Always insist on a certification from GIA or another trusted gemologist institute to ensure that [url=http://www.1855sacramento.com/woolrich.php]woolrich bologna[/url] you are actually getting what you pay for instead of being ripped off.This site is highly recommended for more information:
When it comes to diamonds there are some of these stones that are much rarer and more valuable than others. Statistics show that each year the total recovered weight of D rated white gems is roughly 900 carats, and that includes mining operations all around the world. This is extremely low, and that is why colorless diamonds with this rating usually go [url=http://www.vivid-host.com/barbour.htm]barbour uk[/url] for high dollars, especially if the size is significant. More than 80% of the stones recovered every year that are not considered white will have a yellowish tint or coloring. In addition there are other issues that affect quality and value.
Most of these gems are milky [url=http://www.achbanker.com/home.php]hollister[/url] instead of offering a clear [url=http://www.davidhabchy.com]barbour sale[/url] surface and incredible clarity. Cloudy areas in the product also affect the way that it looks and what it [url=http://www.1855sacramento.com/moncler.php]moncler sito ufficiale[/url] can command on the market. A number of recovered crystals have defects and fractures that are visible to the naked eye. Canary is [url=http://www.maximoupgrade.com/hot.php]hollister france[/url] the most common colored specimens found, but these crystals can come in every color imaginable. Chocolate, [url=http://www.vivid-host.com/barbour.htm]www.vivid-host.com/barbour.htm[/url] red, orange, pinks, gray, black, green, blue, and [url=http://www.1855sacramento.com/peuterey.php]peuterey[/url] various combinations [url=http://www.rtnagel.com/airjordan.php]jordan pas cher[/url] can be found in the earth, but they are not found very often and it is even more rare to recover an excellent specimen that is clear and defect free.
When colored gems are cut special care must be taken and certain cuts are more effective then others. Both mass and volume will affect the final outcome and appearance, and some cuts may eliminate these while others enhance them instead. Most experts advise against a flat cut [url=http://www.sandvikfw.net/shopuk.php]hollister sale[/url] or a style that is pointed, because this actually causes the item to lose the shading and become more pale. That means a Princess shape or a Trillion design will not be as effective.
The best styles for colored crystals in this family of [url=http://www.ilyav.com/uggpascher.php]ugg pas cher[/url] rocks can include a pear or heart shape, both of which accentuate the unique shade of the rock. Oval is also a good pick, and so are radiant and cushion designs as well.
One thing that you should be very cautious about is diamonds that are synthetically created [url=http://www.mansmanifesto.fr]doudoune moncler[/url] or that are treated to cause then to develop color where none existed before. Both of these methods may be used by unscrupulous or unethical dealers who want to profit big by overcharging for lower quality.
