This is a lovely Victorian necklace that measures 22" long from the lock in the back to the oval gold plate center pendant. From this point there is a dangle freely pendant 2" long. While these appear together I do not believe the originated together. I believe the dangle of onyx and glass micro mosaic flowers where added at a later time. The chain is gold filled the clasp is hallmarked 585. The first pendant is oval on beveled black onyx is a bouquet of flowers in shades of pink, red, green. hey appear to be roses made of very tiny glass pieces embedded in the onyx. the onyx on this piece has a tight hairline crack at the bottom. The second dangle piece is much more ornate, a long splash of finely set glass pieces which are tulips, cornflowers, roses and foliage. These are done by a master . The are so finely set that they are flush at the surface. I believe this is an earlier piece made by a fine artist. The onyx has some flea bites along the bevel in several places. Together this necklace looks like an important piece of jewelry. I recently wore it to a wedding and got rave reviews. It looks like it is set in gold but none of it test as such.
