Check the listing for details. FLUORESCENT : HACKMANITE (cabinet piece) - Davis Quarry - Bancroft , Ontario. Condition: Used, Made in United States. Listed at 150.00 USD. Hackmanite in nepheline syenite. The fluorescence of the hackmanite is best seen under long wave. The syenite fluoresces blue/white under LW. In my opinion, hackmanite is one of the best and most economical LW fluorescent minerals on the market!
