Amethyst and Spinel Brooch

My AGTA Spectrum 2011 Entry. Elongated pear shape cabachon is natural untreated Amethyst from Bolivia. Faceted spinel outline the center stone.  I made an 18karat enhancer to wear as a pendant. Completely hand fabricated in 18 karat gold and platinum.

Reverse view shows the platinum settings and the heavy solid 18karat wire that encircles the settings. The amethyst weighs 25 carats. 

I purchased the amethyst at the 2010 GJX in Tuscon from an independent cutter.  The spinel have such a beautiful range of blue and lavender color. Together the combination makes a dramatic color statement.
