Diamonds don't distinguish between brands and places of origin. You just need to choose your favorite style and the price is right. Because of the "monopoly" of diamonds, diamonds themselves cannot be separated from factories, and the so-called brands are just floating clouds. For the diamond itself, it is just a piece of waste paper packaging diamonds, which has no value!

Only diamonds evaluated by strict 4C standards know their true value, and GIA is undoubtedly the most authoritative in the world, so the value of diamonds certified by GIA is clear. 193 1 year, Robert m shipley founded the American gemological institute (GIA) in los Angeles, USA. This is the first recognized diamond grading standard 4C: color, clarity, cut and carat weight.

GIA is a non-profit organization and the authoritative organization of international diamond grading appraisal. The establishment of 4C standard unifies the measurement standard of global diamond quality. 1939, De Beers took the lead in introducing the 4C standard into the evaluation of diamonds, so that consumers can accurately understand the quality and characteristics of the diamonds they bought.
