White Agate & Blue Topaz Pendant

White Agate & Blue Topaz Pendant, set in sterling silver. Approximately 2.5" total length with bail. Agate is opaque white in center, with a natural crease, and more translucent white at edges. Held by four prongs. Blue topaz is light aquamarine-blue, oval with facets, set at a slight angle to the top of the agate. Not from Lux Divine, that's just the box I found to display it in. No maker markings I can see.
