South Sea – The Most Valuable Pearls in the World

Why South Sea pearls are the most precious in the world

Golden South Sea pearls are among the largest, most spectacular, and most valuable pearls in existence. A necklace can cost from $10,000 to $300,000. They are cultivated in the giant mollusk Pinctada maxima, with its golden-lipped shell. Their rarity and sensitivity make cultivation extremely challenging and far more expensive than other saltwater pearls.

Why are they the most valuable pearls?

South Sea pearls have a very thick nacre layer – 2–4 mm – and the longest growth period, up to 4–5 years. While Akoya pearls take 2–3 years to form, South Sea pearls require 377 steps to reach ideal size.

They are the largest saltwater pearls: 8–10 mm Akoya pearls are considered large, while for South Sea this is average. Exceptional pearls can reach 16–18 mm and are found only in elite private collections.

One of the rarest strands took 37 years to collect – 35 giant pearls of 18 mm, grown in the pristine waters of Palawan.

Value also depends on color: from white-silver to light gold and deep golden hues, with the most valuable resembling 24-karat gold.

The science behind the beauty

The luster and color are created by layers of aragonite crystals and conchiolin. The denser and more compact these layers, the more intense the pearl’s glow and overtones.

Where do they come from?

White South Sea pearls are mostly from Australia, while golden pearls come mainly from the Philippines and Indonesia. Exotic waters add to their beauty.

In the 1850s, Broome, Australia boomed during the “pearl rush.” Today, a museum honors this legacy. Mature South Sea pearls are sold at auctions in Japan and Hong Kong only a few times a year.

What are inclusions?

Natural marks left on a pearl’s surface – small spots, growth rings, or nacre irregularities. Fake pearls have flawless surfaces; real ones always show uniqueness.
