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!

Brooke Griffiths

The team here at Naveya and Sloane were an absolute pleasure to work with. Fantastic communication and the overall process was smooth and simple. End result was a stunning ring that has surpassed our expectations. Thank you guys so much!

Tim Wareing

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