Quality Diamond Blade Manufacturer

Wednesday, May 5th, 2010

There are many different diamond saw blades and components to choose from. Each diamond saw blade and their components are made specifically to cut through certain harsh materials. Some are made to cut through stone and brick. Others are made to cut tile and granite. Make sure you choose the right diamond saw blade for the job.

For instance, what makes a diamond saw blade. Diamond saw blades have key components that make them cut even more efficiently through harsh materials like stone, and brick. Diamond saw blades are made up of the metal core of the blade. The rim of this blade has segmented slots on the end of the blade so that it can hold the segmented diamond crystals in place while the blade cuts through the harsh material. The synthetic diamonds are considered the true “blade”. They act as teeth or claws that grind right through the concrete or the brick. There is also a metal bond called the matrix which holds the diamond particles together while the blade is cutting. As the blade cuts these diamond particles wear away and this matrix keeps the diamonds from wearing faster therefore giving you the most out of the blade. Each diamond saw blade is made different and specific to cut certain types of harsh material.

Diamond saw blades are made to cut through just about anything but they can’t do it alone. In order to cut through the material these blades will need to be spun or driven through the selected material. This is made possible by using diamond core bits. These diamond core bits are basically the drill reinforcement of the diamond saw blade. These diamond core bits act as the transmission of a car. They are made to vary in RPM’s (revolutions per minute) so that the blade will cut through the selected material without it braking. Diamond core bits are crucial when cutting through any harsh material.

Some diamond cut saw blades are made especially to be used to cut harsh materials while applying running water to the diamond saw blade and the material it is cutting. This is very helpful in keeping the diamond saw blades temperature to a minimum. If the temperature gets too hot due to the friction of the blade cutting through the material, eventually it will get so hot that it will warp and then more than likely crack. By applying water to cool the blade while cutting will prevent the blade from warping and cracking and in turn will save you a lot of money in replacements.

Comparing Certified Diamonds

Monday, May 18th, 2009

A certified diamond is a diamond that has been graded, tested and examined by a team of independent fully trained gemologists who then issue a Diamond certificate for that diamond.

Nothing beats seeing a diamond in person to determine the true quality visibly. Diamond appreciation is a very personal thing and different people will prefer different things about different diamonds. At the end of the day all the numbers, certificates and photos in the world mean nothing if you do not like the look of the diamond and it does not sparkle displaying excellent Brilliance, Fire and Scintillation.

Many jewellers and diamond dealers will use terms like Hearts and Arrows, Ideal, Excellent, Russian Cut, Belgium Cut, Fine Make and others to describe their diamonds, with the intention of portraying them as ‘better’ than others. Be wary of accepting these terms as is. They are especially dangerous when assigned to diamonds by the jeweler or diamond dealer themselves without third-party independent support such as a diamond certificate or diamond grading report.

It is important to remain aware of the facts and differences with certification and the process, as well as the different grading standards each diamond grading laboratory offers. While it might be possible to find certified diamonds with the same grade stated on a certificate that appears notably cheaper. As a potential diamond buyer you must be aware that there is no single set of parameters diamond laboratories grade to and every laboratory has a different set of standards. There are no huge bargains within the diamond industry so remember, if a certified diamond sounds too good to be true, it probably is and there usually is a reason.

Not all diamond grading laboratories are as well respected or as stringent in their grading as each other. Diamond grading laboratories should always be independent of any diamond retailers or wholesalers, to avoid any conflict of interests or bias. Diamond Certificates are only of value when they are issued by an independent accredited diamond grading laboratory. Always make certain to identify the source of the certificate or diamond grading report. If you have not heard of the laboratory, it could very well be associated in some way with the store, jeweler or diamond wholesaler itself, and so have a vested interest in aiding the sale.

Just comparing diamonds on a diamond price match policy alone is not nearly good enough you have to visibly compare the diamonds next to each other to truly see which diamond is the better quality diamond.
