Fist time I found a button with a stone in it, any idea what the stone is made off. Also found a bunch of colonial flat buttons and a couple worn Hibernias. The brass thing, looks like it may be the spout of a colonial powder flask or something.
congrats on the unusual button its more then likely a "paste" stone .
The term paste is used to refer to gemstones made of various kinds of cut glass. Lead glass was most commonly used, since the denser the material, the higher the refractive index and the greater the dispersion.
Ive seen a lot of buttons on here but never one with a stone in it! Excellent find...Can't tell if it was put in there when it was made or sometime after
Nice going on the button and the first of this type I've seen. Wonder if could of been a collar stud or one end of a cufflink something that gives it a little more dress up factor?
some great finds, I am about 100% certain that you have a Powder Flask spout there. I see what looks like the little latch that was on the spring closure. Your button is cool too, I found one a few years back from a colonial site with a blue stone in the center. Yours and mine are the only 2 that I have seen posted here on TN, there may be some others but I haven't seen them.
