3-Ex diamonds are the most sought-after quality for connoisseurs and most clients, as cut, polish and symmetry directly affect brilliance and fire of the diamond.Most 3-Ex diamonds sold at Diamania possess “Hearts and Arrows” effect. Fluorescent diamonds have a small chance to be milky or hazy, hence it is more secure to purchase a non-fluorescent diamond for the first time.


Hidden problems of a diamond, eg. milkiness, might not be easily noticeable by just viewing pictures online. The most reliable option is to purchase from a brick-and-mortar store where clients can also enjoy after-sales service.
