When jewelry is designated as lead and nickel compliant, it means that it meets regulatory standards for the permissible levels of lead and nickel content. This compliance ensures that the jewelry is safe for prolonged wear and will not cause allergic reactions or other health concerns related to exposure to high levels of these metals.
In the context of jewelry, "beta" typically refers to the metal's composition, indicating that it is a specific type of alloy. Beta alloys are often used in jewelry-making due to their strength, durability, and resistance to tarnishing. They may also contain elements such as titanium or nickel to enhance their properties.
White gold is an alloy made by mixing gold with white metals such as nickel, palladium, or silver. It is popular in jewelry due to its silvery appearance, durability, and ability to complement diamonds and other gemstones.
"5NV" is likely a hallmark or stamp indicating the purity of the metal used in the jewelry piece. In this case, "5NV" might mean the metal is 5 parts nickel and vanadium combined, though it could also represent a specific blend or alloy. It's best to verify with a jeweler or do further research to confirm the exact meaning in relation to the jewelry.
im not quite sure what you mean but if you mean like the abbreviation eg: Oxygen=O Nickel=Ni
"925" on white gold indicates that the piece is made of sterling silver, which is an alloy consisting of 92.5% silver and 7.5% of other metals such as copper or nickel. It is a common standard used in jewelry to denote the purity of the metal.
Basically it means that the item complies with law regarding its composition. California seems to be the only state forcing lead compliant and nickel compliant laws, setting limits on how much of these elements can be present in order to be safe.
Nickel plated
Nickel Free 925 silver. Namely, sterling silver which is free of nickel traces.
It means the jewelry you hold has a 32.5% of pure silver content. The rest would be an alloy of other metals such as nickel.
Made without Lead solder.
ifi compliant
NR stamped on the back of jewelry means it is a Vintage Avon piece by Nina Ricci. The NR on Avon jewelry has absolutely nothing to do with Nina Ricci. NR is an internal Avon code representing the factory where it was made.
14KW means nickel is used in the gold. It is a less expensive way to make gold jewelry. The downside is nickel will corrode over time and that some people are allergic to it.
The RoHS definition is to restrict certain dangerous substances in electronics. It also restricts dangerous substances in electronic equipment. It restricts lead, cadmium, and other toxins.
NC 925 when used in reference to jewelry would signify that the base materials used are nickel and cobalt. The 925 would mean that is plated with 92.5 percent sterling silver.
In the context of jewelry, "beta" typically refers to the metal's composition, indicating that it is a specific type of alloy. Beta alloys are often used in jewelry-making due to their strength, durability, and resistance to tarnishing. They may also contain elements such as titanium or nickel to enhance their properties.
Compliant means that a person is following a certain set of rules. A person that is compliant is following orders to the letter.
