A platinum engagement ring has become the preferred ring of choice because it is the purest metal compared to its counterparts.
Moreover, platinum is the easiest metal a jeweler can work with due to its pliability and softness. What makes platinum so pliable? Simply put; the elements such as palladium as well as ruthenium, iridium, rhodium, and osmium contained therein. Two of the elements, iridium and ruthenium, contribute to the heaviness of platinum as opposed to other metals.
Another feature one can find when purchasing platinum rings is there is no allergic reaction and the skin does not discolor as it would with other metals. Investing in a platinum engagement ring not only ensures its value will remain high, but it will last longer due to its durability.
The process by which a jeweler will use the prongs of the ring to encase a diamond is an easier task due to the size of the prongs. They hold the diamond quite securely; and there is no need to worry about a diamond loosening or becoming worn over time. In fact, little if any damage usually occurs to a platinum engagement ring as long as it is properly cared for.
Considering the price of gold these days, one would not be too surprised to learn that gold does tend to wear over time. However, this is not the case with platinum. Is white gold the same as platinum? Not really. White gold may turn yellow over time. In addition, while platinum is a harder metal, the prongs in white gold rings can break because it is more fragile.
While there are a myriad of platinum engagement ring settings available online, it would be prudent to purchase a platinum ring at a jeweler who is also a licensed gemologist. In this way, you can obtain a certificate outlining the cut, carat, clarity, and color of the diamond you choose to set in the ring.
In addition, when selecting a platinum ring you may wish to decide what setting is appropriate as well. For example, would you prefer a 6-prong, solitaire, or cathedral setting? The websites that offer these settings can be of tremendous help in making a decision.
Platinum jewelry, in and of itself, can be viewed as classy and elegant; whether it's earrings, bracelets, or a platinum engagement ring. As mentioned earlier, choosing this type of ring has an increase in value over time, has proven durability, and is a soft metal that will offer years of enjoyment.
