=-Geneve-Blozzo-=8月8日 Diamond ColorActing as a prism, a diamond can divide light into a spectrum of colors and reflect this light as colorful flashes called fire. Just as when looking through colored glass, color in a diamond will act as a filter, and will diminish the spectrum of color emitted. The less color in a diamond, the more colorful the fire, and the better the color grade.

But many diamonds have inclusions — scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. The Gemological Institute of America and American Gem Society Laboratories use a detailed system of rules and standards to summarize the number, location, size, and type of inclusions present in a diamond.

It's fairly common to confuse a diamond's cut with its shape. The cut describes a diamond's light performance, dimensions and finish. Shape refers to the overall outline of the diamond when viewed from the top. Round is far and away the most popular diamond shape, followed by squared shapes such as princess, Asscher, and emerald.
The Round The round brilliant cut diamond is by far the most popular and most researched diamond shape available today. For almost 100 years, diamond cutters have been using advanced theories of light behavior and precise mathematical calculations to optimize the fire and brilliance in a round diamond. In addition to being the most popular and researched shape, a round diamond will typically give you more flexibility in terms of balancing cut, color, and clarity grades while still getting the fire and brilliance you want.
The Princess This is the most popular non-round diamond. Its beautiful brilliance and unique cut makes it a favorite for engagement rings. The princess has pointed corners and is traditionally square in shape. When choosing a color grade, consider that while the price of a J-color non-round diamond is exceptional, color may be slightly visible in its corners. Also, princess-cut diamonds can vary greatly in how square or rectangular they are. This will determine what the diamond will look like when viewing it from above. Here are length-to-width ratios for princess-cut diamond shapes that are pleasing to the eye. 
For a princess diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10.
The Emerald What makes this shape different is its pavilion, which is cut with rectangular facets to create a unique optical appearance. Due to its larger, open table, this shape highlights the clarity of a diamond. If you choose an emerald-cut with a lower clarity grade, such as SI, be sure to review the clarity plot on the diamond certificate. Also, emerald-cut diamonds can vary greatly in how rectangular they are. If you'd prefer an emerald cut with a squared outline, look for an Asscher-cut diamond. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. 
For the classic emerald-cut shape, look for a length-to-width ratio between 1.30 and 1.40.
The Asscher This beautifully unique shape is nearly identical to the emerald-cut, except that it is square. Also, this shape has a pavilion that is cut with rectangular facets in the same style as the emerald-cut. If you choose SI-clarity be sure to view the clarity plot on the diamond certificate, because this shape highlights the clarity of the diamond. When choosing a color grade, consider that while the price of a J-color non-round diamond is exceptional, color may be slightly visible in its corners.   The Oval The oval diamond has beautiful brilliance that's similar to a round diamond. Oval diamonds are also very popular as their length can accentuate long, slender fingers. To find the dimension of oval you want, look for the length-to-width ratio in our interactive diamond search and on each diamond's detail page. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. 
For the most traditional oval diamonds, look for length-to-width ratios between 1.33 and 1.66.
The Marquise The shape of a marquise diamond can maximize carat weight, giving you a much larger-looking diamond. This brilliant-cut diamond looks beautiful set with round or pear-shaped side stones, and the length of the marquise makes fingers appear long and slender. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. 
For the most traditional marquise-cut diamonds, look for length-to-width ratios between 1.75 and 2.25.
The Pear This brilliant-cut diamond is also called a teardrop for its single point and rounded end. The unique look of the pear shape helps make it a popular choice for a variety of diamond jewelry. If you choose an elongated pear shape, the length of the diamond creates a subtle slimming effect on the fingers.   The Radiant
Trimmed corners are the signature of this diamond, and they help make the radiant-cut a popular and versatile choice for jewelry. A radiant-cut looks equally beautiful set with either baguette or round side-diamonds. Radiant-cut diamonds can vary in their degree of rectangularity. To find the dimension of radiant you want, look for the length-to-width ratio in our interactive diamond search and on each diamond's detail page. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top.
For a radiant diamond shape that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.10.
The Cushion This unique shape has been popular for more than a century. Cushion-cut diamonds (also known as "pillow-cut" diamonds) have rounded corners and larger facets to increase their brilliance. These larger facets highlight the diamond's clarity, so if you choose an SI clarity grade, be sure to review the clarity plot on the diamond certificate. Cushion-cut diamonds are available in shapes ranging from square to rectangular. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. 
For a cushion-cut diamond that is square, look for length-to-width ratios between 1 and 1.05. If you prefer more of a rectangular shape, look for length-to-width ratios greater than 1.15.
The Heart The heart is the ultimate symbol of love. The unique look of the heart-shaped diamond helps make it a distinctive choice for a variety of diamond jewelry. When choosing a color grade, consider that while the price of a J-color heart shaped diamond is exceptional, color may be slightly visible in its corners. The length-to-width ratio will determine the diamond's outline, or what it will look like when viewed from the top. 
For a more traditional heart-shaped diamond, look for length-to-width ratios between .90 and 1.10.
Credit: Blue Nile Jewelry Anniversary GiftsAnniversary is a special day which celebrated annualy... It is also an important thing for the economy as the main thing of an anniversary is a gift Most people are familiar with the traditional materials list that good etiquette requires us use as a guide when selecting a gift to commemorate a wedding anniversary. If you are like most people, you might find it a bit challenging to convert the materials on the list into an acceptable gift idea. There may be more choices available to you than you realize. Do you know that an updated "modern" gift list is available which is becoming more and more popular? This article touches on the history of the traditional list, highlights the differences between the modern and traditional lists, and helps you decide which is right for you. Parts of the traditional list have existed since medieval times. Historians can trace the origins of silver and golden anniversaries to medieval Germany, where garlands made of these metals were presented as gifts for the 25th and 50th years of marriage. The rest of the list may not be as traditional as you think. I was surprised to learn that the traditional list, as we know it today, did not exist until 1937. In that year, the American National Retail Jeweler Association published a list, which associated a material for each Anniversary up to the 15th year and then each fifth year after that up to the 60th Anniversary. The following is the materials list from 1937, through the 60th year: * First - Paper The modern anniversary materials list presents us with a contemporary, easier to use alternative. The modern list has no clear beginning, but like the original, each year's gift is more precious than the last. This arrangement is intended to honor the longevity of the commitment. The new list retains the spirit of the traditional list, but loses the some of the sense of etiquette in the original. Although more convenient, the modern list sacrifices the thoughtfulness previously required to make a good gift from the more mundane materials on the old list. However, the modern list is more extravagant (expensive) than the original, which in some cases may be more appreciated than a thoughtful but humble gift from the traditional list. The following is the widely accepted modern list, through the 60th year: * First - Clocks For most couples, I recommend using the modern list. When selecting a gift from the modern list you have the benefit of more specificity, for example a desk set is much more clear than copper/wool. With the modern list, you won't risk insulting your spouse by rewarding 10 years of companionship with a pitiful tin or aluminum gift. Believe me, she won't be satisfied with the excuse of tradition. Also, good luck finding the ivory candlesticks for year 14! Unless you really enjoy the creative challenge of using the traditional list, try the modern list this year. Credit: Slade Hartwell How to Choose Your DiamondWhen selecting a diamond earring set, it is important to have an understanding of the 4 C's. But what are the four C's and what in the world do they actually mean? Here is a brief explanation of clarity, cut, color, carat weight and what they mean when you are picking out diamond earrings.
1) The Clarity of a Diamond. Out of the four C's this is probably the most difficult for an ordinary person to distinguish when looking at a diamond earring, but is possibly the most important. The clarity determines how brilliant or dull the diamond will be depending on how much light can reflect without the disturbances of flaws (also known as inclusions). There are 12 different symbols that are used to describe the clarity of a diamond. An 'F' denotes that the diamond is flawless while at the other end of the spectrum, an I3 explains that a diamond has obvious flaws that are easily seen with the naked eye. The ten grades in between these two describe how easily flaws can be seen and with what type of magnification. 2) The Carat Weight of a Diamond. While usually thought to explain size, the carat weight of a diamond actually is a measurement of the weight of diamond. One carat is equal to 0.2 grams or 0.007 of an ounce. It is therefore, not a measure of quality but a measure of quantity. The larger the diamond, the more valuable since larger diamonds are more rare than smaller ones. It is also important to remember that just because one diamond maybe double the weight of another diamond doesn't mean that the diamond earring will double in price. The price of diamonds rises exponentially. 3) The Cut of a Diamond. The term 'cut' for a diamond has two different connotations. The more basic of the two, is the shape of the diamond. Diamonds come in various shapes such as the round, oval, emerald, pear, heart, and marquis. While these cuts are easy to distinguish and to choose from, the more difficult cut to decipher is the different angles, proportions, symmetry, finish and polish of the diamond earring. This plays a large part in the beauty of the diamond and how well it will reflect light. If it is a shallow cut light will be lost from the bottom while if it is a heavy cut light will be lost from the sides. The goal is to get a fine cut where no light is lost. The quality of the cut depends on the jeweler. A diamond is usually cut with 58 different facets. If the cuts are mathematically correct and precise, then the diamond earring will be able to reflect light with brilliance. 4) The Color of a Diamond. The color of the diamond helps determine the value of a diamond whether it is completely without color or is tinted yellow. There is a scale from D-Z that grades the color of the diamond. The letter D is used for diamonds that are completely clear. Before assuming that the farther along the scale you go less valuable the diamond is, think again. Within the scale there are canary yellow, blue, pink, and red diamonds that are considered to be very precious. For example, the rare and valuable Hope Diamond is not clear but blue. Each of the 4 C's plays a large part in the value of a diamond all must be taken into account when purchasing your diamond earring set. After gaining a better understanding of these important factors that affect the value of the diamond, decide what is important to you so that you can find yourself the perfect pair of diamond earrings. 8月2日 Options Your heart keeps saying it's just not fair,
