Hexagon prasiolite

Pictured here is a new 5.44 carat, 11.0 mm. prasiolite. As mentioned previously, I find the hexagon cuts attractive. Here the light and dark patterns from the concave facets used on the pavilion of the stone are much more obvious to the camera than to my eyes. The result reminds me of an iris flower (another favorite of which I have too little in my garden.)

Hexagon in Citrine

Another hexagon, this time a bright orange citrine cut from Brazilian rough obtained at the February Tucson shows. (This photo looks too yellow on my current monitor.) It is 9.8 mm. across and is 4.36 carats and is very bright from the row of concave facets on the pavilion.

Hexagon Prasiolite

Prasiolite is a green variety of quartz. The one pictured here is 6.09 carats and is 11.5 mm across. The pavilion of the stone has been cut with concave facets in addition to traditional flat facets. An inclusion in the rough material forced a change in the plan for how the crown was to be cut — and the result was an accidental winner.

Amethyst Hexagon

Here is a freshly cut amethyst. Weight is 9.06 cts. and width is 12.7 mm. Concave facets were used on the pavilion side of the stone while the crown is all traditional flat facets.
