10k & green gemstone necklace 10k gold beads w/o clasp onyx? Chalcedony

this is a must have natural gemstone piece. A medium-dark color green that is highly saturated is the most valuable Green Chalcedony or onyx. excellent clarity and hue is also vital Authentic gems will often have small inclusions or variations in color as seen in photos. I am not a gem expert but I have done a lot of research although i can't guarantee that it's onyx it is gemstone and also tested the small space beads, they are at least 10k gold but not 14k. necklace is rope style and unmarked. if you want I have closer pics on macro setting. questions welcome, please review photos. comes in new cotton filled jewelry gift box. other items are display only. the pictures on the stone table are in outside light. gemstone, chakra, crystals, vintage, artisan, classic, minimalist, clean lines, fall, chic, elegant, special occasion, gift, collectible, trendy, baubles, bohemian, formal, jewel tones, timeless
