Breastmilk jewellery holds something rather extraordinary. A part of your motherhood story, preserved in a piece of jewellery you can keep close long after those feeding days have passed.
But how does something as delicate as breastmilk become a lasting piece of jewellery?
At KARREK, every piece begins with your milk, a little science, and the understanding that what arrives in the post is so much more than a material to work with. It's a part of your story, and it deserves to be treated with care.
Every piece begins with your milk
Once you place an order through the KARREK website, I'll send out one of our milk collection kits containing everything you need to return your milk safely. If you've ordered a ring, your kit will also include a ring sizer so we can make sure your piece is the right fit.
You can send fresh or previously frozen breastmilk and if you have less than 5 ml just get in touch - I’ll let you know what’s possible. Once your milk arrives back with me, the making process begins.
Every little parcel of milk is different, and each carries its own meaning. I know that for some mothers, this milk can't simply be collected again. That's why careful handling sits at the heart of everything I do.
From breastmilk to milkstone
The first step is preserving your milk. This is a slow process, and one that can't be rushed. Your milk needs time to dry completely before it can be gently ground into a fine powder.
Over the years, I've carefully adapted and refined this process to get the very best from your milk. It's something I've spent a lot of time working on, because I know just how precious the little parcels arriving through my letterbox really are.
While your milk is drying, I'll also begin preparing your chosen jewellery setting. So, by the time your milk is ready, everything else is taking shape too.
The science behind the keepsake
Before KARREK, I studied geology and worked in geological laboratories, preparing rock and mineral samples for analysis in both private-sector and university settings.
My work involved handling delicate specimens and tiny, irreplaceable samples, where precision and careful preparation mattered.
That experience still shapes the way I work today.
Although breastmilk jewellery is a different kind of craft, the principle of treating each sample with care remains the same. Your milk is not something I can casually replace if something goes wrong. It is entrusted to me, and I take that responsibility seriously.
For me, this is where science meets sentiment: a considered process, thoughtful craftsmanship, and something deeply personal at the end of it all.
Bringing your milkstone into a piece of jewellery
Once completely dry, your milk powder is combined with our rigorously tested, jewellery-grade resin to create your milkstone. This creates a durable material that can be shaped and carefully incorporated into your chosen jewellery design.
The mixture is worked directly into your chosen jewellery setting, where it cures and is secured in place.
It's a process I've spent years refining, with every little detail considered along the way. Your milk is precious, and it's so important to me that every piece leaving my workbench is something you can treasure for years to come.
KARREK's designs are inspired by the natural shapes, landscapes and folklore of Cornwall. From quiet pools and smooth stones to the moon that keeps watch through long nights, these little details find their way into pieces made to hold a much bigger story.
A final polish, a little careful packing, and your jewellery is ready to make its way back home to you.
A keepsake of your motherhood story
Breastfeeding can hold so many things at once: closeness, exhaustion, comfort, uncertainty, pride and love. For some, it's a season they wish they could hold onto. For others, it carries a more complicated story.
However your journey looked, your milk is part of it.
My hope is that a KARREK piece gives you something small to reach for when you want to remember. Not a perfect version of motherhood, but your version of it, just as it was.
Every piece is made with your story at the heart of it.

Mamm is an all-time favourite in the collection — a ring made for the woman at the heart of it all.
Beautiful almond-shaped stones gather around the band, their soft, organic forms echoing the shapes found across Cornwall — smooth stones worn by the sea, rounded rocks scattered along the shore, and the gentle curves of the landscape. A shape that feels familiar, natural and quietly rooted in home.
Mamm is the Cornish word for mum. A small word that carries a lifetime of meaning — little hands reaching for yours, muddy feet on the path home, stories told as you walk, and all the simple rituals of family life.
Previously known as the Milk Ring, Mamm is a keepsake for the heart of the family — made to hold something precious, close.
