If I can, I always try to do the stretch to size up,
especially when there are stones already set and I don't feel
like pulling them.
Hello Glen:
I often size rings, with heat sensitive stones, up and
down.Simply buy clamping in my third arm and submersing the ring
half in a crucible filled with water.You must use a much hotter
flame,but it beats removing stones.
We are a on line mail order catalog and we ship to the usa, western
europe, Australia , Japan etc. We got a request as to how do you
compare ring sizings in England and they use letters eg, i j k and
In canada we use eg. 7, 71/2 , 8 etc, The question asked mw was
what letter corresponds to what number ring size? I would really
like to get this
Finn, The info you require as well as a great deal of other useful
stuff is in a book called “Jeweler’s Resource” by Bruce G. Knuth. . .
.published by Jewelers Press. It gives ring size equivalents for
North America, Japan, France, Germany, Britain etc. I’m assuming you
could buy it online…say at Amazon.

Regarding the comparative sizes of rings in different countries,
there is a very clear graphic illustration of several different ring
mandrels in my book, Ring Repair. You can see that illustration by
