Pure gold is too soft to withstand the stresses of everyday use, so it combines with different alloys to give it strength and durability. These alloys include metals such as silver, copper, nickel and zinc. Well, the quick answer is that platinum is harder because it's denser and more durable than gold, which is actually a naturally soft metal. However, you might be surprised to learn that platinum is more easily scratched than 14-karat gold.
When platinum is often advertised as the best and most durable metal, how could it be if it's scratched more easily? It doesn't always make sense at first, so let's dive a little deeper. Although both gold and platinum are strong and durable precious metals, platinum is the more durable of the two. This is the result of platinum's extreme density and chemical structure. For example, the tips that hold the center stone of a platinum engagement ring are less likely to break than those of a gold engagement ring.
Quite clean, right? Platinum's density means it will take longer to wear out than gold. In addition, its chemical structure means that when someone hits a platinum ring, the metal only moves, rather than being scratched. Gold is a very timeless and durable metal that does not rust, corrode or tarnish. Jewelers of all ages have preferred gold to all other metals because of its lustrous beauty and the ease with which it is possible to work on beautiful and timeless designs.
It can be alloyed with several other metals to increase their strength and produce a variety of colors. . Since pure 24-carat gold is considered too soft for the manufacture of jewelry, Adiamor makes all of our jewelry in 14-carat, 18-carat and 19-carat white, 14-carat and 19-carat yellow and 18-carat rose gold. For all these reasons, the trio of gold, silver and platinum continues to enjoy considerable popularity as metals for jewelry.
A common practice, for example, is to coat parts made of less expensive metals with thin layers of gold. Gold carat brands are usually only 14 carats, 18 carats or 19 carats; however, it is also quite common to find the numbers 750 and 585.These three-digit numbers refer to the approximate percentage of pure gold in the alloy mix; for example, 750 equals 18 carats because 18-carat gold has a purity of 75%, while 585 is the standard value of 14 k, since this karat blend contains 58.5% pure gold. If properly cared for, gold can last indefinitely, making it a precious metal for designers and consumers alike. Therefore, jewelers usually send old gold to a refinery instead of smelting and re-melting a new item in their workshops.
According to the theories of the time about the origins of metal, they believed that it was “immature gold” and therefore unusable. As mentioned earlier, platinum will always remain white, but white gold must be re-polished and re-plated from time to time to avoid a yellow tint. There is only one platinum mine for every 10 gold mines, making platinum one of the rarest metals in the world. While jewelers use pure gold for some pieces of jewelry, they dent and show wear so easily that most people don't wear pure gold jewelry regularly.
Recent studies suggest that gold originated in the far reaches of the universe billions of years ago. However, one important thing to keep in mind is that when gold is scratched, gold is lost (and looks like a scratch). Gold is a heavy metal (density 19.3 g cm) and one gram of gold can be molded into a thin sheet of gold of one meter in area and only about 230 atoms thick. Since solder must have a lower melting point than the parts it joins, it mixes with metals with lower melting points than gold.
Rhodium is often used as a non-shining coating for white gold, silver and other platinum group jewelry metals. .
