Gem stone ring
The most people all over the world buy gem stone rings at least once in a lifetime. This is wedding time. When buying wedding or engagement gem stone ring you can choose between traveling from market to market wasting your time or to use the services of online stores that have appraisal organization certificates. In America appraiser can obtain such certificates as Graduate Gemologist trainee, American Society of Appraisers membership, National Association of Jewelry Appraisers membership. If your appraiser got one of these or all of them it's ok.
First thing you should know about your future gem stone ring is its size (or size of your finger). To find it out you can go to the nearest jewelry store and measure it, however there are online services and jewelry stores that are able to send these so called ring sizers via mail. This is actually very convenient if you do not want to leave your home in search for jewelry stores. The next thing you should do purchasing a gem stone ring is to decide the type and style of metal in it. Most common are yellow and white gold with the different alloy amount. Alloy hardens the metal and protects it from different scratches. There are a lot more metals that become more and more popular today. For example, the good choice for a ring can be the platinum. This metal is much harder than gold or silver. And it looks very good with diamonds, that's for sure.
Comparing to the common city markets you have much more choice in online stores. There are thousands of gem stone ring styles to choose from in the whole internet. For example you will find the full variety of diamonds only searching online catalogs. By the way - all gem stones are graded according to four main factors- Carat, Cut, Clarity, and Color. Cut is the shape of the gem. There are lots of different shapes, but only round cuts are considered to be ideal (maximum light is reflected back to you, as a result - bringing out maximum brilliance). If proportions are not ideal the diamond or other stone in your gem stone ring may loss its brilliance a bit.
The carat means the size and weight of a gem. I want to say that big gems are very rare and valuable. And that is why large stones have higher per carat cost. Of course it is the matter of personal likes and budget to choose the gem stone sizes taking in consideration that you won't put a big gem into your ring.
The next grade is clarity. The level of gem clarity describes how much flaws or inclusions gem stone has. Clarity levels are - flawless (no imperfections), VVS (very, very slight), VS (very slight), SI (slight) and I (imperfect). The last ones tend to be ugly looking, cloudy or with potential crack.
Color is the last grading criteria that you should take in account choosing the stone for your ring. There are lots of different colors and they are graded according to the alphabet letters from D (colorless) to Z (yellow diamond).
The final consideration for the buyer is the design of the gem stone ring. Just remember one thing - choose a design you love, but keep in mind the practicality of wearing your gem stone ring forever.
