Sterling Silver Baltic Amber Pendant Necklace

Stunning huuuge amber pendant set in sterling silver. The top of the pendant has a rose and floral design. Jointed 18”necklace with a lobster clasp and a 1” extender. I do not know who the maker is. The necklace was acid tested in a few different places to confirm Sterling silver. The only place that is Marked 925 is on the clasp. The amber itself is about 2” tall. It’s absolutely beautiful, looks very Art Nouveau. Glows how it should greenish under black light. In excellent condition
