We invite you to learn about the Four C's of diamonds, however we also want to encourage you to come by and speak to Mr. Lyons. Mr. Lyons has repeatedly stated that diamonds are his first love, other than his wife, Denise. He believes that diamonds should speak to you with their undeniable beauty and to achieve this you must have an excellent cut diamond. This process has been modified over the years, but none can match the precision of the IDEAL cut diamond. An IDEAL cut diamond has specific proportions and strict parameters that were first discovered by Marcel Tolkowsky in 1919. This blue print is still used to produce a diamond with maximum brilliance and maximum fire that results from varying combinations of crown and pavilion angles.

Your Guide to the Four C's

Diamonds are the most popular and well known of any gems. Diamonds are found in the earth's core, more than 93 miles below the surface of the earth. They are made of carbon and are the hardest substance known to man. Once a diamond has been formed in the Earth's upper mantle it may remain there for years before being carried to the surface by molten rock in a little as a few hours. Near the surface the molten rock erupts as an explosive and hardens into a rock known as kimberlite in which the diamond is embedded. Diamonds are known for being the best conductor of heat, they have a very high refractive index and dispersion to have brilliance and fire of a well cut stone. When light strikes a diamond some is refracted off the surface but the part that enters the stone slows down and is bent from the original path, which is called refractive index. This is extremely high in diamonds compared to most gems. 

Diamonds can come in a variety of colors and shapes. The most common colors are white, blue, green, yellow, black and pink. Red is the rarest of all. The shapes include round, emerald cut, princess cut, marquise cut, oval, heart shape, pear shape, and trillion cut. 


Color

 Most diamonds, although appearing colorless, actually have slight tones of yellow or brown. As these tones become more apparent, the rarity and the cost decrease.

Diamonds are found in a range of color, from white, slightly yellow, brown, and bright yellow. White diamonds, those with the least amount of color, are most highly valued and are priced accordingly. Lyons Jewelers' carries diamonds with the highest grades of color because the slight yellow or brown tones in low grades of color can be noticeable to the unaided eye. If you'd like to learn how to save money and get excellent color by choosing your diamond wisely, stop by our store.

 

Clarity

Practically all diamonds contain naturally occurring internal characteristics called "inclusions". The size, nature, location, and amount of inclusions determine the diamond's clarity grade and affect its cost.

Diamonds that are completely free from internal flaws, or inclusions, are very rare and highly-prized. Clarity grades are based on the number, location, size, and type of inclusions found in a diamond. Lyons Jewelers' diamonds have some of the best clarity ratings available. Come visit our store to learn how to choose the best grade of clarity for your diamond at the best price.

Cut

When a round brilliant diamond has been cut to "IDEAL" proportions by a master cutter, it is a splendor to behold.

The Ideal Cut Diamond describes a round, brilliant diamond that has been cut to exact and mathematically proven proportions. Its symmetry, with 58 exactly placed facets, produces the ultimate in luster and beauty.

When a diamond is cut to the Ideal proportions, all of the light entering from every direction is totally reflected through the top and disperses into a stunning display of sparkling flashes and rainbow colors. One unique advantage of the Ideal Cut is that its sparkle can mask otherwise noticeable inclusions.

The cut, or geometric proportions, of a diamond has a tremendous affect on the sparkle of a diamond. Even if the diamond has perfect color and clarity, a poor cut will make a diamond look dull and lackluster. Lyons Jewelers' carries only the highest grades of diamond cut, which present the most beautiful brilliance. Learn how to stay on budget and still get a high-quality grade of diamond cut.


Carat Weight

The size of a diamond is measured by carat weight. Since larger diamonds are rarer than smaller diamonds, diamond value tends to rise exponentially with carat weight. Learn more about carat weight and how to balance diamond quality with the size of your diamond by speaking with one of our helpful professionals.

Several factors determine what the cutter will do with the rough diamond. The size and the shape determines the cutters planning. Octahedral or dodecahedral rough is best used for round brilliant cuts. Flattened, elongated or distorted rough is best used for fancy shapes. As you can tell, it takes a well trained cutter to get the best out of a rough diamond.
