Large and somewhat heavy. Very pretty.
I got this at the same time as I got a Moderne Monocle necklace. For me, the Moderne Monocle (the other one) is used by holding it up a few inches from your eye, and you can see a whole page about 12 inches away.  THIS lovely necklace requires me to hold it further away, at the maximum of its chain, and I can see only a small circle of part of a page.  I suspect it has something to do with the "prescription" for your reading glasses.  I am a 2.5.
