Aquamarine & Diamond Halo Necklace 16" (0.05 ctw)

The pale sea-blue of a natural aquamarine reads best with a little light around it, and that is what the diamond halo does here: a ring of small stones that lifts the blue and makes the 8.4 mm center look larger than it is. It hangs at 16 inches, high on the collarbone, so the color sits where people notice it. Rose gold warms the blue, white gold keeps it cool and icy, yellow gold splits the difference. There is a platinum version too for anyone who would rather never re-plate. Aquamarine is March's birthstone and the stone for a 19th anniversary, so this covers a spring birthday or a long marriage without much thought on your part. It ships in a gift box, ready to hand over.
