Ace Tennis Racket Ring
A little wink of match point.
As Seen On
The one people ask about.
- A tennis-racket motif strung in fine crystal mesh, on a pavé band.
- Reads as a wink on its own; reads as intent in a stack of three.
- Gold-tone over a stainless-steel core — waterproof, tarnish-resistant, hypoallergenic. Steel doesn't corrode, so there's nothing in there to react with your skin.
On through the sink, the shower and the actual court. You'll stop explaining it and start noticing who spots it.
Ace is not trying to be serious, so do not style it seriously. It belongs with jeans and a plain top, where it can be the one piece with a sense of humour.
Ace stacks cleanly. Sit it directly against another band rather than spacing the two out, and mix widths — a wider band beside a fine one always reads better than two of the same.
It is worn best with Lena Elephant Charm Bracelet and Florence Sport Charm Necklace, which are drawn in the same design language as Ace. Repetition across pieces is what makes a few things read as one look.
Free tracked shipping on orders over $125. Under that, a flat rate shown in your cart before you pay, never added at the last step. Orders leave within 2 business days and arrive in 5–10.
You have 30 days from your purchase date to request a return. The conditions are real and you should read them now rather than at the return form: return shipping is yours, a 25% restocking fee applies, one claim per customer, on a first-time full-price order. Sale-priced items are excluded; discount-code orders remain eligible.
There isn't any, and that's the point. Shower in it, swim in it, sweat in it, sleep in it. Chlorine, salt water and sanitizer are all fine.
The one honest limit: perfume, hairspray, body oil and nail polish remover dull any finish over time, ours included. Apply those first, jewelry second.
Size Guide
Two minutes and a piece of string. Then you never guess a size again.

- Fixed-size rings: US 6, 7 and 8 — the three sizes ordered most since 2023.
How to measure your ring size
-
Wrap and measure
Wrap a strip of paper or string snugly around the base of your finger. Mark where it overlaps, then measure the length in millimeters.
-
Match to the chart
Compare that measurement to the Circumference column above to find your US size. Between two sizes? Choose the larger one.
-
Or measure a ring you own
Measure the inside diameter of a ring that already fits well, then match it to the Diameter column above.
Size up. A slightly looser ring is more comfortable than one that's too tight, and a ring guard takes up any extra room.
Our adjustable, open-back rings flex across most hand sizes. If your size runs above a US 9 or below a US 6, take one of the fixed-size styles instead.
Yes — fingers run smaller in the morning and in cool weather, larger by evening or in heat. Measure a few times across a day and use the average.

Cheaper is only cheaper the first time.
Costume jewelry is priced to be replaced, and most people replace it two or three times a year without ever adding it up. This is the other option.

- Shower, pool and sea — keep it on
- Same colour on day 200
- Nothing in there to react with skin
- Bought once, not every season
- Replaced free if the colour goes
Ordinary jewelry
- Fades within weeks
- Leaves a green mark
- Comes off at the shower door
- Itches by hour ten
- Replaced every season
The best thing it does is nothing at all.
This isn't a statistic, it's the pattern. What you're buying isn't a piece of jewelry so much as one fewer decision every morning.
