When we mentioned the jewelry, we often think of the material of the jewelry, so many different
metals used in the creation of jewelry. Knowing some information about the different metals, their benefits compared with each other and their unique qualities you will be able to make a better and more informed decision find wholesale jewelry supplies about purchasing your jewelry wholesale.
When you wholesale jewelry , there are two things to consider when looking at gold. First, which gold carat to choose and second, the gold color or the combination of gold colors available.
The higher the proportion of gold used in the final metal, the more valuable and expensive the metal will be. So all other things being the same, an 18kt ring will be more expensive than a 14kt ring and a 14kt ring will be more expensive than a 9kt ring.
When choosing rehinestone jewelry, particularly rings, many people consider the hardness and durability of gold to be used in their ring.
Metal hardness is measured by what is called the Vickers scale where harder metals receive a higher Vickers score than less hard metals.
9kt has a Vickers hardness of 120 and 18kt has a Vickers hardness of 125. This shows 18kt as harder, but the difference is so slight that in practical terms 9kt and 18kt are much the same in terms of hardness.
There is another difference that should be considered when comparing 9kt and 18kt. 9kt is more difficult to bend and is a little more springy and therefore a fine 9kt ring may be less likely to bend out of shape than a fine 18kt ring. However, if the ring is of a good sturdy construction neither metal will be likely to bend out of shape.
Gold colors
Jewelry can also be made using a combination of different gold colors. These jewelry items are sometimes called two-tone, three-tone or multi-colored gold.
The gold content of yellow gold is measured in the same way it is measured in for example white gold. So an 18kt white gold ring contains 75% pure gold, just as 18kt yellow gold contains 75% pure gold.
As the color difference is due to the metal components in the alloy mix, the color of yellow gold and rose gold will not chip, fade or wear off with age.
Yellow gold is made by mixing pure gold with alloy metals such as copper and zinc.
Rose gold is made using a mix of pure gold with alloys including copper. The copper provides the rose-reddish color.
The 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.
As each gold color contains the same proportion of pure gold all gold colors with the same carat weight when measured on the Vickers scale have the same Vickers score.
