A. You have found a “flower frog,” popular in the 1920’s and 1930’s and used to arrange flowers. They are still produced today, and can be found in many styles and made out of all different types of materials, including glass, pottery, lead or bronze. Some have holes in them, some are cage-like, and some have metal spikes or “hairpin” loops which hold the stems in place. They were also produced in many shapes, and while this one is a simple round shape, some are very elaborate and may have a figure attached to it. The largest manufacturer of glass frogs in the United States was the Cambridge Glass Company from Cambridge, Ohio. If yours does not have a stamp or marking, there is a chance it predates 1875.
While not all that valuable, there are plenty of people who collect them (Martha Stewart being the most famous). There are clubs for collectors and many books on the subject.
