- Medium Dark
The Gemstones with Color Tone Medium Light to Medium Dark are Most Valuable ones.

And they have their own importance in defining for the color of the Gemstone. The Higher the Intensity of the Color the Higher will be the Value of the Gemstone.

50 to 70% weightage of the Value of Gemstone is classified by Color.
The Existence or the Non-Existence of the Flaws inside (or on the Surface) the Gemstone determines the Clarity as a whole.
The Value & Quality in turn is defined by the Clarity of the Gemstone.
Gemstone with Flawlessness is totally rare on the earth and thereby the price is accordingly placed higher on that.
There will be Inclusions or Tiny Mineral Flaws inside every Gemstone in general.
It is only seen to the Expert Eye or under Magnification. However, sometimes these inclusions don’t affect the Durability of Gemstones. In that case the Value of Gemstone won’t be affected.
In anyways you need to see the Clarity as the Most Important Factor.
Mostly, we won’t be found Clean Colored Stones in reality. No Clarity or Variation Grading System is standardized in the date. In anyways there are no two alike gemstones in this world.
Look for the Inclusion after seeing it by face up on the Table.
If no Inclusions are visible, the Value is higher.
Gemstones (like Emeralds, Sapphires & Rubies) do contain some sort of flaws.
However, those inclusions are pretty invisible to the naked eye.
On the Clarity Ground, Gemstones can be found so clean & at the same time they can contain heavy inclusions too.

Important Things for Gemstone Clarity
In order to examine the Colored Gemstone, we need to see it from the Top or Face up Position. While examine in the same way, if you don’t find any sort of Inclusions the Value or the Beauty will be unaffected. Sometimes Gemstone setting hides for the Inclusions, however you don’t need to worry as value isn’t affected in that as well.

Some Sort of Subtle Changes in High Quality Stones can make an huge Difference in Price as well. As in... The value of below does vary at the greater extent

However, the difference is not that apparent usually to the People. Only Experts can detect the Slightest Detail as they do observe the Gemstones on a Daily basis so.
People with Strong Personalities go for the Strong & Bold Colors of Gemstones.
Rest do prefer the Softer & Brighter Stones. The ultimate Decision can be the outcome of the Skin Complexion or the Outfit of the respective person.
See the Gemstones and you’ll find only fewer among them are having completely Deepest & Richest Colors. These Gemstones are highly in demand thereby the price is comparatively much higher for the same.
Gemstones with the Below Color Variations are generally desired more.

Economically viable Gemstones are coming with Muted Colors & Colors between Hues. They are much impressive in terms of appearance.
However, it is totally & absolutely your Personal Preference that determines the Choice of the Gemstone.
The Cut of the Gemstone
The Final Brilliance & Elegance of the Gemstone is given by the Cut.
Without any darkness or Windowing when the Ideal Cut gets all the light in an even pattern, it becomes the Best Cut Gemstone as a whole.
Cut doesn’t affect the Cost.
However, the Elegance & the Beauty of the Gemstone do depend on the Cut. The Gemstones with Colors get for the More & Different Cut Variations compare to the Diamonds.
Cut doesn’t require any Fixed Rule while Cutting.
However, it should be done with the hands of Skilful Cutter as he does have careful considerations of both Proportion & Yield.
In order to lessen the Amount of Inclusions, Gemstones should be cut in even atleast. Optimal Shape in this case is envisioned 1st by the Cutter. Intensity of Color is also considered.
It is apparent if you reduce the Carat Size the Gemstone will become lighter comparatively. If the Size of “Too Dark Stones” is reduced, the Color gets improved. But the Light Color Stones lose the value if the Size is reduced.
However, we would consider Shape & Cut in order to clarify.
The Physical Form or the Contour of the Gemstone is Shape. And the Cut gets you the result of how Well the Shape is been executed.
The Carat Weight of the Gemstone
In order to know how much the Gemstone Weighs for, the Gemstone Industry considers the Metric Unit of Weight, Carat as the Weight Measurer.
- 1 Carat = 1/5 of Gram
- As in 5 Carats = 1 Gram
In terms of Decimal Fractions of the Carat the Point is 0.01 of the Carat (like 1/100th of the Carat).
Stones with Larger Size are having higher price Per Carat.
However, the relationship between Per Carat Prices & Sizes gets differs with respect to the Group of the Gemstone.
It doesn’t get you the Figures of Dimensions.
The Density does vary from Very Light Stones (as in Opal) to Very Heavy Stones (as in Zircon).
The Cost of the Gemstone
The Price of Any Commodity in the date is pretty much based on the ratio of Demand and Supply. Just like that, the Price of Gemstone does also depend on Demand & Supply values.
Finer Gemstones aren’t available easily in relatively greater quantity.
And people do look for the Exclusive Stones. So Demand is comparatively much higher. Deposits are consumed pretty quickly. So Mining comes to an end. On the other hand, sometimes Deposits on the Surface gets exhausted. So mining seems to become Expensive.
Deeper the Mining Process the higher will be its Expensiveness. It is because of considering other costs (in order to recover the Gemstones) as below.
So Deeper the Depth the Higher will be the Price for the Gemstone in the end. In cases like; if Production Price is higher than the Market Price, the Mining itself will be Stopped.
Sometimes Celebrities do create the demand after wearing Gemstones (like Sapphire, Ruby and Emerald) at Events (like Red Carpet). Demand & Fashion are two driving factors in this way.

Treated or Untreated Gemstones; sometimes there is no Value Variations between them especially in Few of Precious & Semi Precious Colored Gemstones. On the contrary, the Treated Gemstones add the Value of the Gemstone. But then again, High Quality Unheated Rubies & Sapphires are pretty rare. Thereby the Market Selling Price of them is much higher.
