4g gauge earrings 5mm glass ombré

Glass ombré clear to blue in pre loved condition. See photos of size next to business card of charts.. been hoarding since my stretching days so I worn them only a few times.. my best guess is 4g 5mm .204”.. I know I have them next to 2g measurement but when you pop them through your ears they fit the 4g measurement. Please go ahead and offer I’m not set on these prices if would rather see them sell and be used.
