Hello Raakhi. Since you seem a little confused..... There are a few
rings that just cannot be sized - tungsten carbide, for instance.
Just about any other ring in the normal world can be, one way or
another. The question is, what is that way? There's no way to know
that exactly without seeing the actual ring, and what's to be done.
Size up? Down? How much? and when you say filagree, what does that
mean? Many people use the word for simple fine piercing. Sometimes
you'll just have to live with a place where it's sized that's neat,
but different from the pattern. Engraving can always just be
re-engraved, if it's on the outside - not some message on the inside,
though. Sizing balls are a generic term for things that are soldered
on the inside of the ring to tighten it up - sometimes it's 2 little
balls at 5 and 7 O'clock, sometimes it's a small bar of gold, and the
ultimate is a 3/4 ring of spring gold soldered inside. They are not
actually intended for sizing, though they work, somewhat. They are
more for arthritic knuckles or just big knuckles, so the ring doesn't
spin after it's on. I'd suggest finding a quality jeweler, and have
sized properly, if necessary. You'll be happier in the long run...
And, you never know, it just might fit out of the box...
