Designed and crafted in the U.S.A. by California glass artist Mark Black

This one-of-a-kind borosilicate glass marble measures 31mm in diameter (1.2").
Made with durable PYREX for years of enjoyment. Kiln-fired & annealed for structural integrity. Click on the photos above for a 360° view.

Internal features: shimmering dichroic swirls in a fluid vortex of emerald/gold colors, encased within a magnifying window. Small bubbles add sparkle and interest.

Surface work: a small patch of sparkly blue/green unobtanium lends contrast to this marble & helps bring out the dichroic bling.

Discreetly signed with my initials and the year the piece was made: MB 08, using an indelible titanium scribe. This ensures you'll have an original, collectible piece of artwork.

Thank you for supporting a small business owned & operated by independent glassblowers.
