I will confess that upon first glance, I thought this was supposed to be an abacus. Does this make me really old??

It is, in fact, a typewriter, which I should have recognized as I spend a fair amount of time in front of keyboard. Designed by Family Gold and for sale by Local Eclectic, it is made of the following: pearl, garnet, peridot, and iolite, set in 9k yellow gold and is a petite 12.8 x 9.6 mm.

Selling for USD$349, the site offers a lot more stacking options if your neck (or charm bracelet) is feeling a bit bare.
