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”.
Getting February off to a good start with the February birthstone, amethyst. This is a 18.0 mm, 21.92 ct. round cut with concave facets on both pavilion and crown.
The rough was one of the “ultravolet” amethyst pieces I got from Steve Ulatowski last February in Tucson. Heading to Tucson in a few more days to restock.
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.
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.
I don’t often cut smoky quartz. However, this one was a badly chipped stone that a local jeweler provided so it was a good “preform” use as a starting point for additional experiments with the UT Fantasy machine.
The end result is 22.99 carats, and 23.2 x 14.5 mm.
