GEM NEWS: Argyle Pink Diamonds Get International Advertizing Push

Have you noticed on the Internet almost everywhere there is an advert for Argyle pink diamonds? This is part of Rio Tinto's push into the global market. The Australian diamond industry recorded a growth of 24% in 2013 and further growth in 2014 (Ibisworld). Biggest demand is from the US, followed by China and India.

The Rio Tinto's Argyle Mine in Western Australia produces more than 90% of the world's supply of pink diamonds. They are cut and polished in India and mostly sold in Antwerp.

Several companies specialize in selling pink Argyle diamonds, James Allen and Leibish Co being notable. Check what they have on hand for that special gift at Leibish Co.

Amber Crafts

Colour of Mexican amber varies between clear yellow, cognac, red, cream and black. Clear yellow amber with insect inclusions is highly prized for pendants and display specimens. Polished amber pieces are set in silver jewelry. Local silversmithing is excellent with the usual range of pendants, necklaces, cabochons in rings and earrings. Large pieces, 6 to 10 cm size, are carved into figurines, birds, animals, frogs etc. Some expensive necklaces have amber combined with either lapis lazuli or jade. Much of the low cost amber for sale on street stalls is pressed amber, made by heating under pressure small, otherwise useless fragments.
