Our Story

Why We're Closing Our Doors

For over thirty years, William and Kimberly shared one passion — creating fine jewellery by hand. Rings, necklaces, earrings and bracelets in solid gold and sterling silver, each piece set with genuine gemstones and finished at our bench, one at a time.

After all these years, we've decided it's time to close our doors for good.

Now it's time to hang up our loupe. We're closing our little shop to finally spend our days with our children and grandchildren — and to take the first holiday we've promised each other for years. Rather than box up the beautiful pieces we have left, we'd far rather see them worn and loved. So until the very last one is gone, every piece is free — you only cover the shipping.

It's a genuine farewell, with real, limited stock. Once it's gone, it's gone. Thank you to everyone who has worn a William & Kimberly piece over these years. — William & Kimberly

A note from the workshop

⚠️ Beware of Cheap Imitations

Now that we're giving these pieces away, copycats have started passing off cheap, hollow look-alikes as the real thing — thin plated pieces that bend, discolour and turn your skin green within weeks.

Every genuine William & Kimberly piece is crafted in solid sterling silver or 18K gold, set with genuine gemstones by hand, and backed by our lifetime warranty. If it wasn't bought here, we can't promise it's the real thing — or that it'll last a lifetime the way ours do.

See what our happy customers have said over the years.

My husband surprised me with the pendant for our 40th anniversary — I actually teared up when I opened the box. It hasn't left my neck since.

Margaret H.

I've worn this ruby ring every day for a month and it still catches the light the way it did the first morning. Real weight, real gold.

Barbara J.

Bought the sapphire earrings for my daughter's wedding and ended up wearing them myself. Elegant without being fussy.

Denise C.

The bracelet arrived beautifully boxed with a handwritten note. You can tell this shop was built with love over a lifetime.

Susan D.

We ordered together — a necklace for her, a keepsake for me. So glad we found William & Kimberly before they closed their doors.

Anne & Robert T.

At my age I don't buy much jewellery any more, but this one felt special. Real gold, a real stone, and it arrived quickly.
