Abstract
Improved crimping ring, characterized by comprising three arms of a certain length, in order to achieve greater elasticity, to exert pressure on a spherical stone that adorns the ring through three claws in which the aforementioned arms end and prevent the spontaneous exit of the stone whose extraction is easy, it is enough to exert a pressure with the fingers towards the outside, being able to be substituted by another one of different color being enough for it to exert a new pressure this time towards the interior previous support of the stone on the three claws.
