💫 Speckled-stone lore and care
“Dalmatian Jasper” is a widely recognised trade name rather than a precise mineral classification. Classic material is strongly associated with Chihuahua, Mexico, but appearance alone cannot prove locality. Bright blue, teal, pink or purple pieces are usually dyed, while claims that the black spots are Tourmaline should be treated cautiously—the dark grains in classic material are commonly arfvedsonite-rich amphibole.
Dalmatian Stone is approximately 6–6.5 on the Mohs scale and generally polishes well, although edges may chip along boundaries between different mineral grains. Clean it briefly with lukewarm water, mild soap and a soft cloth or brush, then dry thoroughly. Avoid bleach, acids, solvents, abrasive powders, strong heat, steam and ultrasonic cleaning, especially for dyed, fractured, filled, glued or visibly pitted pieces.
