Denmark Turquoise Marriage Fashion Jewellery Earring Necklace.
By Aamir Mannan.
Turquoise is nearly always cryptocrystalline and massive and assumes no definite external shape. Crystals, even at the microscopic scale, are exceedingly rare. Typically the form is vein or fracture filling, nodular, or botryoidal in habit. Stalactite forms have been reported.
