This cut refracts the light inside the gem and reflects light on the outside facets of the gemstone, maximising the stone's brilliance and fire. Gemstones that are transparent are usually made into faceted stones tomaximise their beauty.Flat, polished faces called facets and pointed bottomRefracts light inside the gemstone and reflects light on the outsideUsually transparentYour typical diamond engagement ring stoneUsually in a claw settingGemstone facets made is gemstone facets and proportions must be considered when choosing a suitable setting.

crown must be covered with metal. The gemstone must be set level from all angles. The culet must not protrude below the setting or touch the finger.Faceted stones need to be open on the bottom for the best bounce of light. Rectangular stones with curved sides face a special challenge. The traditional setting technique is to miter the corners and solder them shut. This is very hard to get an accurate fit, especially for stones with curved sides. The solution is to hammer the corners sharp and form the curves with a specialized stake designed for this purpose.Technique to make bazel setting ( faceted gemstone )Use a Sharpie to mark the desired spot to cut. Make sure the metal rim is smaller than the stone. Open the sheet overlap and cut with a 2/0 saw blade. Solder shut with 18K hard using the yellow self-cleaning flux.Bending the solder seam area into a curve makes filing the solder easier. It is much easier to file a curve than a flat area.Truing the rectangular shape on a bezel mandrel is helpful as it makes a perfect rectangle from the imperfect plier bending effort.Check the stone against the bezel blank to see that it fits. If it is too big, cut out a piece, resolder, and reform. The stone should cover about half of the bezel. The hammering of the corners willenlarge the bezel so a good fit is possible.With a B-4 bezel stake, the undercut makes it possible to form the corners and the curved sides. Hammer the corners from both sides, so the metal will move toward making a sharp corner.Make another rim the same way to fit inside the first rim. Check the fit against the first rim, not the stone.Solder the inner and outer bezels together with medium 18K solder. Keep adding solder until the seam is filled.
