If you have been wondering what a mother of pearl necklace means, this guide gives you a straight answer and the evidence behind it. It is written by Awareness Avenue, and we sell the mother of pearl necklaces described further down, so we have kept our own views clearly labeled as ours.

It covers four things in order: what mother of pearl is, one documented piece of history, how to think about meaning when you choose a piece, and exactly what each necklace in this guide is made of. A short note on care and a set of common questions close it out.

What a mother of pearl necklace means, in short

In our view, a mother of pearl necklace does not come with one fixed meaning built into the material. What it says depends mostly on two things you control: the shape of the piece and the reason it was chosen. A heart given to mark a relationship says something different from a carved flower bought as a present to yourself, even when both are made from the same material.

That is our framing, not a rule we can prove for every piece.

What mother of pearl is

Paspaley, an Australian pearling company, explains in its guide to what mother of pearl is that mother of pearl, also called nacre, is the material pearl oysters use to line the inside of their shells: aragonite held together with organic proteins, laid down in a great many flat layers.

A pearl forms differently: it grows inside the oyster’s soft tissue, with nacre building up in rings around a nucleus, while mother of pearl is laid flat over the shell. So a mother of pearl pendant is made from nacre, not from a pearl.

Paspaley also notes that the broader word “shell” can include material with no nacre, while mother of pearl means the nacre itself. Its color shifts as the light changes, and individual shells vary.

Those facts describe the material. Meaning is a separate question, and the next two sections deal with it.

A documented history

The Foundling Museum’s page on love tokens, written by historian Dr. Sally Holloway of Oxford Brookes University, looks at the objects left with infants at the Foundling Hospital.

She writes that some of those infants were left pendants shaped like hearts and made of mother of pearl, which she calls “a common material for jewellery during this period.” The page also shows a token captioned as a mother of pearl heart, object number 2005.5.389. Holloway calls the heart the period’s strongest symbol of love of any kind, and reads the tokens mothers left as expressing their love and grief, their desperation, and what they hoped for their children.

Our own reading of this history is that the meaning sits with the heart shape and with the person who left the token, not in the material itself. This is one practice from one collection, not a rule for every mother of pearl necklace.

Choosing the meaning: shape, giver and occasion

What follows is our view as a jewelry brand, not a historical rule or a claim about tradition.

Start with the shape

A heart is the most direct choice if love is the message you want to send. For the other shapes in this guide, a butterfly, a carved flower, an oval, a curved accent and a set of gourd motifs, we would rather not hand you a stock meaning. If one of those shapes already means something to you or to the person you are buying for, because of a nickname, a garden, a place or a shared joke, that private meaning is worth more than anything we could print on a card.

Let the giver set the message

A pendant cannot explain why it was given. If you are buying one as a gift, a short note saying why you chose that shape is, in our view, the part that carries the meaning. The necklace is what they wear; the note is what tells them why.

Choosing for yourself

If the necklace is for you, the same idea works in reverse. Pick the shape that marks whatever you are marking, a decision, a new role, the end of a hard stretch, and let that be its meaning. No one else needs to know what it stands for.

Fit it to the occasion

A heart suits an anniversary or a relationship milestone. A carved flower or a plain oval can work as a birthday present or as a gift to yourself. None of these pairings is a rule; they are a way to make the choice deliberate rather than generic.

Read the material line first

Before you settle on a piece, check the material named on its listing and in the variant you select. In this guide that ranges from stainless steel with a gold-tone PVD finish to 18K gold vermeil over sterling silver to solid gold, and the listing is where it is stated.

This guide makes no healing, calming or protective claims for mother of pearl or for the necklaces in it. If a belief like that matters to you, it is yours to hold; it just isn’t something we can promise.

Our mother of pearl necklaces, described exactly

Each description below comes from the product’s current listing. Where a listing calls the mother of pearl natural, we say it is listed as natural. Seven of the nine listings here are stainless steel with a gold-tone PVD finish; the other two are the Farfalla listings described first. If you are still weighing pendant styles in general, our guide to necklace styles and meanings covers the wider picture.

The Farfalla Mother of Pearl Necklace

The Farfalla design appears in two listings. The Farfalla Mother of Pearl Necklace is a butterfly pendant with a mother of pearl inlay, listed at 10mm, on an O-chain listed at 15.7 inches with a 1.6-inch extender, adjustable to 17.3 inches. The listing describes it as 18K gold vermeil over sterling silver, and its material options include sterling silver and 18K rose gold vermeil. The same listing also offers 14K and 18K solid white gold and solid rose gold options. Its listing also says that gold orders include an automatic upgrade to VVS moissanite center and accent stones, so check the listing for exactly what a gold option includes.

The Farfalla in solid gold

For solid gold, the design has a dedicated solid gold listing. It offers the butterfly pendant with a mother of pearl inlay in 14K or 18K solid gold, in yellow, white or rose gold, with the same 10mm pendant and an O-chain adjustable from 15.7 to 17.3 inches.

The Carved Floral Station Necklace

The Carved Floral Station Necklace has a carved mother of pearl floral pendant on a beaded station chain. Its listing describes the focal piece as carved natural mother of pearl shell. Stainless steel with a gold-tone PVD finish; 16, 18 or 20 inch.

The Audrey Mother of Pearl Necklace

The Audrey has an oval, bezel-set pendant listed as natural mother of pearl, on a beaded satellite chain. Stainless steel with a gold-tone PVD finish; 18 inch chain, which the listing says adjusts with a 2-inch extender. A plain oval is a good choice if you want the material to read clearly without a motif attached.

The Elysian Molten Oval Necklace

The Elysian sets a cabochon listed as natural mother of pearl in an organic, molten-look gold-tone bezel. Its chain is asymmetric, with a paperclip chain on one side and a beaded cable chain on the other. Stainless steel with a gold-tone PVD finish; 18 inch.

The Rosetta Mother of Pearl Necklace

The Rosetta holds a heart listed as natural mother of pearl inside a textured circle frame. Stainless steel with a gold-tone PVD finish; 16, 18 or 20 inch. It is the only piece in this guide listed as a heart. For what different heart designs can say, see our guide to choosing meaningful heart jewelry.

The Dianella Mother of Pearl Necklace

The Dianella has a curved accent inlaid with mother of pearl, listed as natural, on a flat snake chain. Stainless steel with a gold-tone PVD finish; 16 to 18 inches adjustable.

The Brielle Mother of Pearl Necklace

The Brielle is a butterfly with a natural mother of pearl inlay and cubic zirconia accent wings, per its listing. The pendant is listed at 20mm by 15mm, on a 16 to 18 inch adjustable chain. Stainless steel with a gold-tone PVD finish.

The Gourd Station Necklace

The Gourd Station Necklace has five gourd motifs inlaid with mother of pearl, listed as natural, on an 18 inch chain. Stainless steel with a gold-tone PVD finish. As with the other shapes, we leave the meaning of the gourd to you.

Caring for mother of pearl

Paspaley says mother of pearl is suitable for regular wear when it is looked after, and advises avoiding long contact with strong chemicals and knocks against hard surfaces.
