Find Your Ring Size
Finding Your Ring Size.
- Cut a strip of paper or a piece of string. Wrap the paper or string around the finger to be sized.
- Slide the paper or string up to the knuckle, as the ring must be sized large enough to able to slip off and on, over the knuckle.
- Mark the intersection point of string. Make sure to mark both points of the string.
- Place the paper or string next to a ruler and write down your measurement.
- Locate your ring size by locating your measurement on the size chart.
If the measurement falls in between two sizes, it is recommended that you choose the larger size. Your fingers might also swell if you're pregnant or taking certain medications. Take this into account when measuring your fingers
Finding the Ring Size for Your Loved Ones.
- Find a ring that your loved one currently wears.
- Make sure he or she wears that ring on the finger you are shopping for.
- Using a ruler to measure the inside diameter or inside circumference of the ring.
- Match your measurement with our size chart to find your perfect fitting size!
If the measurement falls in between two sizes, it is recommended that you choose the larger size.

I bought a best friend bracelet for her bday...
"I bought a best friend bracelet for her bday and she loved it. It is great workmanship, delivered on time and my whole experience has been a positive one. Usually, I am skeptical of ordering because it's never like you see in the picture but this exceeded my expectation and I look forward to buying other jewelry from them."
