From a single-strand Mikimoto cultured pearl necklace with its original box to a pre-1920 natural saltwater pearl necklace that has never been tested, we assess every piece with the distinction that actually determines value — natural versus cultured, lustre quality, string condition, and maker.
We buy pearl jewellery from private sellers, estate clearances, and jewellery collections across the UK. Identifying natural pearls — which can be worth ten to fifty times the value of equivalent cultured examples — is central to what we do. Free insured postage. Written valuation. Paid in 72 hours.
Pearl jewellery spans an enormous range — from genuine natural saltwater pearls of considerable value to cultured freshwater strands of modest worth, to glass simulants with no resale value at all. The honest answer to "what are my pearls worth?" begins with identifying which category they fall into, and that is something many buyers and general dealers do not take the time to establish. We do.
Natural saltwater pearl necklaces — formed without human intervention over many years in wild oysters — are among the rarest and most valuable items of jewellery. Pre-1920 necklaces are the most likely candidates for natural pearls, as cultured pearls were not commercially available until after Mikimoto's breakthrough in the early 20th century. Definitive identification requires X-ray or endoscope testing; we flag all necklaces that may be natural and advise accordingly. The difference in value can be dramatic — a natural pearl necklace can be worth £10,000–£100,000 or more.
Mikimoto — the Japanese pearl cultivation company founded by Kōkichi Mikimoto — is the name that commands the strongest premium in cultured pearls. Authentic Mikimoto necklaces are typically accompanied by original boxes with the clamshell clasp mark, and the pearls themselves carry distinctive high lustre and surface quality. Other named cultured pearl makers — Tasaki, Assael, and specialist British jewellers such as Mappin & Webb — also carry premiums over generic cultured strands. Provenance, original boxes, and clasp marks are all relevant to offer levels.
Matched pearl sets — necklace with earrings, or full parures including brooch and bracelet — are more valuable as sets than as individual pieces, provided the matching is genuine and close. Edwardian pearl and diamond sets in platinum are particularly sought: the combination of old mine cut diamonds, natural or early cultured pearls, and fine platinum work represents some of the finest jewellery made during that period. Victorian gold and pearl parures, while lower in metal value, carry collector interest for the period craft and design.
Pearl brooches range from simple pearl cluster brooches in gold settings to elaborate Edwardian and Art Nouveau pieces combining pearls with diamonds, enamel, and plique-à-jour work. The pearl is rarely the primary value indicator in a fine brooch — the setting quality, goldsmithing, and any diamonds are equally or more important. Antique pearl hat pins in gold and silver settings with freshwater or saltwater pearl finials have a modest but steady collector market. Victorian mourning brooches incorporating pearls (symbolising tears) are a specialist category within mourning jewellery collecting.
Pearl drop earrings set in gold or platinum are assessed on the quality of the pearl (lustre, surface quality, size), the setting material and quality, and any additional gemstones. Georgian and Victorian pearl drop earrings in closed-back gold settings are the most collectible period examples. Single pearl pendants on fine chains are assessed on the pearl quality and the chain independently. Baroque pearl pendants — particularly natural baroque saltwater pearls mounted as Renaissance-style figural pendants — can be individually significant pieces worth specialist assessment.
South Sea pearls — produced by the Pinctada maxima oyster in waters off Australia, Indonesia, and the Philippines — are the largest cultured pearls available, typically 10–20mm, with a distinctive silver-white or golden colour. Their size and lustre quality make them among the most valuable cultured pearls on the market. Baroque pearls — irregularly shaped rather than round — carry their own collector and design market, particularly large baroque Tahitian and South Sea examples. A single fine South Sea pearl can be worth more than an entire strand of standard cultured freshwater pearls.
The natural versus cultured distinction is the primary value divider and cannot be confirmed without testing. This is the single most important assessment we make — and the one most commonly skipped by general jewellers and cash-for-gold buyers. A natural saltwater pearl necklace inherited from a great-grandmother may look identical to an early Mikimoto cultured strand, but the values differ by an order of magnitude. Any pearl necklace from before 1930 should be regarded as potentially natural until tested.
Within the cultured pearl market, lustre — the depth and reflective quality of the nacre layers — is the primary grading factor. AAA-grade cultured pearls with exceptional lustre are worth several times those with dull or chalky surfaces. String condition affects value too: a necklace requiring restringing is still sellable, but the cost is factored into the offer. Clasp quality and age inform the assessment of the overall piece — a platinum Art Deco diamond clasp on a pearl necklace is itself a significant item. Finally, named maker provenance (Mikimoto box, hallmarked by a notable jeweller) consistently adds 30–60% above equivalent pieces without documentation.
The clasp is often the most informative part of a pearl necklace — it reveals the metal type, any hallmarks, and whether a maker's mark is present. Photograph it clearly alongside the full strand and any original boxes or pouches. Note if the necklace has ever been tested.

Genuine pearls (natural or cultured) feel slightly gritty or sandy; glass or plastic imitations feel smooth and glassy. However, this test cannot distinguish natural from cultured pearls, and high-quality glass simulants (Majorica pearls) can occasionally feel slightly textured. Surface temperature is another indicator: genuine pearls feel cool initially and warm slowly; plastic imitations warm quickly. For definitive identification, X-ray or endoscope testing by a gemmologist is required.
Natural pearls form entirely by chance when an irritant enters an oyster without human intervention — the oyster deposits layers of nacre around it over years or decades. They are extremely rare and typically command prices many times higher than cultured equivalents. Cultured pearls are produced by deliberately inserting a nucleus into the oyster — the nacre layers around it are genuine, but the process is managed. Mikimoto perfected the cultured pearl process in Japan in the early 20th century. Distinguishing natural from cultured definitively requires X-ray examination: natural pearls show concentric nacre rings; cultured pearls show a nucleus with a thin nacre layer.
Lustre — the deep, reflective glow from within the pearl rather than simply a surface shine — is the primary quality indicator in pearl grading. High lustre pearls have thick, well-organised nacre layers that reflect light in a way that creates depth. Low lustre pearls appear dull, chalky, or flat by comparison. Lustre can degrade over time through exposure to chemicals (perfume, hairspray, cleaning products), desiccation, or simply age. A necklace with degraded lustre may be worth a fraction of the same necklace in excellent lustre condition. This is why pearls should always be cleaned gently with a damp cloth only, and stored away from chemicals.
Age is not, by itself, a reliable value indicator for pearls — what matters is whether they are natural or cultured, their lustre quality, size matching, and any maker's mark or provenance. A Victorian or Edwardian pearl necklace may be natural (which would make it highly valuable) or may be an early cultured example or imitation. The clasp is often informative: a gold or platinum clasp with hallmarks suggests a quality piece; a base metal clasp suggests otherwise. Pre-1920 necklaces are worth having tested by a specialist before selling, as genuine natural pearl necklaces from that period can command five-figure sums at auction.
We buy individual pearl items as well as necklaces — pearl brooches, single pearl pendants, pearl drop earrings, hat pins with pearl finials, and rings set with pearls are all assessed. Pearl brooches from the Edwardian period in gold or platinum settings with fine pearls can be particularly valuable. A single natural saltwater pearl of significant size is a collectible item in its own right. Pearl parures — matched sets of necklace, earrings, and brooch — are valued as sets if matching is confirmed, and individually if the matching quality is approximate.
