Victorian Carved Mother of Pearl Necklace on Vintage Chain- Flower

This is a spectacular hand-carved mother of pearl Victorian era Pendant. There are three pieces of MOP— the white MOP heart base, a middle layer of gray MOP, and the final white layer in the shape of a flower. Someone later added it to a 17 inch vintage woven chain (somewhat tarnished). It could easily be swapped for a different chain if desired, but I’m leaving it as I found it. 
Due to its age, it is unfarmed, natural mother of pearl, and the thickness and weight of the piece are uncommon. There are no visible chips in the piece, and only a few light scratches that aren’t obvious. Length is just under 2” from top to bottom and 1.4” at its widest point.
