Ring Sizing Tips:
The the most accurate way to determine your ring size is to be professionally measured by a jeweler. However, there are also several at-home sizing tools and tips to help find your ring size.
The most common rings sizes for women are size 6, 6.5 and 7.
For men, the most common sizes are 10, 10.5 and 11.
The most common kids ring size is 4 (ages 7-10) and size 5 for teens.
Usually, a finger on a dominant hand is a half to a whole size large than the same finger on the non-dominant hand. For example: If right-handed person wears a size 7 on their right ring finger, it is quite common for them to wear a 6 or 6.5 on left hand ring finger.

Chains

Spring ring clasps are a lightweight type of closure and great for keeping both weight and cost down (on solid gold chains especially). Most people find that lobster claw closures are much easier to close but with it may come a higher price tag.
The most common casual chain style for pendants is a cable chain.
Box and snake chains both provide a more smooth surface area to shine giving off a fancier, more evening-like look.
Rope and Spiga (wheat) chains are made with more links that are woven tighter together and are a great choice for heavier pendants.

Chain length may vary greatly depending on build & stature. The most common and average women's chain length is 16 to 20 inches long. The most common and average chain length for men is 20 to 24 inches long. Children tend to wear lengths from 14 to 16 inches long.
Chains under 1.00mm in thickness are great for petite pendants but may not hold up as well with larger pendants. We recommend chains that are at least 1.00mm to 1.30mm thick for pendants 0.75" to 1.5" in length. For pendants over 1.5" in length, a chain with over 1.30mm thickness is best.
