Fiorella
Centered by an oval-cut Australian opal, Fiorella places a black diamond on either side for a sharp contrast between shifting color and deep, dark accents. The three-stone arrangement keeps the silhouette clean and balanced, while the unexpected combination gives the ring a moodier character than a traditional opal setting.

What Our Clients Say

5.00/5

Client photo of Secret Garden Ring in Emerald Cut Alexandrite - Jasmine

Absolutely blown away by this set! I ordered the Jasmine emerald-cut alexandrite ring along with the Chloe band, and pictures honestly don't do them justice. They look exceptionally well made. Shipping was surprisingly fast, and customer service was so helpful in getting my order expedited. 10/10 experience!

Client photo of Oval Floral Vintage Peach Sapphire Ring - Harmony

I’ve been eyeing this exact design for years, and my now-fiancé finally surprised me with it! The peach sapphire is absolute perfection! I’ve been wearing it every day and have gotten so many compliments from coworkers and friends.

Client photo of Botanical Marquise Cut Alexandrite Ring – Alyssa

I was a little nervous ordering an alexandrite online without seeing the color shift in person, but the team sent over a video showing the stone changing from green to red in different lights. That sold me! In person, the ring is even more stunning and super comfortable for everyday wear. I get compliments on it almost every single day!

I love how warm the yellow gold band looks against the diamond!

Client photo of Oval Cut Aquamarine Diamond Ring - Azure

I wanted to wait a few months before leaving a review—I've had my Azure ring for about three months now and I love it so much. The blue stone is gorgeous in natural light. It does catch a bit of oil/lotion over time, so giving it a quick gentle wash every few weeks keeps it looking brand new.

Client photo of Cat Engagement Ring - Misty

I spent so much time searching for a ring that subtly represented my cat and found this. I opted for the lab-grown diamond center, and it arrived so beautifully packaged with the IGI certificate included. The detail and sparkle are incredible. Thank you for creating such a special piece!

Eva 21 June 2026 Cat Engagement Ring - Misty

This ring is so well made, I’ve worn it daily since I received it and it still looks just as good as the first day! If you’re looking for a stunning non-traditional ring, get this one!!

Christy 27 August 2025 Nature Inspired Pear Cut Moss Agate Ring- Hazel

I bought this with morganite rose gold, for my Fiancé, because she loves cats and saw this and got it after saving some money, to be honest the pictures don't do it enough justice as it was even cuter in real life, my fiancé loved it. 100 will recommend
