Based on the photos, this appears to be a Calmi Ring (sometimes marketed as "Calmi Ring – The Original").

What it is

The Calmi Ring is a stainless steel magnetic wellness ring that the company markets as combining:

• 🧲 Magnetotherapy (small magnets embedded inside the ring)

• 👆 Acupressure (pressure on points of the finger)

• 💍 Adjustable design that fits most finger sizes

The company advertises it as helping with:

• Stress and anxiety

• Better sleep

• Energy and well-being

• Circulation

• Pain relief

These are the manufacturer's marketing claims. (Calmi)

What I can tell from your photos

• Brand: Calmi

• Color: Gold

• Includes 2 adjustable rings in the presentation box.

• Comes with a Calmi Wellness insert card showing links to their app (Apple App Store and Google Play).

Important note

While the company markets these wellness benefits, there is currently no strong scientific evidence that magnetic rings or acupressure rings reliably reduce stress, improve sleep, or provide the other health benefits claimed. Many reported benefits may be subjective or vary from person to person. (Calmi)

If you're planning to sell it, you could describe it as:

If you're selling on eBay, I can also help you determine:

• whether it's authentic,

• its approximate resale value,

• and write a complete eBay listing with title, description, item specifics, and suggested price.
