Rose cut diamonds have been having something of a resurgence. They are cut with fewer facets than modern diamonds, and have a softer look to them as a result of that cut.
This necklace by Sethi Couture features a quarter carat of white diamonds set into 18k yellow gold. It includes a 24 inch paperclip chain. It is also available in white or rose gold.
This is priced at USD$1,960.
