Comments:

This is a unique cut and works well with the material. The pavilion of the stone is a modified round brilliant, but the girdle and crown were based on a Double French Star cut. The combination of these two cuts gives this stone character, and a very interesting look.  The gem is more lively than the photos indicate, and the light blue tinge in the stone is rare to find in facet grade Feldspar.  This stone was faceted by Brett Kosnar.

Comments:

This stone was faceted by Brett Kosnar from a high quality piece of rough that he personally hand-selected.  The material is incredibly difficult to find on the market, and even smaller gems with this kind of color flash are few and far between. The stone is essentially a white precious Opal, but when rotated in a strong light, one can see five different flashes of color including red, orange, yellow, green and blue.

This stone displays a gorgeous deep navy blue color, and is uncommonly clean for Tourmaline.  Please note that the stone has a very deep color in person, and does need a good light for the color to really shine through.

Comments:

This cut goes against traditional faceting etiquette, because it does not have a table. Several low angle facets have replaced the table which brings out more brilliance in this stone. This cut also allows for Sphalerite to display some excellent color flash.
