Purchasing Diamond Rings is a daunting task for the novice shopper. There is much to learn and consider when comparing stones and making selections. Four characteristics are used to evaluate stones, cut, color, clarity, and carat weight. Cut is the most important, and the hardest to understand.
Getting an education about diamonds will allow you to talk to salespeople intelligently about their stones. Most places will help you with the basics, but much time can be saved by having a fundamental understanding before you get there.
Gems can be cut into various shapes like, emerald, heart, princess, etc, but cut refers also to the way the rough stone is prepared and how much brilliance or fire it gives off. This process will determine the final proportions and how the angles and facets relate to each other. Precision work will be symmetrical. A well polished or finished gem will let the most light through. When all this is done properly it will give that particular gem the most sparkle possible.
These are the hardest substance in nature, four times as hard as sapphires, which are the next hardest. They are also brittle. Careful analysis, sometimes lasting a whole year, is completed before decisions are made about how to cut. There are four cleavage directions. An optimum cutting direction is chosen based on the crystal’s orientation and location of flaws or inclusions. These will be cut away or hidden during cutting, if too much carat weight will not be lost.
When a gem is well cut light enters the flat table at the top and travels down to the pavilion or sloping bottom sides. Here it reflects across to the opposite side and back out the table again. If it is poorly cut light will be allowed to reach the facets and leak out the bottom or sides.
By inspecting the stone with a jeweler’s lupe, the quality of cut will be revealed. Look for light to be reflected uniformly across the whole surface. See if the table is centered symmetrically and its edges form sharp points. The culet, or point on the bottom should be centered, small, and polished without defects.
Next determine if the sides of the square are bowed in, straight, or bowed out. The square can be found by projecting the edges of the octagon shaped table out toward the points of the facets that radiate away from the table. If you study a photo of a diamond for a while you will easily see the square in the middle.
These lines indicate the proportion of table diameter to the stone diameter. If they bend in, the table proportion is smaller, giving more fire, or rainbow color effect. If they are straight, there will be more brilliant white light. When they bow out table proportion is too large, and cut is not ideal. These types of inspections and rules of proportion are good indicators of cut quality in Diamond Rings Toronto.
