The lack of an indicator (10k, 14k, 18k, etc.) are not indicative of whether your piece is gold or not. In the United States, against FTC regulations for the jeweler feature a jewel when it accompanied by a manufacturer's brand. So when I started, jewelry and a mark of me, I think Hallmark ornaments. Now that I have a brand that I bump my jewelry suitable metal punch and my brand manufacturer.
A jeweler can not just look at a piece and say with certainty whether the gold, the jeweler you are trying to find out.
To be precise scientfically a sample of the metal in question is analyzed in a laboratory test will be, but the following two tests are used for many years and are often accurate enough for a craftsman or the owner of the metal in question.
To the question "Is it gold?"
With a small file, make a scratch in a quiet place. While the use of rubber gloves, wood, glass or plastic stick to a reduction or applicationf nitric shown up to the point. Note the reaction. Once done, rinse with water.
If no response is gold.
If there is a bright green reaction, the base metal.
If there is no green zero, which is a layer of gold on the metal (gold-plate, or - if the gold layer is thick enough - goldfilled).
If there is a milky reaction in the ground, which means a layer of gold to silver.
To answer "What Karat Is It?"
Karat identification requires a test kit, with nitric acid, aqua regia, samples of known karat, and a touchstone of slate or ceramic.
The purpose of the tested gold is rubbed on the stone touches ( "") to leave a trail. A parallel line is made with one of the known specimens of carats. Both brands are flooded with acid and observed the reaction. When the sample colors in the same proportion as the test run was a match. Nitric acid is used for low karat gold is aqua regia more carats required.
Note: These testss are for your information. They are not precise enough to trust that a piece is for sale. Most jewelers have testing kits in the decision whether to use some gold, and its approximate karat. It is probably easier to bring the issue to a jeweler in the production of test kits themselves.
inform you about the room. Gold will be reviewed and, if they printed some (is) probably the gild eg closure.
