Body-Safe Verified

Body-safe by design — not by claim.

The Diamo is made from silicone that Lovense describes as body-safe, and Lovense states its products contain no phthalates. It is rated IPX7 waterproof. Lovense advises wearing a cock ring for no more than 30 minutes at a time, removing it right away if you feel pain or your genitals feel cold, and checking with a doctor first if you have a blood-clotting, vascular or nerve condition or take blood thinners.

Common questions

Straight answers to the questions people ask before buying.

Usage
Will the Diamo fit me?
The inner opening is about 1.75 inches, and Amazon's listing says it stretches to a perimeter of about 16.5 cm. Reviewers found it snug: it works well for average girths, but if you're on the larger side it may be too tight. Put it on before you're aroused.
Usage
How long can I wear it?
Lovense says a cock ring shouldn't be worn for more than 30 minutes at a time. Take it off right away if you feel pain or your genitals feel cold.
Body-Safe
Who should check with a doctor first?
Lovense advises checking with your doctor before using any cock ring if you have erectile dysfunction, a blood-clotting disorder, a peripheral vascular or nerve condition, or you take blood-thinning medication.
Usage
How do I put it on?
Before you're aroused, apply a little water-based lube, put one testicle through at a time, then carefully slip the penis through the ring. Point the tail toward your perineum or toward your partner.
General
Is it loud?
Reviewers measured about 46 dB at its loudest — quiet enough to be covered by normal background noise. You can also lower its maximum vibration in the app.
Battery
How long does the battery last?
Lovense says 2.5 to 3 hours of continuous use, after about 70 minutes of charging on the magnetic cable. If the red charging light doesn't come on, rotate the cable 180 degrees.
Warranty
What's the warranty?
Lovense covers it for one year from purchase against defects. As with all intimate products, it can't be returned for change of mind. But if it arrives damaged, faulty or incomplete, tell us within 14 days and you choose a replacement or a full refund. After 14 days, we handle the Lovense warranty claim for you.

How to use, clean, and store

The full guide, step by step.

  1. 1. Charge fully before first use — about 70 minutes on the magnetic cable.
  2. 2. Wash it with warm water and mild soap, then dry.
  3. 3. Hold the button for 3 to 5 seconds; it vibrates once when it turns on.
  4. 4. Apply water-based lube to the ring and yourself.
  5. 5. Put it on before you're aroused: one testicle at a time, then slip the penis through.
  6. 6. Position the tail toward your perineum or toward your partner.
  7. 7. Wear it for no more than 30 minutes at a time.
  8. 8. Remove it right away if you feel pain or your genitals feel cold.
Important: Don't wear it for more than 30 minutes at a time. Use water-based lube only, never boil it, and don't use it while charging.
  1. 1. Turn the toy off first.
  2. 2. Wash with warm water and mild soap or a sex toy cleaner before and after each use.
  3. 3. It's IPX7 waterproof, so rinse it fully under the tap.
  4. 4. Clean inside the ring, where lube collects.
  5. 5. Never boil it.
  6. 6. Dry thoroughly before storing.
  1. 1. Make sure it's completely dry.
  2. 2. Store it in a clean bag — black silicone shows dust and lint.
  3. 3. Keep it away from extreme heat or cold.
  4. 4. Keep it apart from other silicone toys.
  1. Charge it fully first — about 70 minutes
  2. Put it on before you're aroused
  3. One testicle at a time, then the penis
  4. Set a 30-minute limit for each session
  5. Try the tail facing you, then your partner

The Lovense Diamo App-Controlled Vibrating Cock Ring story

Why we carry it.

Most vibrating cock rings are made for one moment: partnered sex, with a little buzz aimed at your partner. Lovense designed the Diamo to be more flexible than that. It's a smooth silicone ring with a vibrating tail, and you can wear it with the tail pointed down toward your own perineum or up toward a partner. Some reviewers also use it on its own as a solo toy.

Vibrating ring with a tail you can point at your perineum or your partner, app-controlled

It's an app-connected toy first. The button on the ring handles power and basic levels, and the Lovense Remote app adds custom patterns, music sync, and long-distance control so a partner can run it from across the room or across the country. The vibration comes from a single motor in the tail, and the ring carries some of it too.

The practical specs are simple. Lovense says the Diamo is made from body-safe silicone and its products contain no phthalates. It's rated IPX7 waterproof, charges on a magnetic cable in about 70 minutes, and runs 2.5 to 3 hours. Two reviewers measured it at about 46 dB at its loudest — quiet enough that background noise covers it.

Fit is the one thing to think about before you buy. The ring is about 5.24 inches long overall, with an inner opening of about 1.75 inches. Amazon's listing says it stretches to a perimeter of about 16.5 cm. Obsession Rouge and Bedbible both found it snug, and Bedbible's tester found it hard to put on. Obsession Rouge's view was that it works well for average girths but larger girths should be careful. Lovense's own guidance is to put it on before you're aroused, one testicle at a time, wear it for no more than 30 minutes, and take it off right away if anything hurts or feels cold.

We stock the Diamo because it's one of the few app-connected rings that works for solo play as well as with a partner, and it pairs naturally with Lovense's other toys for him. It ships discreetly in plain packaging. As with all intimate products, it can't be returned for change of mind. But if it arrives damaged, faulty or incomplete, tell us within 14 days and you choose a replacement or a full refund.

Pleasure With Purpose

Every purchase helps women impacted by sexual exploitation.

Pleasure With Purpose is our promise that pleasure should never come at anyone's expense. Launched in 2026 — our very first year in business — it directs 5% of every purchase to Canadian charities that support women impacted by sexual exploitation. We chose to start on day one, rather than "once we could afford it," because a brand built on consensual pleasure owes something to the women the wider industry has harmed. Every year we'll publish the numbers, the recipients, and the receipts.
