The Christmas Star
The Christmas Star was commissioned by De Beers and placed on top of their 1994 Christmas tree, which toured 20 cities in Japan and was seen around the world on television including CNN.
It was developed in order to provide retailers an alternative marketing concept that would allow diamonds to be used in decorative pieces for the home, as opposed to jewelry. It is also one of the earliest examples of a branded diamond, first cut and polished by Fancoldi in Israel.
Each Christmas Star diamond also came with a registration package that would allow the owner to name a real star in the Milky Way Galaxy, a service that still exists today but which is no longer tied to a diamond purchase. These diamonds were somewhat unique in that they were priced and sold in terms of their millimeter dimensions, not by their carat weight.
The Christmas tree
George Saltzman, a talented inventor and diamond professional, first developed the Christmas Tree cut over 20 years ago. Most Christmas Trees were developed from broken or irregular triangular rough stones, allowing cutters to achieve higher yields than might otherwise be possible.
The finished stone might start off as a triangle, and then have grooves cut into the sides to resemble the familiar angles of a Christmas Tree. The cut was more commonly used in green and blue gems like topaz and emerald, keeping with the traditional colors associated with Christmas and winter. There were also stones supposedly produced from irradiated green diamonds. The Christmas Tree is reportedly still being cut in extremely limited quantities in Israel, but is mostly extinct and dismissed as a novelty of sorts.
