How to Know If a Ring Is Platinum

Platinum and white gold appear very similar at first glance. However, platinum is by far the more valuable. As a result, you may need to be able to determine if a ring is platinum rather than simply taking a vendor's word for it--particularly if you are not buying from a licensed jeweler. Fortunately, there are some fairly quick and easy ways to know if a ring is platinum.

Instructions

1

Compare the weight of the platinum and gold rings. Platinum is nearly twice as heavy as gold, so one ring should be clearly heavier than the other.

2

Check for a stamp. High-quality jewelry will be stamped with its make and metal. If the ring has a stamp inside that says 950pt or 850pt, then it is platinum (unless made by someone using a fake ring mold).

3

Scratch the metal using the edge of the diamond. If the ring is platinum, the diamond will leave a scratch with raised edges. The scratch will simply push the platinum to the side (the platinum can be restored). If the ring is white gold, the diamond will actually scratch chunks of metal out of the ring. You may need a magnifying glass to clearly discern what type of scratch you made. If you have not yet purchased the ring, it is unlikely that a vendor will be allow you to damage it. Factor in that you will likely have to make the purchase, then attempt to get a refund if the product is not as described.

4

Check for allergies. Gold rings are often plated with rhodium or bonded with a nickel alloy to make them harder. Both of these elements can cause skin irritation. If you have a history of psoriasis or eczema, then wearing these rings may cause skin irritation. However, platinum is safe for sensitive skin.
