31mm. Shank has an opening of approximately 2-2.5mm.
Beautiful pressed Czech glass relief button. Large buttons are great for jewelry focal points (especially Kumihimo), fiber accents and more. They do not have to act as a closure, but can
be strategically placed to make your garment or craft even more
This button has a "amethyst AB matte finish", which means the color varies from purple to green to blue to cream in different lighting.
