Collecting Prescious And Semi-Prescious Stones
By Lee MacRae
Many people, young and old, say collecting semi-precious and precious gemstones like loose diamonds or loose gemstones is a passionate hobby. They simply love the beauty and the colors of the wide array of gemstones found around the world today. Follow along as we discuss a number of things you need to know in starting in this hobby.
To begin with you need to read up on the wide variety of stones available. This knowledge will help you to know what exactly you're looking for so you buy the right items. A knowledgeable buyer is a wise one.
First, color is a major part in evaluating a gemstone. The closer the color of the gemstone is to its purer spectral value the more valuable it is. Traditional spectral colors include violent, blue, green,, orange and red. Colors that tend to be paler or darker than the pure color are considered a lower value.
The cut of the gemstone is an important aspect to consider when buying a gemstone. The cut has to be done in a way that reflects light back to the viewer. A gemstone with the poor cut will not reflect light in a consistent way. Color tone, saturation, and hue will never be consistent.
The clarity of a gemstone is an important consideration. Gemstone clarity relates to the absence of flaws or blemishes inside the stone. Generally speaking, a clearer stone is obviously worth more. To determine the flaws not seen with the unaided eye requires a 10X gemstone loupe or gemstone microscope. Serious hobbyists will use a jewelers diamond gemstone loupe 10X for viewing stamps, coins, beads as well as gems.
You will often find that gemstones are often listed according to their size because it is more uniform than carat weight. But different gemstones may be of the same size but different carat weights and consequently, different in prices as well. This factor comes from the difference of relative density or specific gravity depending upon the materials chemical composition and characteristic crystalline structure. A one carat round brilliant diamond, for example with normal proportions is approximately 6.5 mm around. A comparable a brilliant ruby of the same proportions in size will weigh in at 1.55 carats instead.
Collecting gemstones as a hobby can give you an enjoyable pastime and rewarding in the long run. You can start small and don't have to spend a lot of money and yet you can build a very exquisite collection. Many people love to take vacations to go hunting gemstones. Just in the United States in Colorado you can find Beryl, Aquamarine, Phenacite, Garnet, Amethyst, Agate, Citrine, Pyrite, Rose Quartzcomma
