VS 1 Very Fine Quality. Small pin-pricks are just visible to the scrutiny of the close naked eye. However, the beauty of the gem is not diminished in anyway.
VS 2 Fine Quality. Small pin-pricks and feathers are just visible to the scrutiny of the close naked eye. However, the overall beauty of the gem is still not diminished.
SI 1 Good Quality. These gems have inclusions which are fairly easy to see to the close naked eye. However, the overall beauty of the gem is still high.

Diamond Grading


Many experts name color as the number one consideration in choosing a diamond. A diamond's color is graded on an alphabetical scale from D-Z, with D being absolutely colorless and Z being light yellow. Beyond "Z", a diamond is considered to be an exotic or "Fancy" color.


























Near Colorless

Faint Yellow

Very Light Yellow

Light Yellow

Since color differences can be so subtle, they are impossible to determine by the untrained eye. To grade a diamond, gemologists often place it on a white background next to another diamond that has been previously graded.

If all other factors are equal, the less color in a diamond or the higher color rating, the more valuable a diamond becomes. Likewise, as the amount of color increases, the price of a diamond decreases (though this does not necessarily reduce the beauty of a diamond.) 


All diamonds have identifying characteristics, but most are invisible to the naked eye. To view a diamond, experts use a 10x magnifying loupe which allows them to see the appearance of tiny crystals, feathers or clouds. These natural phenomena are called inclusions.There are five categories in class that anyone interested in purchasing a diamond should be aware of when grading clarity.













Internally Flawless

Very Very Slightly 

Very Slightly 

Slightly Imperfect


 FL (Flawless) - IF (Internally Flawless)
Flawless Diamonds reveal no flaws on the surface or internally are the rarest and most beautiful gems.

Internally Flawless Diamonds reveal no inclusions and only insignificant blemishes on the surface under 10x magnification.

VVS1 - VVS2 (Very, Very Slightly Included)
Very difficult to see inclusions under 10x magnification. These are excellent quality diamonds.

VS1 - VS2 (Very Slightly Included)
Only looking through a 10X loupe can pinpoint the inclusions in this category and are nearly impossible to see with the naked eye. These are less expensive than the VVS1 or VVS2 grades.

SI1 - SI3 (Slightly Included)
Diamonds with inclusions easily identified under 10x magnification. Finding flaws in this category with the naked eye is difficult. The gems in this category maintain their integrity, depending on the location of the inclusions.

I1 - I3 (Included)
Diamonds with inclusions which may or may not be easily seen by the naked eye. The flaws on the stones in this category will have some effect on the brilliance of your diamond.

 Carat weight

One carat is the equivalent of 200 milligrams. One carat can be divided into 100 "points". A .75 carat diamond is the same as 75 points or a 3/4 carat diamond. Since larger diamonds are rarer than smaller diamonds, the value rises exponentially with carat weight.

Cut & Shape 

A diamond's cut will most certainly influence its fire (the lovely rainbow colors that flash from within) and brilliance (the liveliness and sparkle), as well as its perceived size and even, to some degree its apparent color. Different cuts reflect light in different angles. A diamond must be cut in a geometrically precise manner to maximize its brilliance.

Diamond & Gemstone Treatments

Nearly all of the genuine Jewelry Quality Colored Gemstone and Fancy Color diamonds available on the market today have undergone some form of treatment or enhancement, either in rough or finished stages of production,  including heating, oiling, irradiation, lasering, heat and pressure etc. and are all done prior to our importing or purchasing  the stones. Each country uses different methods, many are protected trade secrets, and we do not know all of the methods used. If required we can send the gemstones or parcels  for independent evaluation or certification. All purchases come with our 100% return guarantee.  Certified,  Natural, untreated gemstones are available in the higher quality grades.  Nenoir Diamonds, Certified Canadamark White Diamonds, Jeweltree Foundation Certified Diamond Parcels, Garnets, and the Emerald and Australian Sapphires we have made at our custom cutters in Thailand are guaranteed natural and untreated.

Gem treatments have been around for decades. Some treatments are so commonplace that certain stones almost always receive them. Such treatments improve the appearance of the gem and do not negatively affect the stone in any way. They are considered the normal way of handling that particular gem. Other treatments are more limited and may not be stable. All traditional treatments, their purposes, and their effects, are listed in The Gemstone Enhancement Manual, a de facto standard endorsed by major jewelers' organizations.
