A great deal of silver jewelry available today is called 925 silver. Have you ever wandered why we, in the jewelry trade, add the number 925 in front of sterling silver? Before you part with your hard-earned money buying jewelry for yourself, or as a gift for someone else, it is worth finding out what exactly 925 silver is. Furthermore, it is important to understand why you must always insist that your silver jewelry is up to the high 925 standard.
Before we look at what 925 silver is, we must first consider the properties of this fascinating metal. Pure silver is extremely malleable and therefore can be easily damaged. It also softens over time, even at room temperature.
Obviously, in this state, silver is useless for jewelry purposes. To avoid the problems of malleability and softening, and thus to increase the life-span of your silver jewelry, other metals are added to the pure silver. The result of this blending process with alloys is a combined silver and alloy substance which is far more resistant to scratching and damaging.
925 sterling silver jewelry is actually a combination of 92.5% silver and usually 7.5% copper. Sometimes the craftsman replaces copper with another material, or even a combination of materials. Over the last decade lower copper prices and an abundance of copper due to improved refining techniques have made it the first choice of many designers and jewelry stylists.
The beneficial properties gained by adding the copper to the pure silver have made the resulting product extremely popular with a host of silver craftsmen. Earrings, rings, bracelets and all other forms of jewelry can be carefully designed with the assurance that each intricate bend and turn will remain firmly in place.
925 silver is therefore a combination of mostly pure silver and a lower percentage of infused alloy metal. The addition of copper, or occasionally a similar copper-like substitute, helps to enhance your silver jewelry and does not in any way detract from its quality.

Origins of Marcasite Jewellery
Marcasite is the name given the mineral iron sulfide, which is mined all over the world. However, most of the gem called marcasite used in jewelry is actually iron pyrite, since genuine marcasite often crumbles into dust and is thus too delicate to be used in jewelry.
The Incas are the first known civilization to have used Marcasite stones in Jewellery with notable Marcasite Jewellery pieces having been found in several Inca’s burial chambers.
However in 12th century Saint Louis IX of France established a law reserving diamonds for the kings and (aristocrats) nobles. These laws were introduced to protect and regulate the social hierarchies and morals of the lower orders through restrictions on luxury goods ie Jewellery.
Although pyrite (marcasite) has been used in jewellery for centuries, it became popular as a substitute for diamonds in the 18th century, particularly in Switzerland, where the use of diamonds was restricted by law.
Marcasite Jewellery gained its popularity during Queen Victoria's reign after the death of her husband Prince Albert in 1861. After Albert’s death, Queen Victoria only wore dark clothing and Jewellery to symbolize her widowhood and everyone followed her style. The Queen’s favorite Jewellery were Marcasite brooches, lockets, cameos and earrings...
The marcasite used in jewelry today is a form of iron pyrite. With its metallic luster and fiery sparkle, marcasite has also been called Fool's Gold. When cut with facets, marcasite shimmers like tiny diamonds, but is much more affordable.
Why is sterling silver used for Marcasite Jewellery?
Sterling silver is used in all Marcasite Jewellery as the darkness of the Marcasite stones compliments the light color of silver as well as its reflectivity. However, Marcasite and gold does not seem to have the same effect as the yellowish tint of gold tends to clash with the yellow brass tone of Marcasite which makes both minerals looks dull and ruddy. There are many jewelers who are working on overcoming this issue.
