Notes - Marlborough green chalcedony / chrysoprase was wiped out by the high-end jewelry industry and collectors in the 1970's due to it being a dead ringer for the highest-end jadeite (Imperial to Apple Green) hardness is excellent and pieces of this vintage jewelry even with conservative amounts of the chalcedony and no diamonds, set in platinum or gold single cabs in this top color and translucency.A true investment gem.
