FAQs

What is a diamond made of?
A diamond is made entirely of carbon (just like the graphite in a pencil). But, while graphite is very soft, the carbon atoms in diamond form in such a way as to create the hardest known substance. This special structure allows diamonds to take a superior polish and project more brilliance than any other natural colorless gemstone.

Can a diamond break or chip?
Even though diamonds are extremely hard, they can still be damaged from abuse. Diamonds can scratch each other and all other gemstones, such as sapphires, rubies, emeralds, and pearls. Store your diamonds away from other gems in your jewelry box and don't wear any valuable gemstones while doing hard work.

How should I clean my diamond?
Anything that cuts grease will help remove the build-up of oil and dirt from a diamond. Commercially prepared jewelry cleaner is perfectly suited for this purpose as is dish detergent and a bit of ammonia.

What is a diamond certificate?
Diamond certificates, or grading reports, are independent documents that provide extensive information about the quality of a diamond. Along with carat weight, measurements, clarity grade, and color grade.

What is fluorescence?
For reasons not entirely understood, certain diamonds emit a subtle blue glow when exposed to ultraviolet rays. This interesting phenomenon is called fluorescence. Many light sources including the sun, fluorescent office lights, and "black" lights emit ultraviolet rays. In normal lighting conditions, fluorescence cannot be seen.
The strength of fluorescence is mentioned on the diamond certificates for identification purposes. The appearance of fluorescence in diamonds exposed to strong ultraviolet lamps ranges from very faint (barely perceptible) to very strong (a neon-blue glow). Some diamonds show no fluorescence at all.
A scientific industry study showed that, with few exceptions, fluorescence in diamonds affects neither price nor appearance. There are two exceptions to this rule. In a minute number of cases, diamonds with very strong fluorescence and a special arrangement of clarity characteristics may look slightly "cloudy," but consumers rarely encounter such diamonds. Fluorescence may also have a slightly positive influence on the appearance of certain off-colored diamonds, thereby making them more desirable to own.

Where do these diamonds originate?
Around 2.5 billion years ago, loose diamonds were just coals (pure carbon) heated and compressed into carbon crystals. They were formed very deep beneath the earth's surface and the first known diamonds were spewed by volcanic eruptions. This hardest known mineral on earth mostly comes from South Africa, Russia and Australia.

What is the Rapport diamond report?
The Rapport report provides a list of wholesale loose diamonds prices worldwide as well as news, business issues and fashion trends of diamond wedding rings. The diamond and jewelry industry subscribes to this weekly report which is made as the basis for diamond prices. The prices are listed on tables by color and clarity corresponding to the carat weight.

Who issues loose diamond certificates?
There are five major credible organizations that certify a loose diamond's quality and market value. These are the Gemological Institute of America (GIA), the International Gemological Institute (IGI), European Gemological Laboratory (EGL), American Gemological Society (AGS) and the Diamond High Council of Hoge Raad Voor Diamant (HRD). Their diamond certificates are recognized internationally hence, you can be sure that the diamond you purchase is the real one.

What are the 4C's?
Diamonds are graded and priced according to what is universally referred to as the '4C's'. They are Cut, Color, Clarity and Carat weight. Each is a description of the various characteristics of a diamond. For example, Cut refers to the shape of the diamond, which affects its fire and brilliance. Color refers to the amount of color in the diamond (the less color a diamond has, the more valuable it is, all other factors being equal). Clarity describes the number of natural blemishes and inclusions a diamond has, and Carat Weight is simply a measurement of the diamond's weight (not its size).

Will I be getting the quality that the description states?
You can inspect and compare the diamond you received against the grading report.
