Gold is one of the precious metals that is used in our day to day life in the form of gold jewelry like white gold chains and initial pendants. Among the various factors that are considered in buying gold jewelry it is important that you consider the karat of gold in the gold jewelry that you buy, whether it is white gold chains or initial pendants or any other gold jewelry. Pure gold is 24 karat which is not good for making jewelry. Some other base metals are mixed with pure gold so that its physical properties are altered to make gold jewelry. The number of parts of base metal that is mixed with pure gold is important in the quality of the gold jewelry that is made.

If you are buying 14 karat white gold chains, you should know that gold in that jewelry is 14 parts and the remaining 10 parts is some base metal. The higher the karat of gold in the gold jewelry the higher is the composition of pure gold in that jewelry. The choice of the base metal used in gold gives the yellow color or the white color for the gold jewelry whether it is initial pendants or white gold chains.

Last week I bought some DVD media. I generally tend to buy stuffs at their face value & don`t read the fine print written over it too often. However, yesterday a friend came over to my place & told me that i should have gone for the lightscribe CD instead of the kind of DVD & CD media that I had bought. I was like what the heck…what’s, a lightscribe CD anyways! Then he told me it’s nothing too technical. In fact all that a lightscribe CD or DVD would help you with is to allow you to create direct-to-disc labels, instead of the stick-on labels which the normal one supports & unfortunately I bought those normal ones. After a few minutes debate with my friend I became convinced that lightscibe CD or DVD is the ones that I need to buy…from now on at least. However, there`s one thing that would be necessary & that`s the fact that my DVD media writer should be able to handle a lightscribe CD. If it cannot process a lightscribe CD & fails to create direct-to-disc labels over it then, it defeats the whole purpose of buying them in the first place.
