A rare group of natural Barite faceting rough from an old private collection, representing three distinct localities and color varieties. The golden yellow is from Tuscany, Italy; the pale blue from Colorado, USA; and the deep cognac-colored rough from Russia.
Barite is notoriously challenging to facet—its perfect cleavage and relatively low hardness require a steady hand and precise control. Even minor pressure during dopping or polishing can cause splitting, which is why few cutters attempt it today. When successfully finished, however, Barite reveals a luminous, watery brilliance unlike any other gem material
An uncommon, beautifully matched old-stock group representing three countries and an era when collectors still cut and studied unusual minerals for their optical beauty
3 pieces / 9.347 grams / 46.735 carats / 15+ carats average / Some inclusions but good rough worth cutting
Estimate: $375 - $425
