Gorgeous !!   RLM- Robert Lee Morris Soho Sculptural, Y Shaped, Lariat ? Style, Necklace, Silver Tone Metal with Silver Plate? ( not sure, but RLM frequently is either 925 Silver or Silver Plate, Not Stamped)  High Polished Silver Shine, Hammered, Finish.  Hook Closure with 3 inch extender.  I measured the necklace to be approx 14 inches in length by closing the necklace with the hook, and holding it up, from top to bottom.  Approx 17 inch long with extender. Has the RLM Soho Logo Tag.  Longest geometric piece on the very end ( longest point) is approx 6 cm long and approx 1.5 cm wide, at the widest point, but they all vary in size cascading down.

Condition:  New without tags, never worn.
