Stunning! Black Ceramic. Four Diamond. 160.0282.3 Swiss Made Tungsten Steel Band Scratchproof Watersealed High-Tech 071/R20282712. Non-Working. Many of the jewelry items listed are antique, vintage, and/or pre-owned. Items have had a life before found. Items may show evidence of that previous life; signs of wear, dents, scratches, oxidation, broken stones, etc. I strive to be accurate and transparent in the descriptions of these pieces. I'm not a gemologists. I choose pieces based on their overall aesthetic and how well they accessorize. I try my best to accurately describe the stones in my jewelry items but cannot absolutely guarantee them. I want the true age of the piece to be represented, so I do not perform any type of cleaning or polishing. If the item is oxidized when I acquire it, that is precisely how you will receive it.
