The colors of diamonds:The color grading of a Diamond is one of few elements that affects its price.
The Color Grading scale of
Diamonds starts from D to Z (D E F G .... etc) and is used to identify the amount of color in each diamond.
(The letters A, B & C are not in use at the color grading scale).
The exact color is determined by a professional gemologist such as our gemologists at Rothem Collection that have years of color grading experience, day by day.
The most colorless color grading is determined by the "D" letter,
while the most colorful grading is determined by the "Z" letter.
At the basics, "D" color which is the most colorless grading,
gives the diamond the most high value, while "Z" grading gives the diamond the most lowest value, but not always:
Sometimes "Fancy" color diamonds which are very rare like fancy yellow, Fancy blue etc.. are more expensive than the D color since their color is so intense what gives them an extremely high price such as the "D" color and even more.
Usually people are looking to buy diamonds graded between G color to J color.
G, H, I & J colors, are considerable as White color which is nearly colorless
that still looks very white to the naked eye, and their price is significantly
much lower than the most colorless "D" color.
For a certain budget, as low as you go further on the color grading scale
(towards Z), The diamond's value goes down so you can afford yourself a better clarity or a bigger carat weight diamond and vice versa.
We, at Rothem Collection, offer you all the color range of Diamonds & Diamonds Jewelry ranging from D to Z. The most popular items you will find at Rothem Collection are ranging from D to K colors which are the most demandable today.
If you have any special desire for a rare color diamond or gemstone which do not appear in our site, you are more than welcome to contact us at sales@rothemcollection.com and we shall gladly fulfill your request.
For our buyers convenience,
we divided the entire colors scale
to five main categories as shown below.
Group1 Colors D, E & F meaning Colorless. (The most expensive)
Group2 Colors G, H, I & J meaning nearly colorless. (The most affordable, popular & demandable)
Group3 Colors K, L, & M meaning faintly tinted, usually yellow. (Less wanted, the price goes lower)
Group4 Colors N, O, P, Q & R meaning lightly tinted, usually yellow. (Even less wanted, very low price)
Group5 Colors S, T, U, V, W, X, Y & Z meaning Tinted, usually dark yellow, may progress to dark brown.
The precise clarity grading is done by a professional gemologist such as our gemologists at Rothem Collection that have years of clarity grading experience, day by day.
In the clarity scale, "IF" describes the cleanest purity and the highest diamond price, while "I3" describes the lowest purity & lowest diamond price.
Here is the complete clarity scale:
This process optically eliminate "feathers", which are naturally occurring in most diamonds.
The result is a more visually stunning diamond that you can purchase for significantly less than a similar-looking, non-enhanced diamond.
An Enhanced Diamond is totally natural and comes from the same diamond mines, the same as all the natural Diamonds. The clarity enhancement process is not visible to the naked eye, and only a gemologist will be able to notice it.
How it is done?
In the clarity enhancement process, microscopic amount of material is inserted into the feather of the diamond. This material has the same optical properties as the diamond. When light goes through a diamond, it either changes its course or reflects in a different direction. When the light attempts to pass through a non-enhanced diamond that has a feather, the light hits the feather and may reflect in many directions. That is why we see the feather, and the diamond doesn't appear to be clean.
After the enhancing process, the light passes through the natural feather because the material used for the enhancement has the same optical parameters as the diamond. The beam of light "thinks" it's still traveling through the same material (diamond) and continues its original course. The amount of material used to fill the feather is microscopic & adds zero weight to a diamond.
