Size Guide

Ring Sizing

If your knuckle is wider than your finger, measure both and choose a size in between for a smooth, secure fit.

How to Measure

Measuring a Ring

  1. Select a ring that properly fits your desired finger
  2. Measure the internal diameter of the ring (in millimeters)
  3. Use the chart below to determine your ring size

Measuring Your Finger

  1. Tear up a strip of paper or cut a piece of string
  2. Measure the internal diameter of the ring (in millimeters)
  3. Use the chart below to determine your ring size

Measuring Tips

  • Measure at a comfortable body temperature. Heat causes swelling; cold can shrink fingers.
  • Avoid sizing after salty foods or drinks.
  • If you're between sizes, size up for the best fit.

The one that stops people mid-sentence. Mara is a full eternity band with marquise moissanite stones, each set at an angle. Wears alone. Stacks better.

Lab-grown moissanite. Real gemstone. Brilliant sparkle. Scratch-resistant. Won't cloud or dull. Moissanite is wildly misunderstood. It's the second hardest gemstone on earth and it looks incredible in any lighting. Moissanite is its own thing, it's not pretending to be something else.

Every piece is set in sterling silver or 18K gold vermeil. Made to order. Built to last.

Finally a brand that gets it! I've been searching high and low for something in between my solid gold pieces and Mostly Fine fills that need perfectly.

The wrap ring is stunning. I was afraid it would look cheap in person but it looks so expensive. I love how it looks on.

Made to wear now.

Every piece at Mostly Fine is built with one idea: jewelry you'll actually wear, not save. We chose moissanite, sterling silver and 18K vermeil because they're bright, durable, and beautiful — not because they're pretending to be something else.

The metalwork is precise. The stone setting is tight. The finish is intentional. This is jewelry made for you in this moment, not for your future granddaughter's archive.

Wear it today. Stack it tomorrow. That's all.

Also fine.
