After nearly nine months of careful design, countless sketches, and four full prototypes, we're thrilled to debut The Barcelona — our first low-profile tulip prong engagement ring. Crafted with our signature woven latticework tulip prongs, this design was made with both beauty and practicality in mind.
We heard you: many of our clients—nurses, doctors, teachers, medical students, and active individuals—love intricate engagement rings, but need something that fits seamlessly into their day-to-day life. You’ve asked for a design that doesn’t compromise on elegance, but still fits under gloves, doesn’t snag, and sits comfortably close to the finger.
The Barcelona is our answer.
Why You'll Love It
Low-profile elegance: All the intricate detail you love, now in a sleek, low-sitting design. A seating ring allows the stone to sit lower to your finger.
Signature Tulip Prongs: Our proprietary woven latticework prongs wrap around the center stone like a bloom of petals, offering enhanced security and a romantic aesthetic from every angle.
Thoughtfully Engineered: Every curve, angle, and millimeter has been fine-tuned—especially the tulip prongs, which we’ve reshaped to maintain their elegance even in a compact vertical space.
Tapered Cathedral: A graceful, supportive arch that adds structure without adding height.
The result? A refined silhouette that’s both stunning and practical. Whether you work with your hands, live an active lifestyle, or simply prefer a ring that stays close to you—The Barcelona was designed with you in mind.
We custom cut and hand select the top quality lab diamond center stones for every ring which are guaranteed premium D or E color and completely eye-clean VVS/VS1 clarity.
Our specialty diamond cuts minimize or eliminate the bow-tie effect for optimal performance. Read more about our Bespoke Diamonds here.
We custom cut or custom source stones with ideal cut proportions and ratio for optimum light return and minimal to no bow tie in our elongated cuts.
Stones are guaranteed excellent symmetry and polish.
We are picky with who we work with and only source and produce from a small number of high-quality, eco-conscious growers and screen for blue, gray, and brown color tinges, strain and striation to ensure you receive only the most premium lab diamonds available on the market.
Pavè stones in rings with a moissanite center stone are moissanite by default unless stated otherwise.
Pavè stones in rings with lab diamond center stones are automatically upgraded to lab diamonds.
Pavè stone quality is DEF VS+.

Keep in mind a low-profile ring will have a small gap with a straight band and require a curved ring for a flush fit
