There is a complex model of necklace pendant. Quad poly mesh creates body. Tune quality by using meshsmooth iterations. Gems have true dimensions and looks good. Mapping on body provides texturing and painting over model. There is HQ model - gems have not intersects with geometry and creates clear visualisations and animations for your purposes [ad, own portfolio, impression cgi etc]. Project contains silver material with setup including maps and parameters and diamond material with tuned dispersion effect. Looks like diamond gems and swarovsky crystals both! Presented images rendered with included scene with vray setup. It needs only hdr image on environment. Thanks!
