  • This videos shows the steps in cutting and polishing a faceted gemstone. I use a facetron faceting machine . For those who do not know, cubic zirconia is a synthetic man made material, not to be confused with the natural gemstone zircon.
    I sell finished jewelry on Etsy.com, my shops name is Gemsbymbk.

    That is a marvelous stone. The excellent cutting job and the high R.I. of CZ really "answers the bell". Very nicely done on the C3 facets... I've never met a faceting machine that "liked" to cut at ten degrees. LOL
    Thanks much for the video!

      Thank you john, yes , ive chipped stones before when cutting at those steep angles, also you can gouge a soft metal lap such as a batt lap too, it happened to me and i was turning it slow- polishing.
      I had a viewer wanting me to cut a large stone from this color cz in this same design but i havent been able to find a piece big enough. I wonder if this design would lose alot of sparkle and brilliance if cut say at around 30 or 35 millimeter in diameter.

      I always cut pavillions using superglue, then switch to epoxy for the crown. I have heard of a method where you press the rough into warm soft wax to make an impression, then coat the wax with superglue, resulting in a very strong bond which is much easier to release when the time comes. Haven't tried it yet.

    If I tried this I'd end up with nothing because there would always be one face that was not exactly the same and I'd keep trying to fix it.

      Sometimes that almost happens to me. The solution is slow down , cut at a slow speed , look vewy closely at the stone, look often.

    You said you were using epoxy to dop the stone, but I see black wax???

      That was a stone where the epoxy failed on the initial dopping so on the 2nd try i used the wax . I dont know why it happened. Thanks for watching.

      50 years ago , a 1 carat synthetic diamond (strontium titanate ?) would cost us in the jewellery trade $200, they were softer & more brittle,slightly higher refractive index than diamond & CZ, but nowhere as good as CZ.The Chinese produce it cheaply ,as they do tools & every thing else these days ..consider yourself spoilt !
