Wedding Links 婚禮鏈接 4C's of Diamond Quality 第4C的鑽石品質
Diamonds are graded by four characteristics: cut, carat (weight), clarity, and color.鑽石分級的四個特點：剪切，克拉（重量），清晰度和色彩。 All four of these properties determine how much a diamond is worth.所有四個這些屬性確定多少鑽石的價值。- Cut - What is the proportion of the diamond? 切 -什麼是鑽石比例？ Round brilliant diamonds are commonly cut with 58 facets.圓形切割鑽石通常以58面。 The better proportioned these facets are on the diamond, the more light will be reflected back to the viewer's eye.較好的比例，這些方面是在鑽石，將更多的光線反射回觀眾的眼睛。 This is extremely important. When cut properly, the diamond will sparkle more.這是非常重要的。切好後，鑽石會綻放。 Diamond cuts are measured by the table percentage, so always ask for it.鑽石削減測量表的百分比，所以總是提出要求。 A good table percentage is between 55-60%.一個好的表比例55-60％之間。 Cut also refers to the shape such as: round, pear, and oval.切還提到了形狀，如：圓形，梨形，橢圓形的。
If you are having a diamond mounted, write down the measurements of your stone.如果您有鑽石的安裝，寫下你的石頭測量。 Measurements never change.測量不會改變。 Measure the stone after it is mounted and verify that it matches the appraisal and/or certificate.測量石頭被安裝後，並驗證它匹配的評估和/或證書。 - Carat - How big is the diamond? 克拉 -多大的鑽石？ Larger diamonds often cost more per carat due to their size.通常較大的鑽石，每克拉的成本更由於它們的大小。 There are 100 points to a carat.有100個點，至1克拉。 Hence a 50 point diamond is 1/2 a carat.因此，50點鑽石是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。）始終得到實際點大小的鑽石，而不是一個小數的重量。 Sometimes jewelers will try to sell a .90 diamond as a 1 carat diamond.有時，珠寶商將嘗試銷售0.90鑽石為1克拉的鑽石。 A .90 diamond should be substantially less expensive.阿.90鑽石應大幅度便宜。

I1, I2, I3 : have inclusions visible to the naked eye 為I1，I2，對應原館內I3：有內含物可見肉眼 - Color : Diamond colors generally range from D - X for white and yellow diamonds. 顏色 ：鑽石顏色從D一般範圍- X的白色和黃色的鑽石。 D is the whitest. D是白的。 Around S they become "Fancy" yellow Diamonds.大約擰他們成為“花式”黃色鑽石。 One can also find green, pink, red, blue and brown diamonds - though these are usually irradiated.還可以找到一個綠色，粉色，紅色，藍色和棕色鑽石-儘管這些通常照射。
Be certain to ask: Do you guarantee the color and clarity of your stones?肯定要問：你保證色彩和清晰度你的石頭？ Many states allow dealers to be off by one color and/or one clarity.許多州允許人要過一個顏色和/或一個清晰。
