  • A striking specimen featuring a single, well-formed cobalt-blue celestine crystal rising from a bed of creamy orange calcite. The celestine crystal is prismatic, measuring 3.2cm in length, with a rich blue color and glassy luster. The matrix consists of delicate, snowball-like formations of calcite crystals in peachy-beige tones, creating a dramatic color contrast with the deep blue celestine.

ABOUT THE SPECIMEN

When celestine specimens from this location hit the market a year ago, they instantly became known as some of the finest contemporary examples of the species. Few localities worldwide can boast the same alluring blue that these ones have, derived from a lattice-defect phenomenon. The crystal here is thick and measures 3.2cm in length, sitting beautifully on a sculptural background of beige to yellow-orange calcite. The only flaw I can see is a missing crystal that grew along the main one, and even this doesn't detract from it too much in my eyes. Balanced, attractive, and a fine example of material that is getting harder and harder to find on the market.

MORE INFO

Badghis Province sits within the Afghan-Tajik Basin, a thick sequence of Mesozoic and Cenozoic sedimentary rocks including the evaporite-bearing carbonate horizons that host the Darai Laman deposit; celestine's occurrence in limestone here fits the standard diagenetic model in which strontium preferentially partitions into strontium sulfate rather than calcium sulfate during evaporitic concentration. Blue coloration in celestine is an intrinsic lattice-defect phenomenon rather than a trace impurity, and Darai Laman material tends toward a notably saturated cobalt to deep sky-blue that compares favorably with the best Sicilian or Madagascan material. Crystals form short prismatic to tabular individuals, typically on straw-yellow scalenohedral calcite matrix - the color contrast between the two phases being the defining aesthetic of the locality. Material first entered Western dealer networks in meaningful quantities around 2010 and has continued appearing intermittently since, with a documented find in 2022 confirming the deposit remains accessible. Given Afghanistan's ongoing political constraints, supply is entirely dependent on export chains that can close unpredictably, and the locality remains considerably less known internationally than the quality of its material warrants.
