Each jacket is individually cast, hand-finished, and stone-set. We don't keep inventory because every piece is made for you.
Product Details
Two stones, one story. The Alexander is a toi et moi smart ring jacket featuring a pear-cut stone in the lead position with an emerald-cut stone set just behind it, each bezel-set in polished sterling silver. Choose your stones from 12 stunning options for each shape, mix and match birthstones, favorite colors, or stones that simply speak to you. The result is a combination that is entirely, unmistakably yours.
The Alexander is designed to fit the Oura Ring Gen 5 and RingConn 2 and 3, sliding seamlessly into place without interrupting a single health metric.

Order the same size as your smart ring. If you wear a size 8 Oura, order a size 8 jacket. We craft each piece to fit that exact size — no universal sizing, no guesswork.
Every jacket is tested on a real smart ring before it ships. If there's a fit issue, reach out within 30 days and we'll make it right.
Production time: 2–3 weeks. Every jacket is made to order — casting, finishing, stone-setting, and quality control each take time. We don't rush it.
Shipping: Currently shipping throughout the United States. Your jacket arrives in an unmarked box with custom packaging inside, polished and ready to wear.
Returns: Because each piece is custom-made to your size, stone, and metal selection, all sales are final. If you need a size adjustment, contact us and we'll work with you. If your jacket arrives damaged, email support@smartringjackets.com with photos and we'll replace or repair it.
New to ring jackets?
It slides on in seconds. Your ring does the rest.
A smart ring jacket wraps around your existing ring from underneath — two precious-metal bands frame it, and a hand-set stone sits on top. Your ring stays in the center, fully visible and fully functional. Think of it as a styled setting for the tech you already wear.
Made by hand, by us
Every jacket that ships was made in our garage in Minot, North Dakota.
We're Brooke and Shane — the only two hands that touch your ring from casting to shipping. No factory, no overseas production, no middleman. Just a husband-and-wife team who care about getting it right.

It feels less like a bland health tracker on my finger and more like a beautiful accessory that matches my aesthetic. The craftsmanship is incredible — you can tell each piece is made with real care. I couldn't be happier with how it elevated both the look and experience of wearing my Oura ring.
I used to take my Oura off for date nights and weddings. Not anymore. The jacket completely transforms the look — people don't even realize it's a smart ring underneath. The moissanite catches light beautifully. Worth every penny.
The fit is perfect — no movement at all. Slides on and off easily when I want to switch styles. I already ordered a second one in pink sapphire. The 2-week wait is worth it for this level of quality.
I was skeptical about how the charging and tracking sensors would handle a metal frame wrapping over it, but it works flawlessly. Zero data drops on my health app and it turns heads everywhere I go. Simply brilliant fine jewelry engineering.
