Sunshine for a Rainy weekend

This weekend we are having a welcome wet spell in this part of California. So here is a bit of sunshine for the rainy days.

This is a 12.14 carat citrine which is 15.0 mm in diameter. Concave facets were used on both pavilion and crown to maximize  the “sunshine”.

Citrines with an Angle

Here are a couple more citrines cut with concave facets on the pavilion where the mandrel was at an angle.

The first is 9.77 carats and measures 18.8 x 10.3 mm.

The second is 10.85 cts, 21.1 x 9.0 mm.

Some of the final 2018 rough

Making some progress with the remaining 2018 rough. Three quartz varieties cut with concave facets pavilion and crown.

The largest of these is the prasiolite which is 23.70 cts and is 18.0 mm. in diameter.

Next is a 19.40 cts. amethyst which is 17.0 mm across.

And finally, the citrine which is 5.80 cts and 12.0 mm.

Beginning with an Angle

Here is my first attempt using my new Ultra Tec Fantasy machine for something other than straight on concave facets.

This is a 9.49 carat lemon citrine which measures 14.9 x 10.8 mm.

Uruguay Citrine

Another item that was obtained during 2018 Tucson, this 5.26 carat dark orange citrine is material from Uruguay. The pavilion features a row of concave facets to give it an extra glow. The stone is 9.8 mm wide. And how did that piece of lint get by during the photo session?
