Lazare Kaplan International Inc


Founded in 1903, LKI has been a leader in industry innovation: as pioneers of Ideal cut diamonds, first to laser-inscribe diamonds, and first to offer uniquely brilliant diamonds as a brand with complete marketing support.

LKI’s rich heritage of excellence permeates all its activities from product conception and craftsmanship through to customer service and ethical leadership. This commitment to uncompromising standards translates into beautiful products and quality services.

LKI is an acknowledged leader in setting and adhering to the highest ethical and professional standards, giving customers the confidence that they share in one of the most honourable diamond traditions. As a US publically traded company, it complies with some of the strictest standards of governance, transparency and ethics.

The Lazare Diamond ® is LKI’s flagship product. It is the original ideal cut diamond, cut to such exacting proportions that the brilliance, scintillation and fire of the diamond are optimised to create The World’s Most Beautiful Diamond ®. Each stone over 0.18ct is laser-inscribed with the Lazare logo and a unique number to identify it as a Lazare Diamond. Retailers purchasing Lazare Diamond loose polished or jewellery benefit from a comprehensive package of marketing services.

LKI customers may also purchase diamonds and diamond jewellery from its Preferred Collection®. LKI also offers a range of HPHT diamonds under its Bellataire® Collection.
