Wedding Links 婚礼链接 4C's of Diamond Quality 第4C的钻石品质
Diamonds are graded by four characteristics: cut, carat (weight), clarity, and color.钻石分级的四个特点：剪切，克拉（重量），清晰度和色彩。 All four of these properties determine how much a diamond is worth.所有这些特性确定多少四个钻石的价值。- Cut - What is the proportion of the diamond? 切 -什么是钻石的比例？ Round brilliant diamonds are commonly cut with 58 facets.圆形切割钻石通常以58面。 The better proportioned these facets are on the diamond, the more light will be reflected back to the viewer's eye.在这些方面更匀称的钻石，越光会反射回观众的眼睛。 This is extremely important. When cut properly, the diamond will sparkle more.这是非常重要的。切好后，钻石会绽放。 Diamond cuts are measured by the table percentage, so always ask for it.钻石削减测量表的百分比，所以总是提出要求。 A good table percentage is between 55-60%.一个好的表比例55-60％之间。 Cut also refers to the shape such as: round, pear, and oval.切还提到了形状，如：圆形，梨形，椭圆形的。
If you are having a diamond mounted, write down the measurements of your stone.如果您有钻石的安装，写下你的石头测量。 Measurements never change.测量不会改变。 Measure the stone after it is mounted and verify that it matches the appraisal and/or certificate.测量石头被安装后，并验证它匹配的评估和/或证书。 - Carat - How big is the diamond? 克拉 -多大的钻石？ Larger diamonds often cost more per carat due to their size.较大的钻石，每克拉的成本往往由于其规模庞大。 There are 100 points to a carat.有100个点，至1克拉。 Hence a 50 point diamond is 1/2 a carat.因此，50点钻石是1 / 2 1克拉。 (There are 5 carats to a gram.) Always get the actual point size of a diamond rather than a fractional weight. （有5克拉至1克。）始终得到分数，而不是重量的钻石的实际点大小。 Sometimes jewelers will try to sell a .90 diamond as a 1 carat diamond.有时，珠宝商将尝试销售为1克拉的钻石.90钻石。 A .90 diamond should be substantially less expensive.阿.90钻石应大幅度便宜。
