Expandable ring shanks
Open and lock securely for a perfect fit

The Finger Mate expandable ring shank opens wide to easily go over the knuckle, then closes and locks securely in the wearing position. To open, simply grasp the top of the ring and pull up.

No more twisting and turning.

No more forcing rings on and off.

Finger Mate shanks are available as findings or factory installed, in a wide variety of widths and styles, in 14K white gold, yellow gold or platinum, to replace the shank of almost any ring.

The Finger Mate shank replaces your existing shank to allow your ring to open three sizes larger to fit over your knuckle, then locks closed in the wearing position. The expandable ring is easy to put on, slide over knuckle,  easy to remove and comfortable while worn.


No more twisting and turning.

No more forcing rings over the knuckle.


The Finger Mate shank opens automatically when the ring is pulled from the top and locks closed when its sides are squeezed together. Its 2-position catch allows for an approximate half-size adjustment when needed. There are no buttons to push, and no dangling flaps. The 14K gold special safety spring allows the shank to open 3 - 4 sizes .





What is a expandable ring shank?

The shank of a ring is the lower part, the part that is generally not seen unless the ring twists and spins on the finger.

A ring with a conventional fixed shank must be made large enough to go over your knuckle (finger joint).  This makes the ring too large in the wearing position, causing it to twist and turn on your finger.

Can any ring be fitted with a Finger Mate expandable ring shank?

Finger Mate expandable shanks are available in a wide variety of styles and widths to accommodate almost any ring. 

What is it made of?

Finger Mate expandable shanks are made exclusively of 14K white gold, 14K  yellow gold  or platinum. No steel springs or other base metal is ever used in our shanks.

Is it safe?

Absolutely! The two-position locking mechanism provides the closed finger size and also an option to open the ring approximately a  1/2 size larger - while the ring is still locked. Furthermore, a concealed spring prevents the ring from opening too far. There is always a continuous band surrounding the finger.
