Constantin Collection

The Constantin Collection reimagines modern engagement rings through sculptural form and architectural design. Defined by a distinctive double-band silhouette, each ring balances bold structure with the lightness of softly shaped centre stones that appear suspended within the setting.

Designed in-house by Naveya & Sloane and crafted by our artisans, the collection reflects a contemporary approach to heirloom standard engagement rings.

I purchased my fiancés engagement ring through Naveya and Sloane and had the best experience. From the start Elle provided great guidance to both me and my partner. Her service was outstanding throughout the whole process. I couldn’t recommend this company more.

The team at Naveya & Sloane were amazing to deal with, never went into the store and meet in person, yet the whole process was so easy and the communication was amazing. Would Highly recommend Naveya & Sloane to anyone!

Excellent experience choosing a ring here. Got good, practical advice from Elle and had great communication while waiting for the ring to be completed.
