The "queen of pearls" — unmatched size, exceptionally thick nacre, uniquely soft lustre.
Geographic origin
Northern Australia to Philippines, through Indonesia and Myanmar. Australia (Broome, Kimberley) is the most prestigious producer.
Pinctada maxima
Up to 30 cm, several kilograms. Silver-lipped: white/cream/silver pearls. Gold-lipped: champagne to deep gold — the rarest. 2-5 years cultivation.
Distinctive characteristics
Size: 9-20 mm, average 12-14 mm. Nacre: 2-6 mm thick (vs 0.3-0.5 mm for Akoya). Lustre: satiny, silky. Colours: pure white, cream, silver, champagne, gold.
Why golden pearls are the most expensive
True "deep gold" pearls are a tiny fraction of production. A pair of 13 mm deep gold round pearls is one of the rarest gems available.
In jewellery
A single 14 mm pearl on a fine 18k white gold chain — rare elegance, more striking than an ornate jewel.
