Size guide

Ring sizes here are US sizes. If you are between two, take the larger one — a ring has to pass the knuckle.

1 · Measure with a strip of paper or string

Wrap it around the base of the finger, snug but not tight.
Mark where it overlaps and lay it flat against a ruler.
That length in millimetres is your circumference — find it in the table.

2 · Or measure a ring that already fits

Measure straight across the inside of the band, edge to edge.
That is the inside diameter — the middle column below.

US size	Inside ø	Circumference
5	15.7 mm	49.3 mm
6	16.5 mm	51.9 mm
7	17.3 mm	54.4 mm
8	18.1 mm	57.0 mm
9	18.9 mm	59.5 mm
10	19.8 mm	62.1 mm
11	20.6 mm	64.6 mm
12	21.4 mm	67.2 mm
13	22.2 mm	69.7 mm
14	23.0 mm	72.3 mm
15	23.8 mm	74.8 mm
16	24.6 mm	77.4 mm

3 · Or check it against your screen

A screen has to be told how big it is first, or the circles below mean nothing. Hold any bank card against the outline and drag until they match.

85.6 mm — any bank card

Bracelets and chains are listed by their inner circumference — the size of the loop itself, not your wrist.

Measure your wrist

Wrap a strip of paper or string around your wrist, below the wrist bone.
Mark the overlap, lay it flat on a ruler and read the centimetres.
Add the allowance below for the fit you want.

Fit	Add	An 18 cm wrist
Close	+ 1.0 cm	18 → 19 cm
Comfort	+ 2.0 cm	18 → 20 cm
Loose	+ 3.0 cm	18 → 21 cm

A heavy link or a cuff wears shorter than a fine chain — if you are between two, the larger one is the safer pick.

Not right when it arrives? Every piece carries our Perfect Fit Guarantee — a free resize on any ring — and a 60-day money-back guarantee.

Thirty years behind this counter

For over thirty years the two of us shared one passion — fine jewellery made by hand. Every piece in the case started at our bench, for someone we hoped would wear it for the rest of their life.

Now it is time to hang up the loupe. We are closing our little shop to spend our days with our children and grandchildren, and to take the first holiday we have promised each other for years.

Margaret H.

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.

Verified Buyer

Barbara J.

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.

Verified Buyer

Denise C.

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

Verified Buyer

Susan D.

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

Verified Buyer

Anne & Robert T.

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

Verified Buyer

Patricia L.

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.

We would rather see them worn than boxed away

When a shop like ours closes, whatever is left gets packed into boxes and sold by the ounce. We could not do that to work we set by hand.

So the last of them are going to the people who supported us — free. You cover the shipping, once, and nothing else. When it is gone, it is gone: there is no shop left to order more.
