Sydhavspärlor

South Sea pearls, or Sydhavspärlor, are cultivated pearls produced by the pearl oyster species Pinctada maxima in the warm waters of the South Pacific. The two recognized varieties are the silver-lipped and the gold-lipped oyster, named for the color of the inside of their shells. Pearls from these oysters are among the largest in the world and are notable for their thick nacre.

Appearance and quality: Sizes commonly range from 9 to 20 millimeters, with exceptional examples surpassing 20 millimeters. Shapes vary from round and near-round to baroque. Colors span white, ivory, and gold, with natural hues often preferred for their depth. The thick nacre gives a high luster and good durability, and surface quality is a major factor in value.

Production and geography: Cultivation involves implanting a bead nucleus and mantle tissue into the oyster, with growth taking several years. Major farming regions include Australia (especially Western Australia and Queensland), Indonesia, and the Philippines. After harvest, pearls are sorted by size, shape, color, and luster, and may undergo minor surface treatments to enhance appearance.

History and market: South Sea pearls began to be cultivated commercially in the early 20th century as the industry expanded in the South Pacific. They are highly valued in fine jewelry for their size and luminous appeal. Natural South Sea pearls are extremely rare, making cultured specimens the standard in the market.

Sustainability and regulation: The pearl industry is governed by national aquaculture regulations and increasingly adheres to international standards for responsible sourcing. Producers emphasize environmental stewardship, water quality monitoring, and oyster health to minimize ecological impact.
