Diamonds can be measured in both carat weight and millimeter. While diamonds are purchased based on carat weight — the standard unit of measurement for loose diamonds — it's important to consider millimeter measurements and ratios to choose the best possible option for your budget. A diamond's millimeter measurement tells you its true size. That's because a diamond of the same carat weight can have slightly different faceting and therefore look larger than a carat weight equivalent.

Most people have heard about the four C's of diamonds through advertisements or direct contact with jewelry salespeople. However, while familiar with the concept, most individuals are a little sketchy on the details. The four C's include diamond carat weight, clarity, color, and cut.

Carat weight is pretty black and white. Diamonds are weighed in carats, which are composed of points. Basically, a half-carat stone is 0. Carat is abbreviated as "ct. Occasionally you may hear the term "four grainer" referring to a 1-carat stone. Each grain is equal to 0. If you think in terms of grams, 1 gram is equal to 5 carats. This metric equivalency provides a level of uniformity anywhere in the world. Due to the limited supply of larger diamonds, the value of a diamond rises disproportionally as the weight of the stone increases.

For example, four 0. The disparity becomes more noticeable as the size and quality of the diamond increases. Diamond Buying Tip: Note that "carat" describes the weight of a stone, not the size. Carat weight and size are fairly uniform from diamond to diamond so a 1-carat round diamond will consistently measure around 6. Colored stones, however, are a different story. Since density varies from one gemstone to the next, shape and dimensions must be specified.

If you are ordering a colored stone for your favorite 1-carat round diamond semi-mount, then you also need to specify 6. Standardized calibrations were created for gemstone and jewelry manufacturing. Clarity is determined by the type, size, number, position, and contrast of inclusions. Contrast is important, because dark inclusions in a diamond are more visible and therefore more distracting from a diamond's beauty than white or gray inclusions.

Plus, if an inclusion is positioned in just the wrong spot, it can be reflected within the stone multiple times, making the diamond appear even less attractive and negatively affecting its clarity even more. Inclusions occur within the stone, while blemishes are external in nature. There are many grading scales used to describe diamond clarity; however, the diamond grading scale used by the Gemological Institute of America GIA is probably the most well known.

The scale can be broken down as follows:. Flawless no inclusions under 10x loupe IF internally flawless, surface blemishes exist VVS 1, 2 very, very slightly included: minute inclusions VS 1, 2 very slightly included: minor inclusions SI 1, 2 slightly included: noticeable inclusions I 1, 2, 3 included: observable inclusions. Diamond grading should always be performed with a power 10x loupe or microscope under proper lighting by a trained gemologist. Inclusions in stones graded I1, I2, and I3 can be seen by the unaided eye.

Diamonds in the I range are also sometimes referred to as imperfect 1, 2, or 3. Diamond Buying Tip: Clarity makes a significant impact on the price of the stone, but when shopping for diamonds, you should remember that clarity does not always significantly affect a diamond's brilliance, and better clarity does not always ensure a more brilliant stone.

While clarity does affect a diamond's brilliance, the stone's cutting largely determines its brilliance. Colorless stones designated D, E, or F command the highest prices. Diamond colors rank in the following groups:.

When grading diamonds, a nonreflective white background should be used. Diamond graders have to be careful about the surrounding environment. Clothing color, lighting, and the color of their instruments may affect the outcome. Diamonds of certain colors are called fancies. These colored diamonds have intense natural colors that in some cases are very rare and command exceptional values. These stones are not color graded using the scale above.

Brown and yellow diamonds are the most common members of the fancy diamond group and have a distinct beauty of their own. Naturally red, blue, purple, and green diamonds are extremely rare and highly sought after by designers and collectors.

Diamond Buying Tip: Color is one of the most noticeable characteristics of a diamond. Most people can notice whether or not a diamond is colorless the most desired. The setting of the diamond can affect the appearance of color. If the diamond is colorless, a white gold or platinum setting will enhance the diamond's whiteness. But if the diamond has a yellowish tint, a yellow gold setting may help mask the yellow tint, making the diamond appear whiter. The breathtaking beauty of a diamond comes from a combination of fire that flash of rainbow colors that comes from within and brilliance the burst of sparkling light.

This dazzling beauty is a direct result of the diamond's cut. The last of the four C's, cut is a little more complicated than just the shape or visible outline of the diamond.

Cut also refers to a diamond's faceting as well as the diamond's symmetry, proportion, and finish known in the trade as the "make". Brilliant: Designed for maximum diamond sparkle, the brilliant cut uses many triangular and kite-shaped facets. Step: Instead of sparkle, a step cut aims to increase a diamond's elegance with fewer facets and more trapezoids and rectangles.

Mixed: A mixed cut combines the step and brilliant cut styles for a uniquely beautiful diamond. All diamonds are cut to certain tolerances designed to maximize the play of light within the stone. If the stone varies too greatly from the accepted standards, light is lost through bottom or sides, reducing the diamond's liveliness and overall beauty.

As a general note, most full-cut round brilliant diamonds have either 57 or 58 facets, depending on the absence or presence of a culet the bottom-most facet or "point" of a stone.

Diamond clarity is the quality of diamonds that relates to the existence and visual appearance of internal characteristics of a diamond called inclusions , and surface defects, called blemishes. Clarity is one of the four Cs of diamond grading, the others being carat , color , and cut. Inclusions are solids, liquids, or gases that were trapped in a mineral as it formed. They may be crystals of a foreign material or even another diamond crystal, or may have produced structural imperfections, such as tiny cracks that make a diamond appear whitish or cloudy.

However, when it comes that time, then you should look out for some diamond chart templates that can help you to know what you are looking for. You should be informed about the clarity, grading, and size of the jewels to help make it easier on you when you are shopping to make sure you are getting the best.

In grading diamond clarity, the GIA considers the number, size, color, reflectivity, and position of every flaw visible under 10x magnification.

Чип, который он должен был припаять, упал ему на голову. - Проклятие. Телефон звонил не переставая.

Беккер снисходительно покачал головой: - Иногда все выглядит не так, как есть на самом деле. Лицо немца стало белым как полотно. Беккер был доволен. Ложь подействовала: бедняга даже вспотел. - Че-че-го же вы хотите? - выдавил он заикаясь.  - Я ничего не знаю.

 - Она встряхнула волосами и подмигнула. - Может быть, все-таки скажете что-нибудь. Что помогло бы мне? - сказал Беккер. Росио покачала головой: - Это. Но вам ее не найти.

What are "Pointers"?

Беккер усмехнулся, представив это зрелище. - Может быть, американка? - предположил. - Не думаю, - сказала Росио.  - На ней была майка с британским флагом. Беккер рассеянно кивнул: - Хорошо.

В перерывах между сигналами Сьюзан выкрикнула: - Ты - Северная Дакота, Энсей Танкадо передал тебе копию ключа. Он нужен мне немедленно. - Ты сошла с ума! - крикнул в ответ Хейл.  - Я вовсе не Северная Дакота! - И он отчаянно забился на полу. - Не лги, - рассердилась Сьюзан.
