Quality product

This ring surpassed my expectations. I have been looking for a replacement ring for my husband as the original band I bought him from another seller wore out significantly. This ring is quality made and fits fantastically!

My hubby loved it!

I took his original wedding band to get sized and ordered the same size. When he opened it for Christmas he was shocked at the quality of the ring. 🙌

Runs 0.5 Size Small

I called to custom order this ring at 7mm wide instead of 9mm. Dave was great and custom ordered the ring for me, no problem. I went to a jewelry store and tried on several rings to make sure I got my size right and I ordered size 8.5.

I really like the ring, but it is definitely about 0.5 size too small. I will have to re-order in a size 9 instead of 8.5.

Met expectations

My husband loves this ring. Perfect size. Excellent value.

Trinity ❤️Neo

Excellent!
⭐⭐⭐

Great ring

Looks amazing, super lightweight, love how it looks on my fiance's finger and it fits perfectly! Can't wait for our big day!

Excellent quality and even better service

My wedding was in 5 weeks and I wanted to make sure there was enough time with the 3 week time frame for orders. I spoke with David on December 12th and the ring was shipped 4 days later on the 16th. I couldn't be happier with the ring and the help that I received from David. The ring fits perfect and is very light.

My husband loves it!

Originally ordered the wider version but my husband thought it was too wide. Easy to do exchange. He is very happy with the narrow version. It is nice looking and crazy light.
