Methods To Figure Out A Real Diamond From A Phony

Getting a professional to test the diamond is the simplest solution to the problem of determining whether a diamond is real or fake. With new better fake diamonds available, it is more and more difficult to identify a real diamond even for a professional with a jewelers’ loupes.
There are some regulations of the thumbs.. If you are thinking of buying a diamond already in a setting, examine the setting and look for a metal stamp inside the band that will show the grade of gold, i.e., 10k, 14k, 18k, or Pl (platinum), as if you see these markings indicating a quality setting, it increases the odds that the stone mounted in it is real.
If you have a powerful magnifying glass or a jeweler’s loupe, examine the girdle-band and edges of the cut stone. If the edges are soft and rolled, it is an indication of a fake one. So does a clear, waxy-even strap where the facets get together and alter direction around the “belly” of the stone.
Use a jeweler’s loupe to check the stone for minute fractures, little flecks, and inclusions. It’s hard to replicate these features, which are naturally occurring and very elaborate at the microscopic level. Minor flaws that are all to commonly allowed through cannot be easily spotted by an amateur, and natural diamonds are most valued when they are least flawed.
A common indicator is weight. Substitutions for real diamonds use many materials that are heavier or lighter and the most common substitute, cubic zirconium, is actually a bit heavier than the real gem. You need a precision scale and few genuine diamonds to be able to compare them.
It is a bad idea to use your diamond to cut glass. When checking jewelry for content do not use acid tests primarily used on metals. Don’t give in to your curiosity and try to smash a diamond because it will crush because it is a crystalline material. Just fog the stone. A pure diamond shifts the heat very fast to clear the stone before you can see it. Its only a hint, nothing else and its not definite. Composition stones, that have a base of one material and a table of diamond, will pass the test and at the same time compare the valueless in terms of true worth.
When you want to know for sure if the diamond is truly real, you must have someone reputable give it his opinion of it. That is why extra caution should be used when choosing a new jeweler, and each new gem or stone should have come with a certificate of authenticity. (stones are individual and documentation goes a long way in establishing its nature). To get a correct and fair appraisal, a professional jeweler, can be a reliable and helpful source, as long as he has good sources for his information.
Think very carefully before going to a chain jeweler for an appraisal, which is not meant as an insult to them. Mass produced manufacture of broad distribution shows both strength and weakness. Chain jewelry stores while competent in themselves still will not give you the expertise of a higher end store or assessment business.
After you’ve found an appraisal service by searching online or in the yellow pages, make sure you thoroughly vet the assessor by looking at his or her experience, licensing and background. The best indicators of a skilled jeweler, is someone who is licensed, a journeyman from a traditional trade program, or someone who used to be a stone dealer.
Request that you be allowed to observe the testing of any stone you bring in. This is to escape swapping from dishonest jewelers.. If you are turned down, turn around and just walk out. You can ask for complete documentation if you intend to buy a stone.. Identifying real diamonds is difficult enough to make even pros think twice and look three times.
