The style and design style of the Grand Carat wedding ring is mainly in a simple and atmospheric style. So how do you choose a good and cheap diamond ring? I want to pick out the "affordable" from the low-purity diamonds. Note the following three key points.
1, should try to ensure that the big diamond has the most flamboyant fire.
The clarity of a diamond does not actually affect the fire of the diamond, as long as the cut is maintained. In the evaluation system of “GIA†diamonds, there are many projects related to cutting, but only three are really critical. This is “Cut (cutting comprehensive index)â€, “Pol (polishing index)†and “Sym (symmetric). Sex indicator)". If the customer can guarantee that the “cutting comprehensive index†reaches “EX (excellent)†when purchasing the carat diamond, then even if the other two cutting indicators only have “VG (very good)â€, the guaranteed carat can be guaranteed. The drill has a good fire.
2. Control the color, size and position of the enamel in the diamond.
SI-grade diamonds can clearly contain "micro-small" in the standard. The smaller the ç‘•ç–µ, the lighter the color, it should be the absolute choice. To prevent the ç‘•ç–µ from being reflected and amplified by the light refraction, it is convenient to use the claws for effective hiding during the setting.
3. Be careful not to let the selected carat diamond have a fluorescence that affects the appearance.
Diamonds are fluorescent, white, blue, purple, etc., where the fluorescence is strong, the naked eye can be observed, and the low fluorescence needs to be placed under the ultraviolet light to appear.
The above is a small suggestion for the diamond ring purchase.
