Rose Pear Shape Diamond Pendant White Gold.  This modern necklace features a small round rose cut diamond above a .74 carat pear shaped rose cut diamond and is set in 14 karat white gold. The chain measures 18 inches and has very dainty little links which give the piece an overall delicate look. The white gold accentuates the color of the diamonds and the simple design gets out of the way of their natural beauty.
