In case you are shopping for a diamond engagement ring, you need to understand certain basic properties of diamonds. Sometimes, these simple pieces of information do not reach the common man. Below is a discussion about facts regarding diamonds that you need to keep in mind before heading out to buy the best wedding rings.
Diamond Value is Partially Based on the Absence of Color
Diamond color is a critical parameter while buying diamonds. Most engagement rings use diamonds that are almost colorless with slightest tints of brown and yellow. Besides, the more colorless a diamond is, the pricier it would be. The GIA uses a grading system that rates diamonds from D to Z grade. It helps you to assess the precise color of a diamond. In fact, it determines the scale of colorlessness of a diamond. The differences in color can be observed clearly by placing diamonds from either end of the spectrum besides each other.
The Color Grade of a Diamond Should Be Determined by a Grading Laboratory
The differences in diamond color grades could be extremely subtle that they might be undetectable. However, they make a huge difference in the pricing of diamonds. Therefore, it is important to leave this job to a certified gemological laboratory like the GIA. They have the knowledge, experience, and expertise to carry out a comprehensive and unbiased grading.
While evaluating the diamond’s color, the GIA uses a stringent protocol which decides the neutral background and light setting. Besides, there are also rules about the way the diamonds are viewed and held during the analysis. The color determination is done by comparing them to masterstones. These are a set of comparison diamonds with a known status along the D to Z gradient.
Colored Diamonds are Graded and Valued Differently from Colorless Diamonds
The diamonds with color certainly have a special consideration among diamond users. There are colors ranging from orange, pink, purple, brown, green, yellow, blue, gray, black, or red. This does not comprise of diamonds under the normal color range such as slightly brownish, slightly grayish, or slightly yellowish. If the diamonds have a natural color, they are called fancy diamonds.
Fancy colored diamonds are much more expensive than colorless diamonds. This is mainly because Fancy-color diamonds are very rare in nature. It is estimated that only about 2% of the diamonds produced are fancy colored. This justifies the high price of these diamonds.
Treatments Can Enhance Diamond Color in a Major Way
Diamonds subjected to treatments show great improvement in color. If all conditions are the same, diamonds which have been treated are more expensive than those with no treatment. By law, the dealer is supposed to reveal any treatments performed on diamonds. Annealing is one of the prominent processes used to heat and cool the stone in a controlled way. Irradiation and coating are other ways of improving the color of a diamond.
Diamond Fluorescence Has a Very Minor Influence on Diamond Color
Diamond fluorescence is defined as the visible light let out by certain diamonds upon exposure to ultraviolet (UV) rays of the sun, or other artificial sources. If the source of UV light is removed, the fluorescence also disappears.
Many people in the diamond industry believe that strong blue fluorescence has the ability to make a yellow diamond appear colorless upon exposure to UV light from a source like sunlight. This is because the blue color is the exact opposite of the yellow light. Hence, they cancel each other. In rare cases, diamonds with a strong level of fluorescence may look slightly hazy or oily. Only less than 0.2% of the diamonds examined by the GIA are said to have this effect.
Engagement Ring Settings Can Impact the Appearance of Diamond Color
Diamonds have a high reflective property. Their surface resembles an array of tiny mirrors that reflect light. Therefore, it is quite natural that the shank and prongs of the ring influence the color visible on the diamond. White metal like white gold or platinum can enhance the absence of color in a colorless or a nearly colorless diamond. On the other hand, a gold band makes the diamond appear to be of a lower scale in the D-to-Z scale by making it look more yellowish.
Be Sure about Diamond’s Color by Getting a GIA Grading Report
A GIA Diamond Grading Report gives you a detailed report of the diamond’s quality by looking into the 4Cs of the diamond. The report consists of identifying properties like fluorescence and other treatments used apart from the objective color grade present in the diamond.
The above points are usually not known to the public. Make sure you read them before you go on and purchase your diamond for the special occasion.
