American Machine-Made

JABO Classics

JABO marbles are modern machine-made runs, many with aventurine or oxblood-look accents produced in identifiable batches.

What to look for

  • Sparkle from aventurine is the usual draw.
  • Run character matters more than age in this family.
  • Condition is generally high — grade strictly.
