Use this guide to learn how to change your
ring size by using a ring guard.
School Ring Guards are perfect for allowing
rings to size down up to 3 full sizes smaller. They are typically used on
larger size rings that need to be dramatically sized down. The name
"school" ring guard comes from the idea of a high school boy giving his
class ring to his
sweetheart for her to wear as a symbol of their special friendship.
"Makes his ring fit her". This method of ring sizing is
semi-permanent and the ring sizer can
easily be removed from the ring with the use of a pliers.
You must first measure your ring so you know
which size school ring guard you need to fit your ring. Take your ring
hold it in your hand so that the bottom
of the band or the portion of the band that usually sits on the inside of your
finger is facing out. Grab your digital gauge in your free hand and open
the jaws wide enough to fit on either side of the outside of the band and then
close the jaws around your ring band and record the millimeter measurement of
Since there are 3 available sizes for the school ring guards, each size will
fit a different span of band widths and size rings various amounts. Take your
measurement and see where it fits on this chart:
Small Size: will fit a 2.65 mm up to a 3.45 mm wide band. Ring guard
width is 2.60 mm. The small size has a bridge (bar) that will fit the span
of a ring sizes from sz.7.5 to 9.5
Regular Size: will fit a 3.45 mm up to a 6.0 mm wide band. Ring guard
width is 3.40 mm. The regular size has a bridge (bar) that will fit the
span of ring sizes around sz.10 to 11.5 .
Large Size: will fit a 3.45 mm up to a 6.0 mm wide band. Ring guard
width is 3.40 mm. The large size has a longer bridge (bar) in order to fit
the span of larger ring sizes from sz.12 and up.
Once you have your school
ring guard in hand you can install it into your ring. Holding your ring upside
down, place the ring guard inside the band with the smooth side facing up toward
the top of the ring and the shorter prongs resting inside the band.
As you push the school ring guard into place
inside the ring, the shorter prongs should bend to fit smoothly against the
curve of the ring.
Then, holding the ring
guard inside the band, take your jewelers pliers and fold down the two prongs on
one side of the band so they close around the band. They should hold the band
securely but not scratch the metal.
Once you have folded the prongs down on one side of the band, turn the ring so
you can fold the remaining two prongs down and around the band. These prongs
will keep the ring guard from shifting while you were the ring.
Now that you have secured
the ring guard in your ring, you’ll need to try it on.
If your ring is too small now, you can take the ring off and push the middle bar
down towards the bottom of the ring band until the ring fits. Continue trying on
the ring and pushing the bar down until it fits just the way you want.
Once your ring fits again, you can continue
wearing it without fear. To learn more about ring guards and how to
