Significance in terms of astrological purpose: Stones are worn to ward off evil. It protects us against the bad effect of planets, known to boost the spiritual power of our body keeping us happy and healthy. Gems are graded by four qualities, known as the "four C's." These stand for Colour, Clarity, Cut, and Carat, (meaning size.). The first thing a consumer needs to understand is that gemstones are graded by the rarity of their features. Even though we use the term "quality" that does not necessarily mean that one gem is better than another. On the contrary, what is best for you personally may not be the top, or rarest grade of a gem.
When a mineral deposit is found there will be a wide variety of qualities. For example, let's say someone just mined 100 pounds of amethyst. One of the first things the grader will notice is the size variation. The smaller stones will settle to the bottom of the pile and the larger ones will demand the most attention.
A 100-carat stone is much less common than a one-carat stone and that feature will add to its value. However, simply being larger does not mean that it is better. A small woman could not wear a huge stone gracefully. This would not be the best gem for a small person.
For Purpose of astrological gems the most important criteria are as follows:
The stone should be the same carat that has been recommended by the astrologer. Like a doctor’s prescription of medicine a smaller or larger dosage than what has been prescribed can be ineffective and even harmful.
It must be a natural stone. A natural stone comes with impurities and clouds. They are responsible for the right colour of the prescribed gem.
There should not be any cracks. But one must not confuse cracks with impurities and clouds.
Unclear as to whether one should be warned against this or that these gems are better than other gems?
The ring must be manufactured as per astrological specification that may not be the most stylish design. The astrological specification ensures proper transmission of light through the gemstone into our body.
The ring must be worn on the finger that has been specified by your astrologer.

Colour
Colours are described by three factors:
Hue, (red, green, blue, etc.)
Saturation, (strong or pastel, red or pink.)
Tone, (light to dark.)
Generally speaking, highest values go to stones with pure hues and strong rich colours. With high value gems, subtle variations make a significant difference in price. For example, a slightly organic ruby will not be worth nearly as much as one that is pure red. Most people cannot see the difference, but to the expert grader it is significant. On moderate priced gems, colour has less affect on value. For example, tourmaline comes in every possible color. Unless it is an exceptionally pure green, red or pink, they are all about the same value. It is the other factors of size; clarity and cutting that determine the gem's value.
Diamonds are graded on how close they are to being colourless. There are three grades of "colourless" that only vary by subtle differences in transparency. Then there are four grades of "white." These are gems that will appear colourless when set in jewelry. It takes an expert in a laboratory setting to distinguish between these grades, but each represents a change in value.
Clarity
Gemstones contain a wide variety of "inclusions." In a faceted gem, an inclusion is defined as anything that will interfere with the free passage of light. They can be little bits of minerals, hollow areas, or fractures.
As with color, tiny differences, which are only apparent to the grader, have a significant affect on value. The best examples of this are diamonds. There are several grades where the inclusions are invisible to the naked eye and have no affect on the beauty of the stone. Yet the difference in value, between something that is very difficult for an expert to find with 10-power magnification and something that is easy to find with magnification, is substantial.
Most colored stones are simply graded "eye clean," (meaning that the inclusions are not visible to the naked eye,) slightly, moderately, or heavily included. Gems with eye visible inclusions are always lower in value, but the change is not applied equally. There are three classes of colored stones, those that are "usually clean," those that are "usually included," and those that are "almost always included." Emeralds fall into the last category. Their clarity cannot be compared with other gems. If you want an emerald without any eye visible inclusions, you are limited to small stones. If you want a larger emerald, you will have to accept a certain amount of inclusions and find its value in the color. Fractures and cracks are not allowed in astrological gems.
Cut
The cut of a gemstone, the workmanship that went into fashioning it, is one of the most important factors in its appearance. It is also one of the most difficult factors for the non-professional to judge because of the number of variations involved.
The first thing to do is to look at the shape of the stone. Some gems are cut "freeform" but most are intended to be a regular shape. If so, look at the symmetry. Does it bulge here or there, or is it symmetrical in all directions. Look at the stone from the side and the ends. Again, it should be symmetrical in all directions. If not, it is up to you to determine how much it will affect your appreciation of the stone.
When considering a gem, insist on inspecting it with magnification. Look at areas where light is being reflected from the surface. They should be smooth and mirror like. If you see pitting, scratches, or dull areas, the gem is not well polished. It may look good in the store, but someday you will compare it with a well-polished gem and be disappointed with your purchase. If it is a faceted gem, look at the facets junctions also. On a well-cut stone, they will be crisp and come together in a single point. You may see facets that are slightly rounded and not quite meeting where they should. Just how far off they are will affect the brilliance of the gem.
The other factors in a faceted gem are too complex for the layperson. However, you can get a good idea of the cutting quality simply by comparing it with other gems. When you do this, make sure you are comparing similar stones. An amethyst will never have the brilliance of a topaz and dark stones will not be as bright as light colored ones. When comparing like stones, what you want to look for is the overall light return, the brilliance and sparkle of the gem. It is entirely possible to look at two gems with the same size and coloring, but one having much more brilliance and sparkle than the other. This is the result of cutting.
One thing to pay special attention to is "windowing." That is where light passes straight through the center, rather than being reflected back. It is easy to spot; the center will be much lighter than the outside of the gem and have no flashes of light. Some windows are small; others are quite large and hideous. This is another example of something that might look good in the store, but someday you will compare it with a well-cut gem and be disappointed with your purchase.
Cabochons are easier to judge.we should begin by checking the polish under magnification. Then hold the stone a short distance from your head and rotate it slowly. Notice how the light passes across the surface. On a well-cut gem, it will flow smoothly from one side to the other. If it is poorly shaped the light will not flow smoothly, but snake across the surface. Surface irregularities and poorly polished areas will also show up this way.
Carat
Simply put, larger stones are less common than small ones. Hence, they demand a higher price per carat. For example, a quarter-carat topaz may cost $60 per carat, or $15. A half-carat topaz, (with the same color, clarity and cutting grades,) might cost $100 per carat, or $50. A full carat topaz would cost $200.
Choosing the right size is a personal matter. For the bold, dynamic individual, a large gem mirrors their personality. On the other hand, small stones are better suited to someone with delicate and feminine tastes. Most people will fall in between these two extremes.
Then budget is a strong factor, smaller stones have a significant advantage. Not only do they cost less per weight, the amount of gem you see is disproportionate to their size. The reason is that volume goes up faster than the outside dimensions. For example, a half carat, round diamond measures 5 mm in diameter, a ¾ carat diamond 6 mm, and a full carat 6.5 mm. From a casual observation, the half and ¾ carat stones, or the ¾ and full carat stones look to be about the same size, but the price difference can be considerable.
Small gems are often clustered to give the illusion of more gemstone. Seven 1.6 mm diamonds, set close together, will take up as much space as a whole carat diamond. If set on white gold, it is hard to distinguish the separate stones, hence these are often called "illusion settings". For astrological purpose a single diamond is necessary and not cluster of small diamonds making up the weight.
While these seven stones approach the eye appeal of a one-carat diamond. They only weigh .14 carats. Considering that the price per carat is also much lower, the cost difference is significant. A cluster ring would be in the hundreds of dollars, rather than the thousands.
Conclusion
This guide is intended to help you understand the factors that go into grading gemstones. You have learned that the term "quality" has to do with the rarity of a feature, not that it is necessarily better than something else. The beauty and uniqueness of a gemstone lies in its natural imperfections. These are in fact what make them Perfect!
Gemstones are not only beautiful, but also very valuable, there are innumerable synthetics and imitations. So how can we protect our self from these 'fakes'? Well, the best way is to buy from a specialist in whom one has confidence. Large emeralds in particular should only be purchased with a report from a reputable gemological institute. Such an institute will be able, thanks to the most modern examination techniques, to differentiate reliably between natural and synthetic gemstones and will inform us as to whether the stone has undergone any treatment of the kind a purchaser has the right to know about.
We in Nanubhai Gems will ensure that you receive the most astrologically effective gemstone keeping in mind your budgetary considerations.
