ABSTRACT:
BRIEF DESCRIPTION OF THE INVENTION
The present invention relates to a Multi-Faceted Combined Gem Stone. With a square top and round bottom. The Multi-Faceted Gem Stones have various characteristics that distinguish them from other gemstones.
Generally gem stone cutters try to achieve a good combination of brilliance and deception. The basic steps for a gemstone that is known to diamond cutters is blocking, including all shapes.
Blocking the round stone: step 1—you are cutting four top corners and four Basils at the top. In four corners at the bottoms in four pavilions. Then we make the brilliand daring facets at the top and bottom totaling 56 facets.
Emerald Cut is blocked with 3 step cuts at the top corners parallel with the table and the girdles, and 3 step cuts at the point. At the bottom corners also 3 step cuts and the same at the points, 3 facets from the girdle break up to the Culet. Totaling 48 facets. And so further all the shapes the marquise the pear shape the radiant and the luceda, are faceted about 48 to 56 facets.
As known for generations for diamond cutters to make a brilliant really alive fire and sparkling is what more calculated facets cuts one varies the other. And that is what I created.
The King David cut with its 104 brilliant cuts makes it the most brilliand and sparkling diamond gem stone ever manufactured.
The Queen Bat-Sheva Cut with its 128 brilliant cuts makes the gem-stone much more flammable fire; much more sunshine with its most brilliant facets.
