I bought a (gold?) ring from someone in the street for £10, and it has the markings '750' and '18k' on the inside. Now I know its not english gold as it doesnt have any english hallmarks on it. But it looks like gold and feels like gold. How can I tell for sure? Besides taking it to a jeweller.

Real gold Jewelry will have a marking on it somwhere telling you exactly how many KTs are in the jewelry if it is real. If you don't find any Kt markings then it is fake or gold plated!! Gold Know your karats* Look for the karat mark, which will tell you that the piece is real gold and the percentage of pure gold it contains. Pure gold, or 24K, is rarely used because it is soft and easily damaged. Instead gold is alloyed with other metals, such as copper, silver, nickel and zinc, to give it strength and durability. Different proportions of these alloys also give gold its rose, green, or white coloration. 18K gold is 75% gold; 14K is 58.5%; and 10K is 41.6%. The higher the karatage, the richer the color will be--and the more costly. In the U.S. jewelry must be at least 10K to be legally sold as real gold. (In Canada and Mexico, the minimum legal standard of karatage is 9K and 8K respectively.) Imported gold jewelry may be stamped with different numbers. For example, the European markings for 14 karat gold jewelry is 585; for 18K is 750. Look for the trademark On karat-marked jewelry sold in the U.S., always look for the manufacturer's trademark. By U.S. law it must be there. When there's a hallmark, it means the manufacturer stands behind the accuracy of the karat mark. You may also find the country of origin marked. Evaluating price In addition to karat weight, the price of gold jewelry is determined by several factors: total weight; design and construction; and ornamental detailing, such as engraving or Florentine finish. Although nearly all gold jewelry today is made with the help of special machines, some handwork is always involved. The more there is, the higher the price. The good news is that through modern manufacturing technology, large, lightweight, and exciting pieces can be surprisingly affordable. Check the clasp When buying a gold necklace or bracelet, make sure you examine the clasp to see if it is strong enough to support the chain, especially if the piece does not have a hallmark. Run your hand over the chain and look for any rough edges. A well-made piece of gold jewelry should look and feel like the quality piece it is. And if you take the time to look it over, you will have a piece that with good care can last a lifetime. * Don't be confused with "carats," the weight measure used for diamonds and other gems.

This goes way back to when Archimedes yelled " Eureka." If the density of the gold is less or more than 19 g/cm cubed, then the gold is fake. The density of the gold has to be 19 g/cm cubed, otherwise the gold is fake. Always ask for the density of the gold before you buy it from the jeweller.

Take it to a jeweller!
Probably plated metal and worth a quid if that!
You've probably been conned - UK gold has hallmarks on it - do a google search for gold hallmark/assay office stamps or letters - it will tell you all you need to know!

A very simple test is to bite it. If your teeth mark it then it probably isn't Gold. By far the best way is to get an experienced jeweller to value and grade it, if it is not gold it is likely they can also tell you what metal it is.

Three ways you can check gold are with
Visual tests - based on color and gold purity markings.
Acid tests - based on reactions to nitric and hydrochloric acid.
Price tests - based on the current market price of gold.

"Rolled" gold, as it's called, will turn dull, & the gold will fade, leaving a dull silvery colour. Real gold won't fade at all.
