Ring Size Guide

A ring should feel secure but slip comfortably over your knuckle. The easiest way to find your size is with a ring you already love wearing.

Option 1 · Measure a ring

  1. Choose a ring that fits the finger you plan to wear your new Larimar ring on.
  2. Place the ring on a ruler and measure straight across the inside edges in millimeters.
  3. Find that inside diameter in the Size chart tab.

Option 2 · Measure your finger

  1. Wrap a thin paper strip around the finger where you will wear the ring. It should be snug, not tight.
  2. Mark where the paper overlaps. Check that the marked loop can pass over your knuckle.
  3. Lay it flat and measure from the edge to your mark in millimeters.
  4. Find the closest circumference in the Size chart tab.

Tip: For best results, measure late in the day and repeat the measurement. Wider ring bands can feel tighter.

Find the US size in the table below using your ring's inside diameter or finger circumference.

I rarely give 1-2 star reviews yet I do believe this deserves that. This company covers their tracks in saying no two are the same yet what they don’t share is the quality I received was maybe an B/A and there were scratches on it. It looked nothing like the picture and was poorly made for the cost. I was going to return it but their return policies are for the company, not the customer. They even note you foot the bill both ways and they have to approve the return. I did provide feedback in email and didn’t ask for a refund or exchange. I just gave feedback. The CEO reached and noted the ideas weren’t feasible like transparent photos or being able to choose. When you’re buying high end items: You choose. I lived and learned and I’ll never be back.

Hi Anne,

We appreciate you sharing your thoughts, though we’re sorry to hear that your piece didn’t meet your expectations. Like all our jewelry, our Pink Conch Moon Charm is made from natural materials, and we are transparent about the fact that each stone is unique. While we do not use letter grading in our product descriptions, the piece you received meets the high-quality standards we uphold.

Regarding our return policy, we aim to be fair while maintaining the integrity of our handmade, one-of-a-kind pieces. We outline all policies clearly on our website, including that customers cover return shipping, which is standard for small businesses with limited inventory—especially for us, as we are based in the Dominican Republic and ship internationally. These policies help us continue offering high-quality, unique pieces while ensuring fair logistics for our customers and team. Every return request is carefully reviewed to ensure fairness on both sides.

Also, when a customer requests to see the pieces available before purchasing, we are always happy to share photos upon request, giving the customer the chance to choose. However, due to the number of pieces we carry, it is not feasible to display every individual variation on our website in advance. We do our best to represent the natural variations through our product listings while ensuring a smooth shopping experience.

We value feedback and always look for ways to enhance the shopping experience. That said, we regret that you were disappointed, and we hope you find a piece elsewhere that aligns with what you were looking for.

Wishing you all the best,

The Larimar Shop
