The Hobby Of Loose Gemstone Collecting


By Lee MacRae


Many people, young and old, say collecting various loose gemstones or loose diamonds is a favorite pastime. Many people have a great love of the various gemstones you can find just about everywhere in the world. This article will look at a number of factors you should understand in starting in this hobby.


At the very beginning you need to learn all you can on the wide variety of stones available. You'll find it very helpful to know the properties of each stone and prevent you from making mistakes. A knowledgeable buyer is a wise one.


Color is a very important part in evaluating a gemstone. The closer the color comes to its pure spectral color the more highly prized it is. Traditional spectral colors include red, orange, yellow, green, blue, and violet. Colors that are darker or paler than a pure spectral color diminish the value of the stone.


How a stone has been cut is the second most important value determination to consider before buying. The precision of the cut will determine how much light the gemstone stone will reflect. It will fully factor highly in the brilliance of the stone and how much someone will pay for it.


The next factor to consider is the clarity of the stone under consideration. This means the gemstones purity or the absence of internal inclusions, particles or spots within the crystal. Needless to say, stones with no flaws will make a gemstone very valuable.


Gemstones are often categorized according to their size because of being more uniform than carat weight. But different gemstones may be of the same size but differ in carat weights and as a result different prices as well. This is due to gemstone difference regarding specific gravity or relative density depending upon the chemical composition and crystalline structure. Normally a one carat brilliant round diamond with standard proportions will be approximately 6.5 mm in diameter. A comparable a brilliant ruby of the same proportions in size will weigh in at 1.55 carats instead.


Taking up the collecting of loose gemstones can be a great hobby. And there is such a variety in gemstones you can collect. You could try collecting Chrysocolla, Tanzanite and other varieties of zoisite or Zeolite (Thomsonite) and then try others. The opportunities are seemingly endless. And if money is tight you can go hunting for raw gemstones. Take the example of the US. In North Carolina you can find Beryl, Aquamarine, Emerald, Almandite Garnet, Rhodolite, and Pyrope Garnet, Diamond, Cyanitecomma

Tips About quality loose diamonds

In general zircon is transparent to translucent. Impurities cause the various
color. Zircons with a cat's eye effect are known but rare. Some crystals contain
radioactive thorium and uranium. Over time, the radioactivity breaks down the
crystal structure so that such stones (usually green) tend to an amorphous
structure, with a lower refractive index and luster than the crystalline type.
These slightly radioactive zircons are very rare in the trade, but highly prized
by collectors and pose no heath threat to its wearer.
