Discover Your Ideal Fit with Fantasy’s Size Guide

Fantasy Diamonds Fine Diamond Jewelry

Whether you’re shopping for yourself or a loved one, Fantasy’s size guide is the answer to your sizing concerns. Our guide will direct you to the correct size, ensuring a flawless fit. Let’s find out how you measure up!

Necklace Sizing

We make Fantasy necklaces as short as 12.5” and as long as 26”. Most of our necklaces can be ordered at varying lengths, for an optimal fit. Chokers range from 12.5” – 15”, necklaces up to 15.5” inches generally sit right along the collarbone, and 16” and longer are more traditional necklace lengths.

Ring Sizing

Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance.

  • Wrap a string or paper around the base of your finger.
  • Mark the point where the ends meet with a pen.
  • Measure the string or paper with a ruler in millimeters.
  • Divide the measurement by 3.14 (or Pi) to get the diameter of the ring.

We offer bracelets as short as 6” and as long as 8.5”. We like a closer fit on our bracelets, but the choice is yours! A measuring tape wrapped loosely around your wrist should help approximate the size to choose.
