This is a silver necklace by Swiss designer Doris Brother, featuring 20 carats of diamonds. I purchased this set of 6 pieces for 20,640 yen. Although they are artificial diamonds, the instruction manual states that they have a high refractive index, second only to natural diamonds. The photos don't do justice to their beauty, but they actually sparkle brilliantly, making them very beautiful. The diamonds at the tips are 5mm and thick, giving them a luxurious feel. The diamonds towards the back are slightly smaller. The length is about 41cm. It has a 925 stamp. It is silver with platinum plating. Matching earrings are also available.
