Sterling and Onyx Rosary from PL

Matte black onxy beads feel like silk to the touch. This rosary is also very new and so it hasn't been cleaned. It has a PL mark on the crucifix, but the centermedal is unmarked. The bright spot on the middle is where the seller (presumably) did an acid spot test on the silver. It will disappear once the piece is cleaned. Another test on a more hidden area of the centermedal confirms the 925 sterling content. All of the assembly of the rosary is sterling and the hanging length is approx 26 inches.
