Understanding pearls, honestly.

Pearls are described by a small set of quality factors, a separate group of colour characteristics, and clear product disclosure. We treat these as three different things so that nothing is implied that we cannot support.

Pearls are organic gems formed through life, time and layers of nacre. Their beauty is gentle rather than loud, and their value lies in lustre, surface quality, shape, colour, nacre quality, size and matching.

A meaningful gem

Pearl: The June Birthstone

Pearl is traditionally known as one of the birthstones for June. It is also widely associated with elegance, softness and timeless femininity, making it a meaningful choice for birthdays, anniversaries and personal milestones.

Pearl is also traditionally associated with the 30th wedding anniversary.

Quality, in plain language

How We Describe Pearl Quality

Lustre / 光泽

The brightness and sharpness of light reflected from the pearl surface.

Surface Quality / 表面光洁度

The visibility of marks, spots, bumps or blemishes.

Shape / 形状

Round, near-round, oval, drop, button, baroque or other forms.

Colour / 颜色

The body colour of the pearl.

Overtone / 伴色

A subtle secondary colour seen over the body colour.

Orient / 晕彩

A rainbow-like iridescent effect seen in some pearls.

Nacre Quality / 珠层质量

The quality and thickness impression of the nacre layers, which affect beauty and durability.

Size / 尺寸

Usually measured in millimetres.

Matching / 匹配度

Important for earrings, strands and jewellery with multiple pearls.

Not every pearl shows strong overtone or orient. These effects vary depending on pearl type, nacre quality and light interaction.

Pearl Types

A short introduction to the varieties we describe.

Akoya Pearls

Akoya pearls are admired for refined lustre and classic elegance. They are often associated with Japanese pearl jewellery.

South Sea Pearls

South Sea pearls are known for larger size, soft luxurious lustre and a strong presence. Golden South Sea pearls are commonly associated with warm golden tones.

Tahitian Pearls

Tahitian pearls are often called black pearls, but their colours may include grey, green, peacock, aubergine and other rich overtones.

Freshwater Pearls

Freshwater pearls offer a wide range of shapes, colours and sizes. They are versatile and suitable for many jewellery designs.

Edison Pearls

Edison pearls are bead-nucleated cultured freshwater pearls, often admired for larger sizes and rich colours.

Mabé Pearls

Mabé pearls are blister pearls usually formed against the shell. Their smooth domed form is often used in earrings, pendants and rings.

Conch Pearls

Conch pearls are rare non-nacreous organic gems, often admired for pink colour and flame-like structure.

Pearl Care

Gentle care for an organic gem.

Pearls are organic gems with relatively low hardness. Avoid contact with perfume, strong acids, chemicals, harsh cleaners and excessive dryness. After wearing, wipe gently with a soft cloth and store separately from harder gemstones.

Treatment Disclosure

Clear on what has, or has not, been done.

Some pearls may be treated by processes such as bleaching, dyeing or irradiation. When known or relevant, treatment information should be clearly disclosed on the product page.

For verification of natural or cultured status and treatments, we recommend professional gemmological testing or a laboratory certificate rather than home tests.

Imitation Pearls

How we help you buy with confidence.

Imitation pearls may be made from glass, plastic or shell-based materials. For customer confidence, Lucky Jewellery focuses on clear product descriptions, close-up photography and certificate information where applicable.

Part A · The Seven Quality Factors

Core pearl quality factors.

Size

Measured in millimetres. Larger pearls are rarer, but size alone does not determine quality.

Shape

Round, near-round, off-round, drop, button, baroque and semi-baroque. Round pearls are the least common in most varieties.

Colour

Colour is a combination of body colour and possible overtone and orient — see Part B.

Lustre

The sharpness and intensity of reflections on the pearl surface. Lustre is generally the most important quality factor.

Surface Quality

The visibility, quantity and position of surface characteristics. Fewer, less prominent characteristics generally rate higher.

Nacre Quality

Thickness and structure of the nacre. Thin nacre may show a chalky look or reveal the bead beneath.

Matching

For multi-pearl jewellery: how consistently pearls match in size, shape, colour, overtone and lustre.

Part B · Colour Characteristics

Body colour, overtone and orient.

Body Colour

The dominant colour of the pearl — for example white, cream, pink, golden, silver, grey or black.

Overtone

A secondary translucent colour that can appear over the body colour, such as rosé, silver or green. Not every pearl shows a discernible overtone.

Orient

An iridescent play of colour that may appear on some pearls, most often on baroque shapes. It is a possible feature, not a guaranteed one.

We describe overtone and orient only when they are visibly present on the specific pearl.

Part C · Product Disclosure

What we always tell you about a pearl.

  • Natural or cultured status
  • Freshwater or saltwater
  • Pearl type (for example Akoya, South Sea, Tahitian, freshwater, Mabé)
  • Treatment disclosure
  • Declared cultivation region or stated origin, only where documented
  • Certificate information, where a certificate exists

Treatment disclosure is a mandatory disclosure item, not one of the seven pearl quality factors.

Origin & Cultivation Region

Origin is documented, not inferred.

We only display a cultivation region or origin when it is supported by supplier, farm or laboratory documentation. We never infer origin from pearl type, colour, size, product name, seller description or appearance. In particular, an Akoya pearl is not automatically described as Japanese.

Cultivation Time

Cultivation time is only stated when it can be supported.

Where cultivation time is recorded, we note its source and whether it is verified. A longer cultivation period does not automatically guarantee a better pearl — quality depends on the pearl itself, evaluated through the factors above.

Edison Pearls

A commercial category, not a species or origin.

Edison pearls are generally large bead-nucleated freshwater cultured pearls, known in the market for their size and varied colours.

“Edison” is a trade description. It is not a mollusc species, a geographic origin, a laboratory grade, or a guarantee of quality.

Mabé Pearls

Assembled cultured blister pearls.

Mabé pearls are generally assembled cultured blister pearls. A pearl dome is cultured against the inner shell and later completed with a backing to create a finished jewellery component.

A Mabé is disclosed as an assembled product; backing and filling materials are noted where known. It is not a solid, free-growing round pearl.

Conch Pearls

A rare non-nacreous organic gem — educational only.

Conch pearls are rare non-nacreous organic gems that may display pink colour and flame-like structures. They are not currently offered for sale by Lucky Jewellery. Any conch pearl would first require species identification, laboratory documentation, legal ownership, provenance, a CITES status review, import and export documentation where required, and country-specific sales eligibility.

Regulated Organic Materials

We do not sell restricted wildlife-derived materials.

Ivory, coral, tortoiseshell, giant clam materials, restricted shells and other wildlife-derived organic gem materials are not offered as public product categories. Where they are referenced in educational content, this does not imply that Lucky Jewellery sells them.

Pearl Certificates

What a certificate can, and cannot, tell you.

A pearl certificate may record the laboratory, report number and date, natural or cultured determination, freshwater or saltwater determination, pearl type where reported, treatment comments, colour comments, and measurements.

An uploaded certificate image is not, by itself, an independent verification. Our internal verification status simply records what has been checked in-house.
