Good cutting requires experience, creativity and modern machinery. We at John Dyer & Co. employ the latest technology to bring you a superior gem. Many cutters overseas use a rather crude method of cutting.
They simply glue the gemstone to a stick and hold it to a grinding wheel using very rudimentary machinery. Such methods cannot consistently produce beautiful gems. We use only modern, accurate faceting machines. We employ gem cutters who know how to bring the best out of a piece of rough. As much as possible,
we try to cut our gemstones without internal flaws or inclusions. This guarantees that you will have a gemstone of which you can be proud.
Good gem cutting requires experience, creativity and modern machinery. Here we share part of the process to help you understand just how much work is involved in transforming gemstones from the original rough to something which can be faceted.
This video about grinding Bolivian Ametrine rough shows one of our processes before the final cutting and polishing of our beautiful gemstones. This first process is grinding the rough clean in preparation for the final orientation of color, preforming and then finally faceting and polishing. This grinding is a long process during which we tried to condense the video as much as possible so you could see how much work goes into creating our beautiful gems but not still have to wait through all the slow parts.
We try to cut our gemstones without significant internal flaws or inclusions and this initial process of grinding the rough is a big part of that effort. This guarantees that when you purchase one of our gems you will have a gemstone of which you can be proud.
