How does one define a Best Diamond ?
A typical diamond FAQ is “where do the best diamonds come from”. There is no single quick answer, apart from the slightly facetious “in the ground”. We are in process of preparing a more complete answer which will be linked from here when ready.
What are Qualities of the Mineral – Diamond ?
Diamond is the ultimate gemstone, possessing few weaknesses and much strength. It is well known that the diamond is the hardest substance found in nature, and it is four times harder than the next hardest natural mineral, corundum. But even as hard as it is, it is not impervious to damage. Diamonds have four directions of cleavage, meaning that if they receive a sharp blow in one of these directions they will cleave, or split… It has a broad color range, high refraction, high dispersion or fire, very low reactivity to chemicals, rarity, and is extremely hard and durable.
Glittering in Colors
Of all the precious stones, the most valued and most adorable in the world of gems are called ‘The Big Four. Red, blue, yellow, green… if you love glittering radiance, nature’s treasure trove offers endless choices of color stones. Asides from diamond, the King of gems, the other three are emerald, ruby and sapphire. These gems come in a variety of colors, sizes and quality, and a minor difference in certain qualities might make a big difference in their price tags.
What do you mean by Amsterdam?
Amsterdam, was a major diamond cutting center in the nineteenth century, but lost almost all its gem cutters to Antwerp, due in part to strict working conditions imposed on the Dutch diamond-cutting factories by labor unions in the prewar years.
What does the Acronym of Diamond stands for?
Acronyms of D.I.A.M.O.N.D. include Defense Intrusion Analysis & Monitoring Desk, Development and Integration of Accurate Mathematical Operations in Numerical Data-Processing, and Dow Industrial Average Model New Deposit Shares.
What is Diamond Wheel grit?
Diamond Wheel grit refers to diamond abrasive used in precision grinding wheels, honing tools, polishing tools for the machining of non-ferrous materials. These tools are used extensively in industry to machine a wide range of materials including glass, tungsten carbide, ceramics and stone. The tools vary in size from large grinding wheels to the small drills used by dentists. Element Six produces a range of diamond wheel grit products under the PremaDia product name. PremaDia products are available in sizes from 60/80 US mesh to 325/400 US mesh.
What is Ballerina Setting ?
One of the classic multi-stone ring designs, the ballerina, derives its beauty from the placement of tapered baguettes which flow around a center stone to form a tutu, that short flared worn by ballet dancers. There are ballerina rings in which baguettes are set in an undulating curve that literally emulates the tutu skirt of a dancer.
What is BHP Billiton?
The second most active diamond prospecting company after De Beers. Owns the Ekati mine in Canada, producing 4% and 6% of world’s diamonds by volume and value respectively. Markets using Canada Mark brand name.
Define meaning of Alluvial?
Many diamonds are sourced from alluvial deposits in existing or previous river beds. Alluvial diamonds are usually of gem quality, probably because lower grade stones would have been damaged or destroyed.
What is Saw Grit?
Diamond abrasives ranging from 16 through to 80 US Mesh are often referred to as Saw Grit. The extensive range of synthetic and natural Saw Grit diamond abrasives produced by Element Six have been developed primarily for tools used in the processing of stone, construction and geological applications. Typical work piece materials that are sawn, drilled and textured with such diamond tools include; granite, marble, slate, limestone, sandstone, plain concrete refractory brick, ceramic tile, glass and polymer composite.
What is palladium?
Palladium is one of the hottest new metals and sister metal to platinum. It is a platinum group metal, it is considered a precious metal, and it has premium white color that will not fade and does not need rhodium plating. It is nickel free, tarnish resistant and more durable than white gold. It has the look of platinum, and the cost of gold.
What is Metal Stamping?
Jewelry may be made by Stamping. Stamping is generally referred over lost wax casting for jewelry where the design permits, most particularly for cuff bracelets where the strength and uniformity of the metal reduces breakage when the bracelet is bent. Stamping is not feasible with undercut designs. Our sterling silver cuff bracelets, such as the Lovebirds Bracelet and Dragon Bracelet, are all stamped, as are some of our pendants and earrings.
What is a Lost Wax Casting?
Lost wax casting is preferred when an item has deep or undercut indentations or a highly variable thickness. Detail may be reproduced well. Some variation in weight, detail and polish is normal as the result of differences in temperatures at the several stages of the process and in the hand work involved.
How does Diamond Fluorescence affect price?
The impact of blue fluorescence on price depends on its notice ability. For some higher color stones, fluorescence gives the stone a milky white appearance, which greatly lowers value. Fluorescence often adds value to lower color stones as it gives the stones a whiter, brighter appearance.
What is synthetic Saw Grit?
Synthetic saw grit can be manufactured using techniques which emulate the natural geological growth of diamond. This involves using a high pressure/high temperature (HP/HT) synthesis process, which converts the soft graphite carbon into the very hard crystalline form of carbon – diamond. The synthetic saw grits from are grouped into three Series: the SDB 1000 Series, the SDB Plus Series and the DSNAD Series. Each Series is differentiated by its particle strength, particle crystallinity and wear mechanism, as defined by the Saw Grit Indicator System.
What is Diamond-like Carbon or DLC?
Diamond-like carbon or DLC is an amorphous hard carbon. Since the early 1970s, DLCs have been produced for a variety of practical uses. In particular, the “Diamond-Like” term was coined simply to describe its very high indentation hardness, which is between that of CBN and the soft facets of natural diamond and is very dependent on the synthesis technique used to form it. A consequence of their amorphous structure and the deposition process used is that DLC layers can contain large amounts (up to atomic 40%) of hydrogen.
Is a diamond a good investment?
The answer depends on whether you are investing in the diamond itself, or in what a diamond represents. Diamond prices have been steadily increasing for the past 20 years, and diamonds tend to hold their value. As a timeless and beautiful gift to yourself or as an emblem of your commitment to another, a diamond is an excellent investment.
What is a “clarity enhanced” diamond?
Some diamonds with surface reaching factures are filled with a glass-like compound to make them look better. This process merely improves the appearance of the diamond compared to what it would look like without the treatment. It’s a legitimate process but jewelers are required by law to disclose whether a particular diamond has been treated.
What is “laser drilling”?
Laser drilling is used to improve the appearance of diamonds with dark imperfections. The most common procedure uses a fine laser beam to tunnel into a diamond and burn the existing inclusion, which is further lightened with acid. As this process is stable, all labs will grade laser drilled diamonds and indicate the process on their report.
What are Real Diamonds ?
Real diamonds are worth their weight in Gold. They usually maintain a consistent value. It seems, if anything they are continually increasing in value. It is like gold and silver in that it is usually increasing in value. Plus the Fire, the Brilliance, the Luster and Sparkle of a real Diamond cannot be compared with any other stone for its magnificence.
