We offer a large range of engagement rings, wedding rings, eternity rings, diamond pendants and diamond earrings in both traditional and contemporary designs. If you cannot find what you’re looking for we’ll create a bespoke jewellery design from a single picture or sketch.


If we don't have the diamond you’re looking for in stock we can easily source it via our offices in London, Tel Aviv and New York. 


Each diamond comes with a Certificate of Authenticity from a leading diamond grading laboratory such as GIA, HRD or IGI. All our diamonds are conflict-free and comply with the industry’s strict Kimberley process regulations.


If you have any questions please do not hesitate to contact me or a member of our sales team.
