Because platinum is a naturally white metal and hence, it doesn’t fade or change color, it’s becoming an increasingly popular choice for bridal rings. In fact, as the price disparity between this metal and gold is narrowing, some jewelers report that consumers are shifting their loyalties to platinum. If you’re considering a platinum wedding band, then remember that the metal’s density works best with a solitaire diamond. Before you rush out to the local jewelry store, here are 5 tips to know about.

• Verify the platinum jewelry hallmarking

First and foremost, you should make sure that the jewelry you’re about to acquire is actually platinum. The simplest way to establish this fact is to check the piece’s hallmark. The Platinum Guild International accredits reputable jewelers who sell platinum jewels. In addition, the pieces are also authenticated by a third-party certification issued by the UL Card. Never purchase a wedding band that doesn’t feature this hallmarking, because there’s a chance that the metal is not platinum.

• Ensure the seller has a buy-back policy

Platinum has only been recently added to the exclusive list of precious metals. Therefore, only very select jewelers have obtained the hallmark and are accredited to sell platinum jewels. Unfortunately, the limited number of sellers can impose stricter buy-back policies. Therefore, if you’re not satisfied with the style and design of the ring or you have simply changed your mind, then you might encounter some difficulties returning the platinum band.

On a side note, some stores don’t even accept to buy-back the platinum jewelry and only agree to exchange the item with another ring in their inventory. This is why it’s critical to inform yourself about this policy before purchasing from a certain dealer.

• Make sure the stone meets the 4 Cs

Once you establish you’re investing in a 100% platinum wedding band, it’s time to analyze the diamond stone. In general, you can determine the quality of the diamond and its price based on the 4 C parameters – cut, color, clarity and carat weight. Keep in mind that internally flawless diamonds are available at a 40% higher premium than the VVS diamonds. In addition, if you prefer a solitaire stone, then this is usually customized based on the order.

• Only purchase diamonds with certificates

Even if you are convinced you’re purchasing a quality diamond for your wedding band, you should make sure the stone comes with the appropriate certificate. You should be wary of jewelers who can only provide you with their own certification for the diamond. Unless the stone comes with internationally recognized certifications from institutions like GIA and IGI, you should not purchase it.

• If you’re buying as an investment…

In case you’re interested in acquiring diamonds and platinum jewelry as an investment, then you should know that only the latter constitutes an excellent hedge against inflation. As far as diamonds are concerned, investors view them as specialized products. Therefore, unless you’re an accredited jeweler selling diamonds or you are working in the trade, you won’t be able to make a profit from investing in these precious stones.
