Our Featured Gemstone ArticleStarting The Hobby Of Gemstone Collecting
By Lee MacRae
Why would anyone collect items like
loose gemstones, you ask? Well for one thing they are very beautiful items. And just like
natural diamonds they can become extremely valuable over the years. Many hobbyists love to collect and work with the nearly 150 types of gemstones found today. Read long as we look at the hobby of collecting
loose gemstones.
The first thing you need to do in beginning this hobby the proper way is by getting adequate knowledge about them. By taking a quick trip to the library or local bookstore you can find a number of books to broaden your knowledge and that will help you to know exactly what you should do.
Number one to look at is the color of the gemstone. Gemstones at the top of the ladder have colors that are close to the exact spectral color of red, orange, yellow, green, blue or violet. Muted gemstone colors or are too dark lowers the value per carat.
Cut is one of the all-important 4Cs and is used not only to appraise diamonds but gemstones as well. A precision cut gemstone highlights the natural color of the gemstone, lessen any inclusions and highlight the proportions and symmetry of the stone. One excellent way to determine the excellence in its cut is to check if it is able to reflect light on a consistent level over the stones complete surface. If the stone is cut on the shallow side most of the light will refract out instead of reflecting internally. The gem appears washed out.
A third consideration is the clarity. This means the purity of the gemstone or the absence of internal inclusions, particles or spots within the crystal structure. Without a doubt, zero flaws will make a gemstone very valuable.
You will often find that gemstones are often listed according to size because it is more uniform than carat weight. But different gemstones may have the same size but different carat weights and consequently, different pricing structures. This is due to the nature of gemstone difference regarding specific gravity or relative density depending upon the chemical composition and crystalline structure. A one carat round brilliant diamond, for example with normal proportions is approximately 6.5 mm around. A ruby that is the same size will weigh in at 1.55 carats.
Collecting various gemstones can be very rewarding hobby. And there are so many different types in precious and semi precious stones that you can collect. You can collect gemstones like Olivine (Peridot), Amethyst (cardinal gem) or Tourmaline for instance. The varieties are nearly endless. And if money is tight you can go gemstone hunting and find the raw materials instead of buying them. Just in the United States in California you can find Agate, Benitoite, Californite, Diamond, Citrine, Tourmaline, Abalone Pearl, Kunzite, Chrysopras

Even the hardest gemstone variety can be vulnerable to breakage if it has
inclusions that weaken the crystal structure. Exercise common sense: if you have
a ring set with a softer gem variety or an included stone, take it off before
strenuous activity. Even the hardest gemstones like Diamonds, Rubies and
Sapphires can shatter with a single well-placed blow especially if they have
inclusions, which weaken the crystal structure.

The Gemstones Review
Gemological Article Of The MonthCollecting Loose Gemstones
By Lee MacRae
Why would anyone collect items like
loose gemstones, you ask? Well for one thing they are very beautiful items. And just like
natural diamonds they can become extremely valuable over the years. Many hobbyists love to find, collect and finish the nearly 150 types of gemstones found today. Follow along as we discuss the hobby of
loose gemstone collecting.
The first thing you need to do is to get yourself some reading material. You want to understand as much as possible about the subject of gemstones. The more you know about the hobby of gemstones the less likely you are to make a mistake. You'll know exactly what to look for in a quality stone.
First on your list to factor in should be gemstone color. You want the gemstone to be as close in color as possible to the pure colors of the spectrum. This means orange, red, violet, green, yellow, and blue. The prices for very pale or very dark semiprecious and precious gemstones are less per carat.
The cut of the stone is extremely important and is used not only to appraise diamonds but you're gemstones as well. A good cut showcases the natural color of the gemstone, lessen any inclusions and show off its symmetry and proportions. One way to determine the precision in the cut is to look at how consistently it reflects the light throughout the surface of the stone. If the stone is cut on the shallow side most of this light were refracted away rather than reflecting internally. The gem appears washed out.
Another factor to look at is the clarity. This refers to the stones purity with no internal conclusions, particles or spots within the crystal structure. Obviously, stones with a lack of flaws are hard to find and make your stones very valuable.
Next thing to look at is the duo of weight and size. Due to their nature gemstones vary and specific gravity or density. Size and weight are not necessarily equal from stone to stone. If you have a diamond that weighs 1.00 carats a sapphire of equal size would weigh 1.20 carats. An Emerald of equal size would be approximately 0.95 carats while an Alexandrite stone would be about 1.23 carats.
Though you may find gemstones used a lot in jewelry, they are perfectly good collectibles in their own right. Actually there are many interesting and attractive gems that are just too big or fragile to be used for jewelry. Take each gemstone and think of it as a piece of art, a miniature sculpture to be treasured for its unique nature and vibrant colors. And unlike many hobbies where you have to buy everthing you can use vacation time to actually hunt for raw gemstones in stead of buying. In the United States in Hawaii you can find Peridot and Coral. And in Canada you can hunt for nephrite jade in Dease Lake, British Columbia or sodalite and rose quartz near Bancroft, Ontario along with hessonite garnet in Asbestos, Quebec. Take up a hobby of loose gemstone collecting and enjoy yourself.

The sapphire has traditionally been involved in the area of religious magic, and
it was believed that the owner of the stone could use it to harness psychic
powers. It was, and still is, the choice of high church officials and regents
especially when their rings are mounted. There are several language origins for
the word "sapphire." In Sanskrit it was known as "sauriratna" in honor of the
planet Saturn. Ancient Chaldean references called it "sampir," while the Greeks
had a modern translation, "sappheiros" which denoted the color blue. The Arabic
translation was "safir" and the Latin texts call it "saphirus."
