Product Description
This parcel is of 100% natural Hackmanite and Sodalite rough stones in untreated, mined condition. The total weight is 50 carats. There are 16 pieces ranging from under 1 carat up to approximately 7.7 carats per piece. This lot is sourced from Afghanistan. The parcel is start-up deal for lapidary buyers and collectors.
The color of hackmanite is off-white, white, light blue, and occasional faint violet hints. The clarity is ranging from semi-transparent to translucent and some stones showing natural inclusions.
Why This Hackmanite Lot Is Special?
Hackmanite is a rare sodalite variety known for tenebrescence—a natural UV-reactive color change. Under UV light, the stone can darken or shift tone and then slowly fade back in normal lighting. This makes Hackmanite highly desirable for collectors, lapidary hobbyists, and buyers who enjoy UV mineral testing.
What Lapidary & Cutter Can Get from the parcel?
The pieces have mixed transparency. Some stones may be used for small faceting trials, but overall this is best positioned as lapidary rough for transluscent faceted stones, cabochons specimen pieces, and UV testing. Expect natural inclusions and fractures typical of Hackmanite material. Some pieces show color zoning and surface staining that can often be reduced during trimming.
Best uses: semi transparent or transluscent loose stones, cabochons, small fantasy cuts, carvings, specimen displays, UV mineral content, and lapidary practice. See UV Reactive Gemstones.
