What Does "10k RGP" on a Bezel Mean?
If a bezel is identified as "10k RGP," it means the metal plating is 10 karat rolled gold-filled. This type of layer contains less gold than solid gold or gold-filled items. A 10k rolled gold-filled covering is at least one-fortieth the weight of the entire piece of jewelry.
Although rolled gold-filled plate is not as lustrous as more dense gold, it is sturdy and should not wear off easily. Jewelry identified as 10k RGP is typically within a mid-price range.
The bezel of a ring is a collar that holds the stone securely in place. In some styles it completely surrounds the gem, while in others the bezel covers a part of it.
