why does gold turn my fingers green?

It's actually the substance that's mixed with the gold that's probably causing it. It's something to to do with alkelines and acids or something. Gold is mixed with all kinds of stuff to make jewellry because in it's pure form it't too soft to do anything with. \n\nSo your probably allergic to the metal that's in it (usually Zinc).

Gold is seldom found in its raw form, usually it's an ore, together with other metals etc. After mining this ore, it needs to be processed, usually it is ground to small bits and then treated chemically, but there are other ways, too.\n\nAt the end of the day, you have gold in the form we know and value. Even so, since gold is such a soft metal, it is usually sold in alloy form, with silver, copper, platin, palladium or other metals. This also gives it its color, which can range from red, to silver-white, golden, green or even blue.

Ask a jewler I guess, they can turn gold into white gold

Could this be a sign of scurvy, lack of vitamin c or do you use bleach too often.  Try using gloves to do chores and moisturize your hand with cocoa butter at nights.

Here is a detailed list of what causes bronze to turn green:  (It's corrosion)\n\nhttp://w3.gsa.gov/web/p/hptp.nsf/035c614b995c0406852565d1006211b3/6c8c800d5618e023852565c50054b2c6?OpenDocument\n\nFrom the article:\n" THE CONVERSION OF THE TOPMOST METALLIC SURFACE TO COPPER\n     SULFATE normally begins to occur on surfaces with the most\n     severe exposure, such as horizontal surfaces.  Oxygen\n     deprivation and deposition of particulates and moisture create\n     a  catalytic situation where electrolytic reactions occur.\n     (This is the same principle as a battery, where the charged\n     ions move from a positive to a negative pole.)  The visual\n     symptom of this phase is the formation of thin, light green\n     patches on the more exposed areas."\n\nIt also discusses Suphurization, which can also result in a green color. \n\nCheers!

There are several vertebrates with blood that is green in color as a result of a buildup of the breakdown products of hemoglobin. This is a natural state for these species.

You can change your yellow gold ring to white by having a jeweller coat it with rodium.  This is not permanent, it will eventually wear off.

"White gold is an alloy of gold and some white metals such as silver and palladium. White gold can be 18ct, 14ct, 9ct or any karat. For example, 18ct yellow gold is made by mixing 75% gold (750 parts per thousand) with 25% (250 parts per thousand) other metals such as copper and zinc. 18ct white gold is made by mixing 75% gold with 25% other metals such as silver and palladium. So the amount of gold is the same but the alloy is different.\n\nTraditionally nickel was used in white gold, however, nickel is no longer used in most white gold made today as nickel can cause reactions with some people. We do not use nickel in our white gold\n\nWhen white gold rings are new they are coated with another white metal called Rhodium. Rhodium is a metal very similar to platinum and Rhodium shares many of the properties of platinum including its white color.\n\nThe rhodium plating is used to make the white gold look more white. The natural color of white gold is actually a light grey color. The Rhodium is very white and very hard, but it does wear away eventually. To keep a white gold ring looking its best it should be re-rhodium plated approximately each 12 to 18 months. Most local jewelers are able to rhodium plate jewelry for a cost effective price."

then perhaps it is something to do with the base photo that you are auto-levelling in that it has a lot of green hue in it?\n\nremember, auto levels adjusts contrast/brightness more than colour balance so it's just revealing what was already there. \n\nif you want to tone down green in the photo, you need to adjust the colour balance and reduce the green slider.

definitely green. my guitar's color is green. It's name is Kara. lol

pllatinum is not white gold. The pure element Au is not white gold. \n\nWhite gold is an alloy of gold mixed with white metals such as nickel, silver, and palladium. Like yellow gold, white gold glitters in a variety of carats: 18ct, 14ct, or 9ct. \n\nEighteen-carat white gold consists of 75% gold mixed with 25% white metals. New white gold rings are usually coated with a hard protective finish of rhodium, a silver-white metal like platinum. To keep a white gold ring looking its best, Gillett's recommends an annual replating of rhodium, since the coating wears off over time. \n\nPlatinum, an entirely different element than gold, is a white metal that is denser, heavier, and longer-wearing than gold. It's usually used in almost pure form and does not require a protective coating. Platinum is quite expensive, a platinum ring is perhaps twice the price of a similar ring made in white gold.

It's actually a bluish-green.  Look at your veins that come to the surface of your skin.  Blood only turns red when it comes into contact with oxygen.

Basically as everyone suggests it is to do with magnetism. when electrical items are operated they generate electrical fields that in turn have magnetic fields. the same can be said for fixed magnets. These fields bend the "beams" within the CRT and illuminate the wrong phosphors. such a phenomenon Displays as a purple pink (usually) or red patch on the screen. The degauss coil you operate when you push the button generates a small localized magnetic field of its own which slowly dissipates as electrons through the components within the circuit thus restoring the CRT's normal magnetic field, resulting in the proper phosphors within the CRT being excited rectifying colour problems on the display

I stand corrected, as usual.  The people below are correct in that the wavelength of the light is not correct for you to see your finger bones.  It takes a certain wavelength (e.g. X-rays), not the light that's coming from your mouse.  You probably also need the proper "background" to see it correctly.

The gold reclamation process from computer parts (primarily cpus and connecting pins) involves the use of dangerously strong acids and should only be attempted by someone who has researched the process carefully. The 2 items which contain the most gold use similar processes with slightly different acids. I have tried this approach and found more effort in the process, required chemicals, and discarding of the waste products than the value of the gold I recovered.\nThere are a few sellers on EBay and other sites who will gladly sell you the information you need but rest assured that there is more money selling the process to individuals than thay make recovering.\nMay I suggest you sell your CPUs and "finger connectors" on EBay, (just use sheetmetal snips to cut the connector section from the board) they will fetch you a good price with a LOT less effort.

you could put it in water and see if it tarnishes quickly?\n\ngold is relatively stable, and doesn't tarnish. you could also try to test it's electrical conductivity if you have an ohm-meter. gold conducts electricity very well. you may need more info to do this though.\n\ngood luck
