We use SI/VS+ graded, G+ coloured diamonds, as standard. Ensuring our diamonds consistently shine with a bright brilliance.

Diamonds above 0.20ct are typically all certified by the world’s most reputable grading body - GIA (Gemological Institute of America). Diamonds used for flooded pavé are recognised as melee diamonds are sorted on such a large scale that it becomes impossible to grade each individual stone however all diamonds below the 0.2ct weight will still be inspected and sorted by qualified and fully trained gemologists.

Gold in its purest form is too soft to be used in fine jewellery, but when mixed with other metals it increases its durability, and also allows you to create colours like rose gold and white gold.
