Micrometer is a measuring standard instituted by SI (International System of Units). 1 micrometer= 0.000001 meter = 0.001 millimeter.
Electroplating is a process where electric methods are used to create coalitions between metals by chemical reactions, resulting in durable and qualitative coatings.
Carat and karat
Carat and karat are measurements used in the world of jewelry and even though pronounced the same they drastically differ. Carat is the measurement of the weight of diamonds, other precious stones and pearls and karat is the measurement of the purity of gold.
Carat is based on the common metric system. One carat is one-fifth of a gram, meaning if a diamond is a 5 carat diamond, it weighs 1 gm. A carat is also divided into 100 points. If a diamond is half a carat, then it is called a 50 pointer. As for karat the purity of gold is scaled from 1-24 where twenty-four indicate the purest form. Gold is a soft metal and to make it suitable for jewelry alloys such as nickel, zinc or copper has to be added. How much of other metals that are mixed into the gold effects the karat, for example twelve karate means 50 per cent gold and 50 per cent alloy. Any gold with less than 10 karats is not to be classified as gold.
Gold Vermeil is a classification of a certain standard of gold coating achieved by using the method of electroplating onto sterling silver. What differs vermeil from a regular pleating is the thickness of the gold that is to be at least 2.5 micrometers 0.0025 millimeters and contain no less than 10 carat. The gold used by CbyC is either 18K or 14K. Significant for the gold vermeil classification is the underlying metal that has to be sterling silver as opposed to ordinary pleatings that might be copper or brass. Being made up entirely of two precious metals gold vermeil is extremely durable and holds a very high quality, as well as being a safe choice for metal sensitive skin.
Gold-filled means that the piece is composed of a solid layer of gold, constituting at no less than 5% of the total weight. A gold-filling is created by a mechanically bonding of gold onto a base of either sterling silver or other base metal. Gold-filled jewelry have the same appearance as high carat gold ones an will last up to 30 years even with daily wear. even with daily wear, can last 10 to 30 years though the layer of gold will eventually wear off exposing the metal underneath. The layer of gold on gold-filled items is 5 to 10 times thicker than that of a regular gold plating.
