Rocks Gemstones

The determining factors of the quality and value of gemstones are clarity, cut, carat weight and color. All four of these factors are determined differently and display themselves in a variety of ways based on lighting. Lighting plays an extremely valuable role when defining the color of any stone. When deciding the final color of a gemstone, mid-morning light is often the most used. It is the whitest form of lighting and has a neutral effect on the color and hue of each individual stone. Most reputable jewelers will provide photos and evidence of the color of each stone through the use of this form of lighting. There are number of ways that light can affect a stone and these should all be considered when investing in a gemstone.

Luminescence is a very influential lighting factor that determines a stone’s color and its quality. Valuable stones have an undeniable ability to somehow display light even in complete darkness. This fluorescence is a very big factor in the price and quality of each individual stone. This should not be confused with phosphorescence which is the ability for the stone to contain light for a few moments after light has been removed from the room. Fluorescence is the capability of the stone to give off light without being given any light to reflect from whatsoever.

Luster within a stone is the term used for a stone’s ability to reflect light both internally and externally. The smoother the surface of a stone is, the more luster it will have and more light reflection it will be able to display.

The ability of a gem to redirect light is classified as refraction. Many gemstone enthusiasts swear by stones that have the ability to change the direction of light and display it in a number of ways. If a gem is dirty or not cut appropriately it will lose most of its refraction ability and damage the value of a stone significantly.

Another important factor in a gemstones ability to be affected by lighting is dispersion. This is classified when a gem can separate light into a number of different colors. When a gemstone can turn neutral light into a rainbow color, it has an excellent dispersion rating and its value will be directly inflated. Usually, games that have a good ability to redirect can also have a high dispersion rating.

Lighting is a very important variable that should be examined and taken into consideration when shopping for or comparing gemstones. A stone can look completely different in a number of lights and you should compare each stone in varying lights in order to determine its true color and value in the most appropriate way. While many stores will only display the stone in the best lighting, you should move it around and change the lighting that the gemstone is under to ensure that you are aware of all the hues and lighting effects that are evident within the stone you are considering investing in.

Some of treatment procedures are centuries old, while others are relatively new. Gemstone are treated in different ways to improve their appearance. Some of these procedures are centuries old, while others are relatively new. Also, by cutting or polishing gemstone could have fabulous colors and nice sparkle. Treatment or enhancement gemstones means any process to make natural gems improved gem’s color, clarity before cutting and polishing. Please understand that TREATMENT AND ENHANCEMENT has nothing to do with man created gems or synthetic gems. Treating and enhancing gemstone is a very common step to improve gems appearance. Some treatment and enhancement improved by nature are permanent and cannot be detected. Treatment and enhancement procedure so closely resembles what happens in nature, that one cannot always tell if they have been treated after mining or before. Microscopic examination will sometimes reveal an inclusion that burst during heating treatment, but lacking that there is no way to tell exact that heat treatment was done before or after mining. There are many techniques of treated or enhanced gems (More knowledge at http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm). Briefly explanations of the important techniques is given below.

Oiling treatment method has been used form more than hundreds years, mostly emerald treated to derive its beautiful green color and clarity. In the same way, other colored stones such as alexandrite and rubies have been treated this way makes less surface inclusions. So we can concluded that colored oils are used on those gemstone to improve their appearances. This treatment reduces fractures and provide better clarity.
Heat treatment is the most common form and famous enhancement. This is so common with corundum, ruby and sapphire, it is recommended that jewelers inform their customers that they are “probably heat treated”. Heating can cause color of a stone to darken, lighten, or even completely changed and can also improve gems clarity and brightness.
Heating of most kinds of gemstones is a standard treatment procedure. Heating knowledge was passed over generations. Heating Methods vary from simply burning method to highly techniques under regulate temperature (More knowledge at http://www.facedgem.com/gemstone-knowledge/gemstone-treatment.htm).
Diffusion is an enhancement method, commonly used on corundum, added iron and titanium during the heating process of the gemstone, sometime called surface diffusion. Diffusion layer created by adding elements. This layer described as colored coating.
Radiation enhancement or irradiation means pounding material with subatomic particles. In some case, irradiation is followed by heating to produce a better or new color for the gem – such as topaz. Today so many irradiation technique applied and has created shades that cannot found in natural topaz. Same way in tourmaline, irradiation can turn dark pink stone into red. For diamonds irradiation and heating can turned them into browns, blues, yellows, pinks and greens.

What are gemstone ?

Gemstones are generally minerals that have been, or may be, fashioned to use for personal adornment.

Do you know that there are thousands of gemstones and in thousands of colour, and these gemstones are used to make a very spectacular jewelry.

You must have got bored with the same old fashioned gold and diamond jewelry.

Now its time to have something new.

I was very fond of diamonds and I purchased lots of them of different cuts and in various patterns of jewelry. But one day I really got bored with all this old fashioned trend which was running from years. So I decided to hunt for something new..!! Something extraordinary, exotic and that looks better than these gold and diamond kinds.

So, I was on my trip to Sri Lanka, where I found these stones and all of them were so attractive that I bought as many as I can and yes for some I have to sell my own gold jewelry as I was short of money.

Then I searched for the jewelers who make jewelry using gemstones. I ordered a few patterns, and when they were finally completed and were in my hands, I realized that I never had such beautiful jewelry in my lifetime. And on wearing them to parties and public places, I was noticed and asked for the jewelry so many times that I really appreciate the work of the jewelers and the stones.

I got so passionate with them that I searched all over the internet about them, their history, their luster, their structure, their colors, how they are formed, where are they found, synthetic gemstones, imitated gemstones, And I collected on my hard drive. And since then I am always influencing my friends to buy one of a kind. And now I wish to share with all of you over the internet who really are interested in gemstones, jewelry, diamond, etc. so I have paid 500$ to a website designer just to post all of the pictures and data I have been collecting on gemstones and jewelry. And now the website has become like an encyclopedia of Gemstones.

So all who are interested please visit my website Discover the world of Gemstones & Diamonds

I hope you will like and appreciate my work and won?t make it a waste.

Thanks for reading, I hope and suggest you to find an online store and order them.
