Swiss & London blue topaz & moonstone pendant

Stamped 925, this beautiful pendant features 2 perfectly spherical rainbow moonstone pieces & several Swiss Topaz specimens, all of which are teardrop shape and 2 small (the smallest round gems that are slightly more green and pale in color). All of the stones that I have mentioned have either been tumbled/ polished to high shine, or are highly faceted, with the exception of the London blue topaz centerpiece.
