The colour system originated half a century ago when diamonds from Africa and Russia were usually tinted yellow. More recent mines are producing a large number of diamonds that exhibit a slight brown hue (called top light brown (TLB)). The colour system does not recognise TLB. While these diamonds can be less expensive to purchase, we recommend that the consumer insist that the jeweller state on the receipt or appraisal if any brown hue does or does not exist in their new purchase. Very rare in nature are fancy colours such as champagne, canary, blue and cognac colours. The Diamond Gallery is pleased to have an array of these precious gems in stock.
