Starting To Collect Gemstones
By Lee MacRae
Gemology is the science, art and profession of identifying and evaluating rocks known as natural diamonds or loose gemstones. A number of people taken up gemology as a hobby. They become interested in collecting and evaluating loose diamonds or loose gemstones. Some people even begin to visit various locations close by or even in other countries to look for rough gemstones. Some hobbyists will learn to cut or tumble the gemstones they find. If this hobby interest you follow along as we discuss the different aspects of this hobby.
The first thing you need to do in becoming a gemstone collector the proper way is through the power of knowledge. By visiting a local library you can find books on the subject that will let you make wise purchases from the beginning.
The first criteria you need to evaluate is stone color. Gemstones are the most intensely colored natural materials you can find. Gems have become so synonomous with color, they've even become associated with particular ones. Everyone knows ruby red, emerald green, sapphire blue, aquamarine, turquoise, and jade green Gemstones are valued much higher the closer they are to the colors in the spectrum of orange, green, yellow, violet and blue. They drop in value the farther they are from the spectral color.
Gemstone cut is an important aspect to consider when buying a gemstone. The stone has to be cut correctly to reflect light properly. A gemstone with an improper cut will be muted or washed out. Color tone, saturation, and hue will never look consistent.
The clarity in a stone is the next item to consider. Clarity refers to the absence of flaws or blemishes inside the stone. Generally speaking, a clearer stone is more valuable. To determine the flaws not seen with the unaided eye you need a gemstone loupe (gemstone clarity magnifier) or gem microscope. Serious hobbyists will use a 10X jewelers were gemstone loup for viewing their coins, beads, stamps or in our case gemstones.
Gemstones are often categorized according to their size criteria since it is more uniform than carat weight. But different gemstones may have the same size but have different carat weights that result in different pricing structures. This factor comes from the difference regarding specific gravity depending upon the chemical composition and crystal structure type A one carat round brilliant diamond, for example 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.
Although gems are frequently used in jewelry, they are perfectly good collectibles in their own right. In fact, there are many attractive and interesting gemstones that are too fragile or too large to be used in jewelry. Take each gemstone and consider it as a piece of art and value it for its unique nature and vibrant colors. And unlike many hobbies where you have to buy everthing you can actually go hunting for raw gemstones in the field. In the US in Idaho you'll find Garnet, Opal, Agate, Obsidian and Sapphire. And in Canada you can hunt for nephrite jade in Cry Lake, British Columbia or blue spinel from Daillebout, Quebec along with amethyst from Nova Scotia. Think of gemstone collecting for the great hobby it is.
