Few things in a jewellery box carry as much quiet history as a strand of pearls. They've been worn by queens and film stars, passed from mothers to daughters, and reinvented by every generation that swore it wouldn't wear them — and then did.

But "pearl" can mean very different things depending on where you're shopping. Understanding the difference between freshwater pearls and faux pearls — and how to care for whichever you own — is the kind of knowledge that pays you back for decades.

What Is a Freshwater Pearl?

A freshwater pearl is a real pearl, grown inside a living mussel in lakes, rivers, and ponds — most of the world's supply is cultivated in freshwater farms. The mussel coats an irritant in layer upon layer of nacre, the same luminous substance that lines its shell, over months and years.

That nacre is what gives a real pearl its signature glow — a soft light that seems to come from within rather than bounce off the surface. Because each pearl is grown, not made, no two are identical. Slight variations in shape, size, and tone aren't flaws; they're the signature of a living process, and part of what makes a genuine strand feel alive against the skin.

What Is a Faux Pearl?

A faux pearl — sometimes called a simulated or imitation pearl — is manufactured, usually a glass, ceramic, or plastic bead coated with an iridescent finish. There is no shame in a beautiful faux pearl; some of the most iconic costume jewellery of the twentieth century was built on them, and they let designers play at scales and prices real pearls can't reach.

The differences show up in three places: the light, the touch, and the years. Faux pearls shine on the surface rather than glow from within, they're perfectly uniform in a way nature never is, and their coating — however good — can wear with time, where nacre endures for generations when cared for.

How to Tell Them Apart

A few gentle tests you can do at home:

The tooth test. Run a pearl lightly across the edge of your front teeth. A real pearl feels ever so slightly gritty — that's the layered nacre. A faux pearl feels glassy-smooth.

The warmth test. Real pearls feel cool the moment they touch your skin, then warm to you. Faux pearls tend to start at room temperature.

The twin test. Look down a strand. If every pearl is flawlessly identical in shape and colour, they're almost certainly imitation. Real freshwater pearls are a family, not a factory run — closely matched, never cloned.

The weight. Real pearls have a satisfying density. Plastic-based faux pearls often feel suspiciously light.

Why We Use Genuine Freshwater Pearls

At Valentine Rouge, the pearl pieces in our collections — like the White Pearl Innuendo and the Le Monde short pearl necklace — are strung with genuine freshwater pearls, chosen and handcrafted in our Toronto studio. We love them for the reason women have always loved them: they flatter every skin tone, they suit a silk blouse and a Sunday sweater equally, and they get more personal the longer you wear them.

Caring for Real Pearls

Pearls are organic — they were grown, and they like to be treated that way.

Last on, first off. Put your pearls on after perfume, hairspray, and lotion have settled, and take them off before you remove anything else. Cosmetics are the great enemy of nacre.

Wipe them after wearing. A soft, slightly damp cloth after each wear removes skin oils and residue. This one habit does more than everything else combined.

Store them gently. Keep pearls in a soft pouch or cloth-lined box, away from harder jewellery that can scratch them. Never in a sealed plastic bag — pearls like a little air.

Wear them. Truly. Pearls kept in a drawer for years can dull; pearls worn often stay luminous. They were made to be against skin.

Caring for Faux Pearls

Imitation pearls ask for similar courtesies for a different reason: their beauty lives in a surface coating. Keep them away from perfume and water, wipe them dry and clean after wearing, and store them so nothing rubs against the finish. Never soak or scrub them — once the coating lifts, it doesn't return.

The Heart of It

Whether your pearls were grown in a lake or made by clever hands, they deserve the same thing: to be worn often and cared for a little. But if you're choosing a strand meant to last — one your daughter might quietly covet someday — genuine freshwater pearls are the ones that keep their glow.

You'll find our pearl pieces among the necklaces, each one strung by hand in Toronto.
