Thing to Know Before You Buy Diamonds
At some point of time, you may be interested in buying diamonds. Before you throw your life savings into the stone, please do your homework and know a little bit about the basic 4 c's of diamond before getting that cheque book out.
4C's of Diamond Quality
Diamonds are graded by four characteristics: cut, carat (weight), clarity, and color. All four of these properties determine how much a diamond is worth.
* Cut - What is the proportion of the diamond? Round brilliant diamonds are commonly cut with 58 facets. The better proportioned these facets are on the diamond, the more light will be reflected back to the viewer's eye. This is extremely important. When cut properly, the diamond will sparkle more. Diamond cuts are measured by the table percentage, so always ask for it. A good table percentage is between 55-60%. Cut also refers to the shape such as: round, pear, and oval.
If you are having a diamond mounted, write down the measurements of your stone. Measurements never change. Measure the stone after it is mounted and verify that it matches the appraisal and/or certificate.
* Carat - How big is the diamond? Larger diamonds often cost more per carat due to their size. There are 100 points to a carat. Hence a 50 point diamond is 1/2 a carat. (There are 5 carats to a gram.) Always get the actual point size of a diamond rather than a fractional weight. Sometimes jewelers will try to sell a .90 diamond as a 1 carat diamond. A .90 diamond should be substantially less expensive.
* Clarity - How clear is the stone? Clarity ranges from flawless (perfect) to I (included). Here is a chart:
Flawless: perfect inside and out
Internally Flawless: may have minor blemishes on the outside
VVS1, VVS2: have very very small inclusions. VVS1 inclusions can only be seen through the pavilion. VVS2 inclusions are more visible.
VS1, VS2: have very small inclusions. VS1 inclusions are harder to see than VS2.
SI1, SI2, SI3: have small inclusions
I1, I2, I3: have inclusions visible to the naked eye
* Color: Diamond colors generally range from D - X for white and yellow diamonds. D is the whitest. Around S they become "Fancy" yellow Diamonds. One can also find green, pink, red, blue and brown diamonds - though these are usually irradiated.
Be certain to ask: Do you guarantee the color and clarity of your stones? Many states allow dealers to be off by one color and/or one clarity.
The price per carat does not increase smoothly with increasing size. Instead, there are sharp jumps around milestone carat weights, as demand is much higher for diamonds weighing just more than a milestone than for those weighing just less. As an example, a 0.95 carat diamond may have a significantly lower price per carat than a comparable 1.05 carat diamond, because of differences in demand. All else being equal, the value of a diamond increases exponentially in relation to carat weight, since larger diamonds are both rarer and more desirable for use as gemstones.
Therefore if you are to invest in a diamond try and get one at 1/2 carat or even better 1 carat.
With a GIA certificate that won't be wrong.
Now go ahead and get that stone!
