Your Guide to Diamonds

Diamond is a magical word. It evokes images of glamour and wealth; it makes you think of kings, movie stars or treasures. The story of Diamond is also one of adventurers, discoverers, craftsmen, merchants and people in love.

The most beautiful thing about a polished diamond is the way it sparkles, which is caused by the way it breaks rays of light and reflects them. If you look really carefully you can see all the colours of the rainbow in that reflection. So a polished diamond is even more beautiful than beautiful. It is the emperor of all precious stones! And that is why jewellers all over the world like to use diamonds in jewellery such as rings, crowns, bracelets, earrings, and so on.

Cut

Determines how well the diamond has been finished and therefore its brilliance. Along with the cut we must assess polish and symmetry. The grade of polish refers to the smoothness of the facets. If the polish is poor the diamond can lack lustre.
