We offer our cutting services to you. There are several variables in the cutting fees, however, the standard service is:
We strive to get the most from each and every stone we cut. You should expect a weight retention of about 20% to 35% on average for well shaped rough. Every stone is different, but we strive to give every stone our best.
Not only do we have a selection of Precision cut gemstones in stock, but we also provide the following services:
we are in the business of serving your needs!

The Art of Faceting
Facets are flat faces on geometric shapes. Gemstones commonly have facets cut into them in order to improve their appearance.
Of the hundreds of facet arrangements that have been used, the most famous is probably the round brilliant cut, used for many colored gemstones. This first early version of what would become the modern Brilliant Cut is said to have been devised by an Italian named Peruzzi.
The art of cutting a faceted gem is an exacting procedure performed on a faceting machine. The ideal product of facet cutting is a gemstone that displays a pleasing balance of internal reflections of light known as brilliance, strong and colorful dispersion which is commonly referred to as "fire" and brightly colored flashes of reflected light known as scintillation. Typically transparent to translucent stones are faceted, although opaque materials may occasionally be faceted as the luster of the gem will produce appealing reflections. Pleonaste (black Spinel) and black Diamond are examples of opaque faceted gemstones.
The angles used for each facet play a crucial role in the final outcome of a gem. While the general facet arrangement of a particular gemstone cut may appear the same in any given gem material, the angles of each facet must be carefully adjusted to maximize the optical performance. The angles used will vary based on the refractive index of the gem material. When light passes through a gemstone and strikes a polished facet, the minimum angle possible for the facet to reflect the light back into the gemstone is called the critical angle.
The basic features of a faceting machine consist of: A motor-driven platen to hold a precisely flat disk (known as "laps") for the purpose of cutting or polishing. Diamond abrasives bonded to metal or resin are typically used for cutting, and a wide variety of materials are used for polishing laps in conjunction with either very fine diamond powder or oxide based polishes. Water is typically used for cutting, and oil or water is used for the polishing process. A system generally called a "mast" which consists of an angle readout, height adjustment and typically a gear (called an "index gear") with a particular number of teeth is used as a means of setting the rotational angle. The angles of rotation are evenly divided by the number of teeth present on the gear, though many machines include additional means of adjusting the rotational angle in finer increments, often called a "cheater". The stone is bonded to a (typically metal) rod known as a "dop" or "dop stick" and is held in place by part of the mast referred to as the "quill".
The dopped stone is ground at precise angles and indices on cutting laps of progressively finer grit, and then the process is repeated a final time to polish each facet. Accurate repetition of angles in the cutting and polishing process is aided by the angle readout and index gear. The exact process of polishing is a subject of debate. A commonly accepted theory is that the fine abrasive particles of a polishing compound produce abrasions smaller than the wavelengths of light, thus making the minute scratches invisible. Since gemstones have two sides, the top being referred to as the "crown" and the bottom the "pavilion", a device often called a "transfer jig" is used to flip the stone so that the opposite side may be cut and polished
