Most likely, no two are exactly alike. My necklace has deep rich colors.  Actually, a little darker than photographed. All the stones are genuine. Nothing is synthetic. I do wish the lobster claw clasp was a little larger. It goes on easily enough, but I have to slide necklace to front of my neck to remove.  As shown, the strands are interwined. Unlike a thin 18" chain, this  fits closer to my neck, near my clavicles.  It's a substantial piece and the width of the stone chips reduce some of the length when encircled around the neckline.

All the stones have a nice polish. None of chips poke into my neckline, it's comfortable to wear. This has a lot of presence. It's a pretty necklace.
