Ring Size Measuring Tips
Our dominant hands are generally slightly larger — make sure you measure the right finger on the correct hand.
Rings with wider bands will fit a bit tighter. If you plan to measure one of your partner's rings, try to measure one with a similar width as the ring you want to purchase.
Make sure the finger is at normal body temperature — fingers can shrink or expand when hot or cold.
Your fingers tend to change size throughout the day — the best time to measure your finger is the end of the day.
If your knuckle is bigger, take 2 measurements and choose a size in between — ring needs to fit over knuckle but not be too loose or it will shift around.
When you don’t know your partner’s ring size, selecting one of the standard ring sizes is your best choice. The average ring size for women is 6 to 9, and the average ring size for men is 9 to 13.

The earrings are very cute! They look a bit less colorful when in the case, but that's due to the lack of light hitting them. When they're on your ears they'll radiate the color they're supposed to.
These have become my daily wears!

Beautiful and perfect! Came in quick! I did end up getting the wrong size but that’s on me. They came in a ring box together and even some care instructions. Thank you for our very first set! We love them and hope they last a good while.

Shines like the stars!
My boyfriend and I went to flagstaff to the Lowell Observatory. Our thing is star gazing, and when I got back I wanted something that reminded me of our time. I happened upon an ad for this ring and I instantly had to buy it. I love it so much. The center stone is like a deep deep purplish blue and the sparkly stars inside it really do shine like the pictures. Its incredible. I am patiently waiting for him to buy the white gold version to get engaged with!
