Diamonds are usually purchased for special occasions such as marriages, birthdays, anniversaries or as an expression of love. At Netaya Jewelry we understand that many people buy only one diamond in a lifetime, so we want your purchase to be one made with extreme care. To determine the quality and value of a diamond, 4 characteristics must be considered, they are known as 4's of diamonds:
Diamond cutting is a fascinating art. Not only does it require great skill and precision in knowing how to cut, but also where on the stone to cut. Rough diamonds are expensive, so the diamond cutter must save as much weight (carat weight) as possible from the rough, and at the same time create a beautiful gem. In addition to the type of cut, the proportions of the cut are critical to obtaining the maximum brilliance and fire from a diamond. The beauty of a diamond is its ability to capture light and return it to the eye, reflecting a beautiful rainbow of colors. When a diamond is cut to good proportions, light is reflected internally from one facet to another and dispersed through the top of the stone. Most gemologists consider cut the most important characteristic, because even a perfect diamond with a poor cut will have dulled brilliance. Clarity
A reduction in brilliance is also caused by the number of inclusions in the stone. A major factor in determining the value of a stone is the presence or absence of inclusions, i.e., the clarity of the stone. Inclusions are natural mineral compounds that developed when the diamond was formed millions of years ago. Minute black carbon specks, air bubbles or feathery white marks became trapped inside the diamond. These inclusions are commonly referred to as imperfections or flaws - terms which denote negative connotations. There are two types of inclusions: external and internal. External characteristics are called blemishes. Most of these can be removed by minor re-polishing. However, this is not true in all cases due to the difficulty of re-polishing, or the risk that attempting to remove an existing blemish a new one may be introduced. Internal characteristics are called inclusions, and there are many. The most common terms are knots, clouds, pinpoints, feather (also called fracture or break). These terms accurately describe the appearance of the internal inclusions. In determining the clarity grade, the size, position and number of inclusions are considered, and bear in mind that nearly all diamonds contain inclusions.
A diamond is the only gemstone in which the absence of color makes the stone more valuable. Diamonds range from colorless (pure white) to a degree of yellow tint- the less color the more valuable. Of all the factors affecting the value of a diamond, color is the most subjective. Color differences from one grade to the next are so subtle only a trained eye can tell them apart. However, for the purposes of establishing value, diamonds are graded according to their body color. The chart below represents the color scale. At Netaya we sell diamonds ranging from G to L with the majority being near colorless.
There are many factors which affect the perceived body color of a diamond, e.g., the color of the room in which it is viewed, the type of lighting, and the mounting of the stone. The color of the metal used in jewelry will affect the appearance of the diamond body color. Colorless and nearly colorless diamonds may appear slightly yellowish in yellow gold. Therefore, Netaya diamonds set in yellow gold have white gold or platinum prongs. At Netaya we offer mountings in 14k and 18k gold in both white and yellow color, as well as, Platinum which is considered the ultimate metal for mounting diamonds. Carat Weight
