SECONDS 20mm round glass bubble dome cabochon, rounded bottom

SECONDS. These were supplied to us badly packaged, and the surface of some of the cabs has been marked by being up against the other cabs. These domes are great for practising with, or kids classes, or when a bit of a scratch doesn't matter. Now massively reduced!

Note: These 20mm cabs have a slightly rounded edge on the bottom, which makes them sit up higher than the original flat bottomed ones. They are fine in a high sided bezel setting, but don't sit right in the almost-flat settings.

About the Grading system for the Glass cabochons:

• A-Grade - clear with no visible scratches or marks.
• B-Grade - may have small marks on the bottom or small cracks on the edges, these generally don't show when inserted into a bezel setting.
• C-Grade - small scratches on top, insignificant but there.
• Seconds - with scratches on top, ideal for practising with, or kids classes, or for 'vintage, grunge or rustic', when imperfections are part of the design!
• M - 'mystic', the glass is not crystal clear.
• R - rounded bottoms, these domes are not suitable for using in bezel settings with low side edges, but are ideal in high-sided bezels, or crown edge and filigree edge settings.
