Synthetic Diamonds - You know you want some
Meet the Toughest Diamond Cutters You'll Ever Use
The oil exploration business demands speed, durability, and toughness. And there's no place where those three things matter more than where diamond meets rock at the bottom of a hole.
That's why US Synthetic has spent more than a decade perfecting polycrystalline diamond cutters (PDCs) that drill faster and last longer—especially in tough conditions that test the limits of the most durable drilling equipment.
Today, US Synthetic leads the industry in the development and production of innovative, top-quality PDC inserts that meet the highest standards and match the requirements of the most demanding oil exploration and development projects.
This absolute, no compromises commitment to superior quality and constant innovation sets us apart from the crowd and makes US Synthetic your best choice for all kinds of diamond solutions.

All about Diamonds
The word "diamond" comes from the ancient Greek "adamas," meaning unconquerable."Carat," the measure of diamond weight is derived from the Greek "keration," the name for the uniform in weight carob seed.
Cut, color, clarity, and carat are the "4Cs" that guide a jeweler in determining a diamond's value.
"Clarity" refers to a diamond's freedom from internal inclusions such as internal cracks or tiny crystals. A diamond may be termed "flawless" if a trained eye can detect no inclusions under 10-power magnification.
"Cut" refers to the way a diamond is cut and polished, the proportion of the diamond that dictates the maximum amount of light the diamond will refract and reflect, and the diamond's facets.
The term "fancy" diamond means pear, oval, or emerald cut stones.
Red is the very rarest color for a diamond.
Marilyn Monroe's famed comment as the character Lorelei Lee, "Diamonds are a girl's best friend," is a classic. But Mark Twain in "Puddin' Head Wilson's Calendar" said, "It is better to have old second-hand diamonds than none at all."
A carat is divided into 100 points.

How Diamond Drill Bits are Used
Diamond drill bits are usually not used on any other materials. The bit is made of a metal cylinder with a fairly soft steel mount on an arbor. At the open end of the cylinder industrial diamond are embedded.
The segments of the bits are thicker than the actual cylinder wall, so the larger portion of the bit is not rubbing in the hole that is being bored. The sloped slots will help to move the dust away.

Synthetic Diamond FAQ
Synthetic diamond (also known as HPHT diamond or CVD diamond depending on the production process used) is diamond produced in a technological process, as opposed to natural diamond, which is produced by geological processes.
Numerous individual attempts to grow synthetic diamond were documented between 1879 and 1928, but none of them have been confirmed to have produced diamonds. In the 1940?1950s, systematic research began in the United States, Sweden and the Soviet Union to grow diamond using chemical vapor deposition (CVD) and high-pressure high-temperature (HPHT) processes. The first reproducible synthesis was reported around 1953. Those two processes still dominate production of synthetic diamond. A third method, known as detonation synthesis, has recently entered the diamond market. In this process, nanometer-sized diamond grains are created in an explosion of carbon-containing explosives. A fourth diamond synthesis variety, using high-power ultrasonic treatment of graphite, has been demonstrated in the laboratory, but has no commercial use yet.
The properties of synthetic diamond depend on the details of the manufacturing processes, and can be inferior or superior to those of natural diamond; in particular, the hardness, thermal conductivity and electron mobility are superior in some synthetic diamonds (either HPHT or CVD). Consequently, synthetic diamond is widely used in abrasives, cutting and polishing tools and in heat sinks. Its applications as a material of active electronic devices, including high-power switches at power stations, high-frequency field-effect transistors and light-emitting diodes are being developed. Detectors of ultraviolet (UV) light or high-energy particles, made of synthetic diamond, are already used at high-energy research facilities and are available commercially. Because of its unique combination of thermal and chemical stability, low thermal expansion and high optical transparency in a wide spectral range, synthetic diamond is becoming the most popular material for optical windows in high-power CO2 lasers and gyrotrons.
Both CVD and HPHT diamonds can be cut into gems of various colors: clear white, yellow, brown, blue, green and orange. The appearance of synthetic gems on the market created major concerns in the diamond trading business, as a result of which special spectroscopic devices and techniques have been developed to distinguish synthetic and natural diamonds.
