全部拍賣 / Ethnographic / Larimar 2 x stud earrings- 1.44 g - (2)
2 Larimar stud earrings / cabochon / new Set in 925. Sterling silver Total weight: 1.44 g / 4.2 ct 6.9 mm x 5.0 mm x 16.7 mm New and unworn Larimar is a blue-white banded variety of pectolite, which has so far only been found at two locations: in a metamorphosed ultrabasic volcanic rock on the Barahona Peninsula in the Dominican Republic and at “Fittà” near Soave in Italy. Larimar has nothing to do with the blue amber that also occurs on Hispaniola, which is sometimes processed in the same operations in Puerto Plata and in the same way as pectolite. Larimar was only discovered in 1974 (the claim that Larimar was already known to the island's indigenous people is a legend) and has been commercially used as a gemstone since the early 1980s. Compared with white pectolite, Larimar is harder (up to 6 on the Mohs scale) and occurs exclusively in dense, fine-crystalline aggregates. The sky-blue color is due to small traces of vanadium (not due to copper, as there are copper-free Larimars); in addition there are greenish varieties, whose color is presumably due to lattice defects. Shipping as insured registered mail.
