yes
The ring itself will look the same as a 10k white gold ring. The benifits are that the ring will not tarnish as well as the obvious cost benifits.
Lustrium alloy?
yes
Lustrium is a fictional metal featured in the TV show "The West Wing." It is used as a humorous reference to describe presidential honors or awards given to individuals. It does not exist in reality.
It stands for Yellow Lustrium, a Jewlers alloy
The actual value of 'Lustrium' is nearly impossible to determine because it's nickel-chromium (NiCr) alloy. However, since nickel is so common (It's used as cores for coinage and electro-plating), and since chromium is also fairly common (chrome auto parts, etc), I would be inclined to believe that 'Lustrium' cannot be valued on a per gram basis like gold or silver. A value per ton, certainly, but to compare it to silver is silly.
Silver is a Group 11 transition metal, other Group 11 transition metal include Copper, Gold, and Roentgenium. Silver also has the highest conductivity of any metal, Copper has the second highest. Silver also has the highest thermal conductivity, Mercury has the second highest. Based in appearance, Silver is similar to White Lustrium (a metal used mainly to make jewelry) and white gold.
Lustrium
LTM stands for "Layered in 14K Gold." It means the jewelry item is made of a base metal and coated with a layer of 14 karat gold. So, basically, it's like a fancy way of saying "gold-plated," but with a touch of mystery to keep you guessing.
White gold is a gold alloy.
It depends on the Karat weight. 18K white gold is 75% gold and 25% alloy, 14K white gold is 58% gold and 42% alloy, 9K white gold is 32% gold and 68% alloy. White and yellow gold have exactly the same gold content. The only difference is the alloy mixed with the gold. White gold is usually yellow gold mixed with silver, palladium or nickel.
