Jewelry stores are in the business of making money just like another business in the world. They wish to offer you quality services and products that will withstand test of time. After all, they may be no different than any other business in that they experience return customers and repeat business. The concept is simple really. Through putting out a product they're confident in, people will be satisfied with their purchases and wish to return to do business again. When your jeweler voices a concern about several aspect of your style, he or she is not being rude or uncertain in his capabilities as a professional, but instead he simply wants you to be familiar with any problems this kind of design could cause a person down the road.
For instance, people have been raving concerning "black gold" recently. They see pictures on the internet of those lovely black/grey metal bands used in a variety of jewelry. It appears as though a great and creative thought for their ring or any other such piece of jewelry, however it is actually kind of high maintenance! Maybe the saying is true, "The prettier it's, the more pain it really is!" Black gold does not exist. Instead, this is regular white gold that has been dipped in to rhodium to create a plating of a various color around the group. Eventually, this colour will wear aside and the white gold will probably be exposed, making your own jewelry completely change in color.
Although this specific color is achievable from a az jewelry store point of view, it will involve plenty of maintenance to keep it looking black. In case you are willing to be without your own ring for a few days another month, then by all means style this ring. It truly will be one of a kind!
