We especially like David Yurman's dog tags. Called the "Tag Necklace", one is sterling silver with black onyx inlay on a 2.7 mm box chain necklace with a lobster clasp. Its retail price is $550. The "Color Change Garnet Tag Necklace" is a sterling silver piece featuring color change garnet, which is one of the rarest gemstones on earth. The basic colors of this unique mineral are blue-green in daylight, and change to violet-red when the stone is under incandescent light. Its retail price is $3,500. The Pave Diamond DY Tag Necklace ($2,160) is a sterling silver tag featuring white pave diamonds on a box chain necklace. It has a 1.15 total carat weight and is 22" in length.
