Natural Diamond Guide - What You Should Know Before Buying Diamond Jewelry

If you're looking to purchase natural diamonds either traditional white or the increasingly popular colored diamonds, you may have some questions about what makes a quality diamond.
In this article we will answer some of the more common questions relating to natural colored diamonds so you will be better prepared to buy anything from an engagement ring to a pair of diamond stud earrings.
By acquiring some knowledge about diamonds and what makes them valuable, you'll be in a better position when it comes time to select and purchase a diamond of your own.
What is a Diamond? Diamonds are carbon molecules arranged in a cubic or isometric matrix.
A cubic crystal arrangement is created when the crystal forms outward at the same rate during its growth creating a perfect octahedral shape.
Diamonds are extremely hard (10 on the Mohs scale of hardness) and are very resistant to scratches.
Diamonds are also resistant to acids like hydrochloric and sulfuric acids and can withstand heat of up to 720 degrees Celsius.
What are the Four C's? The four C's are the categories by which natural colored diamonds are graded.
The four C's are: * Cut - The cut refers to the reflective qualities of the diamond, not just the shape.
The cut determines the natural colored diamond's brightness.
The angles that are cut along with the finish are the determining factors of a diamond's ability to reflect light.
Some believe the cut is the most important of the four C's when it comes to a diamond's quality.
* Clarity - The majority of diamonds are not perfect and have some flaws, called inclusions within them.
The clarity grades the nature of these inclusions.
* Color - Natural diamonds are graded for their lack of color.
The whiter, or clearer the diamond the more valuable it is.
(Note, this does not apply to "fancy" colored diamonds which are specifically graded on their color.
) * Carat Weight - The carat weight refers to the size of the diamond.
Larger diamonds are more rare and are therefore more expensive.
What is a Certified Diamond? A certified diamond is a diamond that has been graded by an accredited gem lab.
The certificate guarantees that the diamond has all the qualities described in the report.
Diamonds can be certified either by the Gemological Institute of America or American International Gemologists.
When you buy a certified diamond it makes shopping a bit easier.
You can more easily compare diamonds that have the same quality certifications against each other to find a truly good value.
When they are not certified, it's difficult to compare since the individual qualities will be difficult to determine.
Is it Safe to Buy Diamonds Online? In general, it can be safe to purchase a diamond online, but it is good to take precautions if you choose to buy this way as there can be a lot of fraud in this industry.
These are a few things to take into account before buying online.
First, be sure that the diamond you're purchasing is certified.
Since you won't be able to examine it in person, you would be wise to be sure that there is an independent validation of the quality of the gemstone.
Second, find out the method of shipping that will be used and make sure that the shipment is insured in case of loss.
Third, find out what the return policy is in case you are not satisfied with the diamond or the setting once you receive it.
