Finger Mate is a renowned company that has been providing the finest expandable ring shanks since 1964. Their innovative shank design allows rings to open three sizes larger to fit comfortably over the knuckle, and then locks securely in the wearing position, eliminating the need for twisting and forcing rings on and off.
With a two-position locking mechanism and a 14K gold special safety spring, Finger Mate shanks ensure a perfect fit and offer the option to open the ring approximately half a size larger while still locked. Available in a variety of styles and widths, their expandable shanks are made exclusively of 14K white gold, 14K yellow gold, or platinum, guaranteeing both safety and durability.
