In "The Gentleman, The Beauty," Marilyn Monroe sings "Diamond is the best friend of a woman," becoming a classic line in the golden age of Hollywood movies. However, when the first diamond selection will always be complicated logo and parameters get confused, and sometimes buy the hand though their own heart water, but the price is not high, it may be cost-effective to give up their favorite diamond ring, so dilemma. Today teach you the skills to choose diamonds, so that you no longer feel helpless. Weight more than 50 minutes is the mainstream According to the survey data shows that the choice of weight in 50 or more accounted for about 43%, followed by 1 carat weight, this ratio is about 27%. Therefore, more than 50 points to 1 carat can be described as the most common and most popular choice. Weight of this piece, buy a diamond ring actually has a little trick, that is, choose the 70 or 80 points, the highest cost. Because some people think that the price of 1 carat is too expensive, but can be found by comparison, 70,80 points and 1 carat diamond ring size difference is not large, the price is a difference of a grade. In addition, the first set before buying carats, at least have a rough idea. Clarity lower anyway Although the clarity of 4C is one of the important indicators, but when the election drill do not be fooled to choose the highest level, the determination of clarity need to use a 10 times magnifying glass from the table to observe the naked eye is hard to see of. Chroma I color is better The difference between the chromaticity is very large, but generally as the main drill on the diamond ring, the chromaticity is preferably above I color, that is, D, E, F, G, H, I. I color is not recommended below, because the naked eye can see the yellow. E, F, G color more recommended to buy. Cut the highest level of importance The shiny diamond we saw was actually an obscure gemstone that was cut and polished to reveal the shimmer we saw. Therefore, the cut is a very important one. The quality of the cut directly affects the diamond's fire color, determines the pros and cons of a diamond, cut fine diamonds, emitting brilliant dazzling light, cut bad diamonds, the edge does not seem sharp, dim reduction. The same size, the same color level, the same clarity of diamonds, due to the quality of the cut, its price can vary by several times the giant. Now diamonds are basically computer-cut, so under the standard cut, the weight of the diamond and the waist diameter has a fixed ratio. " "Eight arrows and eight hearts" may not be like In the diamond cut big fuss about "eight arrows eight heart" this deeply rooted concept. The so-called "Eight Arrows and Eight Hearts" effect is that the top of the diamond is overlooked from above the top. You can see the eight arrows with the same size, bright light and symmetry, and the perfectly symmetrical and full eight hearts from the bottom of the diamond. "Judging the quality of the diamond cut is nothing more than judging from the symmetry and the ratio of these two aspects of the eight arrow eight heart cut is to highlight the symmetry, cut a good diamond must have eight arrows eight heart.But only eight arrows eight Heart, good symmetry, but not necessarily cut like .If the cut out too high or too short, it certainly is not good gloss, so there are eight arrows and eight heart is not necessarily a good cut. Preservation round the best Traditional round diamond is the best value. The reason why the diamond drilled diamond is more expensive than the special shape is because the round diamond in the rough cut when the loss rate of up to 47%, after cutting out the brightest diamond only 53%, shaped diamond after cutting the carat weight can be retained 55% -60%. Diamond blank with tetrahedron or octahedron, if used to do heart-shaped or drop shaped shaped drill, the production rate of up to 50%, and if used for round drilling, the production rate of only about 30%. High-profile shaped diamond, indicating that it saves material, the price is about standard Burn about Bacheng.
