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.

These earrings are beautiful. They are eye catching. I love them.

A Dreamy Pink Morganite Ring

I absolutely love my ring! The fantasy cut morganite sparkles beautifully and the soft pink color is even more stunning in person. The leaf band design is so delicate and unique, and the whole piece feels very special. Shipping was quick and everything arrived perfectly.
It came with a really pretty, soft purple box (53mm × 61mm), which was such a lovely surprise. The stone is about 1.2 ct. (8×6mm) and I'm size 5 US.
Thank you so much, Aquamarise, this piece truly feels like a little work of art, and I couldn’t be happier with it.

We’re overjoyed to hear that you love your ring and find it to be a little work of art! It’s great to know that the design and packaging added to your experience. Thank you for your wonderful feedback!

Totally in love with them! 🥰

This couple ring set is absolutely stunning! The deep purple tones and unique fantasy-inspired design make them stand out from ordinary rings. What I love most is how eye-catching and different they are—perfect for anyone who wants something stylish, meaningful, and a little magical. 💜✨

Absolutely in love

My husband proposed to me with this gorgeous ring in silver, and I got both bands when we said, "I do". Not only is it perfect because the ring and I share the same name, but it also keeps up with day-to-day activities and is really durable. My rings are always shiny, and I get so many compliments on them! I highly recommend this set for a refreshing take on a classic look. The color changes of the Alexandrite are gorgeous and never fail to take my breath away. Truly a unique set. Love it to pieces, pictures don't do it justice.

We’re overjoyed to hear that you love your ring and that it holds such special meaning for you! It’s wonderful that it’s both beautiful and durable for your daily activities. Thank you for your heartfelt recommendation! ✨
