Necklace Styling Guide

Most necklaces naturally fall just below the collarbone, usually somewhere between 18 and 20 inches, depending on your height and neck shape. Choose a length where your pendant sits comfortably and feels right for you. Beyond that, necklace length has no strict rules because it comes down to your style and how you love to wear it!

Here's a quick guide to help you choose:

14" – Sits high like a chic choker. Great for layering and creating a trendy stacked look.
15" – Just below a choker, offering a little breathing room. Perfect with crew necks or scoop neck tees.
16" – One of the most popular lengths, resting at the base of your neck. Super versatile and a must-have for any collection.
17" – Hangs just below the collarbone, elongating the neck and flattering almost any neckline. Ideal for intricate pendants or layering with shorter pieces.
18" – Classic medium length, perfect for showing off charms and pendants. Works with nearly everything!
19" – Falls at the top of your bust. Looks stunning with plunging necklines or layered for a bold, dimensional effect.
20" – Drifts just above the chest. Excellent for statement pendants, personalized charms or dramatic layered looks.

Measurement Guide

Option 1: Using a Measuring Tape

Start with your palm open and facing up.
Wrap a measuring tape around your wrist, just above the wrist bone.
Mark the point where the ends meet with a pen or marker.
Take a note of your wrist measurement, and refer to the chart above.

Option 2: Using String or Paper and a Ruler

Begin with your palm open and facing up.
Wrap a piece of string or a thin strip of paper around your wrist, just above the wrist bone.
Mark the spot where the ends meet.
Lay the string or paper flat and measure from the start to your mark to find your wrist size.
Note down the measurement and refer to the size chart above.

Pro Tip for Extra Comfort:

To ensure your bracelet isn't too tight, add about 0.5 inches (12 mm) to your wrist measurement. This gives you a perfect balance of style and comfort.

How to Choose the Right Ring Size

A perfect choice! Now comes the tricky part: making sure it fits just right. A perfectly fitting ring shouldn't slide off your finger too easily, but it should glide on smoothly without any struggle.

If you already know your ring size but need a little help converting it, you can use our handy ring size conversion chart. If you're still unsure about your size, the simplest solution is our ring size guide. Just download and print it, then grab a ring that fits comfortably on the same finger you plan to wear your new one on. Place your ring on the chart, and voilà, you've got your perfect size.

Measurement Guide

With a few simple steps, you can also get a precise measurement in minutes, all from the comfort of your home. Here's how:

Ring Length Guide - Visual representation of different ring lengths

Grab a thin strip of paper or string (no wider than ½" / 1.4 cm).

Wrap it snugly around the base of the finger you'll wear the ring on.

Mark the point where it overlaps to form a full circle.

Measure the length from the start to your mark with a ruler.
Check our ring size chart and pick the closest size for a perfect fit.

Pro Tip for Perfect Fit:

For the most accurate measurement, measure your finger at the end of the day when it's at its largest. Also, make sure your hands are at normal room temperature, as fingers can shrink in cold weather and expand in heat.
