least 1910 and not used widespread until around 1930. 2.) The pearls - they are definitely cultured. They are too round, too perfect and too numerous on a relatively inexpensive piece of jewelry to be natural.
There are tiny hallmarks on this piece, but it took me until recently to read them due to not having a decent magnification tool outside of a loupe. They are older marks from the country of Portugal, post-1938 but prior to the markings that are commonly used today. As this piece uses jeweler's cement to secure the pearls, and not modern glue, I can circa date this piece to around 1940.
Although this piece is hallmarked as gold and silver, the mark's do not indicate the quality of the materials, so I have also acid tested this piece. The rose gold is at least 14K and the silver is coin (800) or better.
The floral motif brooch is set with 17 rough cut diamonds, 3 post set cultured pearls and one pearl drop at the base.
It measures 1.58" from side to side, and 1.69" from top to bottom. It weighs 9.1 grams.
The back has a safety clasp and tube hinge, which work perfectly. There is also a hidden bail, so that the piece can be worn upon a necklace chain as a lavaliere. (The bail shows very little evidence of wear, which would also be an indicator that this piece is not a genuine Victorian piece.)
Condition is very good, with no damages or repairs. This piece has been cleaned, but has not been polished.
