I bought all of my pieces on Shop nbc, they were vendors there years ago. I have a gorgeous suite of multicolor gems, rainbow like looking with white diamonds: earrings, ring and bangle bracelet. Pricey but gorgeous. The rest are Persian turquoise pieces. Their chocolate diamonds line started later and by that time I already had a most stunning 5 ctw chocolate diamond orchid flower ring by Samuel Behnam. People go crazy when I wear it! So I have not purchased LeVians diamonds and therefore cannot judge them. I love Sonia Bitton diamonds anyway, she has a high end soured and connections for the best stuff.
