Sterling Silver Necklace and Opal Teardrop Pendant

Sterling Silver Necklace and Opal Teardrop Pendant. I bought this new a long time ago for myself and was told that the stone was real Opal/ Opals but I never had it appraised so I can’t guarantee if it’s real or not. This has age, has been worn a bunch and shows all over wear to the necklace and the pendant. This has imperfections including scratches, scrapes, dents, bends/kinks, discolorations and it may have other imperfections but it is still a very pretty necklace. Measurements are rough approximate measurements and colors may be off because of lighting.
