GIA recognises four major types of cultured whole pearls — akoya, freshwater, Tahitian and South Sea[4] — and each behaves differently at wholesale: different price architecture, different matching risk, different margin profile. For a jewellery brand or retail buyer building a collection, the type decision is a merchandising decision. Hong Kong, the world's largest exporter of pearls in 2025[6], is where much of this stock is traded — the majority imported from Japan, the Chinese mainland, Australia and India[6]. This guide compares all four types from the wholesale buyer's perspective.
| Akoya | Freshwater | Tahitian | South Sea | |
|---|---|---|---|---|
| Primary source | Japan; China also produces[4] | China — the leading source[4] | French Polynesia[2] | Australia, Indonesia, Philippines[2][4] |
| Typical size | 6–9+ mm; rarely over 9 mm[2][3] | 6–16+ mm[2] | 8–14 mm[2][3] | 9–16+ mm; the largest type[2][3] |
| Signature colours | White to cream, rose overtone[2] | White, pink, peach, lavender[2] | Natural darks: grey, green, brown[2] | White, silver, golden[2] |
| Luster character | High, mirror-like[2] | Soft to high[2] | Satin to high[2] | Soft, satin glow[2] |
| Wholesale value tier | Mid-range to high[2] | Generally most affordable[2] | Mid-range to high[2] | High[2] |
Cultured in the Pinctada fucata oyster and typically under 9 mm[3], akoya is the classic white pearl of the single-strand necklace, prized for sharp, mirror-like lustre[2]. Wholesale relevance: akoya supports classic, wedding and corporate lines where roundness and lustre consistency are the product. Expect tighter sorting and higher per-mm price steps than freshwater.
China is the leading source of freshwater cultured pearls[4], which GIA describes as the most commonly produced and among the most popular types with designers, thanks to a remarkable range of sizes, shapes and colours at lower price points[4]. Wholesale relevance: freshwater carries entry-price jewellery programs, and its shape range (near-round, oval, baroque) supports fashion-forward designs where perfect roundness is not required.
Tahitian pearls are cultured in French Polynesia and are known for natural dark bodycolours — grey to silver to brown — often with trade names such as peacock, aubergine and pistachio[2][5]. They are not dyed black; the colour range is naturally occurring[2]. Wholesale relevance: Tahitian stock differentiates a contemporary collection, and the most common diameters run 9–11 mm[5], convenient for pendants and studs. Note that GIA places typical Tahitian sizes at 8–14 mm[2][3].
Grown in the largest pearl oyster (Pinctada maxima) across Australia, Indonesia and the Philippines, South Sea pearls are the largest of the four types — typically 8–18 mm — with thick nacre from a long growth period, in white, silver and golden bodycolours[2][3][4]. Wholesale relevance: South Sea anchors high-ticket statements; Australia is the largest producer[5].
Buying pearls wholesale is a different discipline from buying retail:
A Concept Group Limited — founded 2015, family in the pearl trade since 1986 — wholesales akoya, freshwater, Tahitian and South Sea pearls from Hong Kong, with a Hong Kong Tahitian Black Pearl Association membership behind its Tahitian line.
