Bespoke Assortments

Every customer has their own specific needs and criteria for the diamond to pass their quality control (fluorescence, mm length, inclusion specifics, carat weight). Our sorting team prepares our diamonds as per your criteria so that when you receive the parcel it is ready to sell.

Our team of certified graders maintain inventory standards with state-of-the-art microscopes and fluorescence machines. Any stone that does not match the level of our regular inventory will not be added into the parcel.

In order to strengthen our transparency and accountability, we have concentrated our procuring of polished diamonds to a minimal number of reliable vendors. This allows to effectively authenticate and trace the origin of our inventory.


We have an established operation with Livingstones that functions across the entire diamond supply chain. Rough is procured in Antwerp and is then manufactured in Mumbai and Surat. The polished products are then diligently assorted as per the client’s requirements and are subsequently sold and distributed across Europe, Asia and the United States.
