There are also proprietary products designed to clean silverware, the most suitable of which are creams. Follow the instructions closely and take great care to first remove all dust, which can create an abrasive paste when mixed with the cleaning cream and scratch your silverware. Diamonds and the 4C Carat weight Diamonds, like other gemstones, are weighed in carats. The word carat dates back to ancient times when it referred to seeds of the carob tree, which are so surprisingly regular, that they were used to weigh gemstones. The carat is divided into 100 points.
Clarity Owing to their natural origin, all diamonds are unique and no two are exactly alike.
The greater the purity of the diamond, the greater its rarity and value. Nearly all diamonds have structural inconsistencies or small crystals of different types. These are known as inclusions or internal features. The number, colour, size and location of these features determines the purity of every diamond. There are various different international classification systems to assess the internal features of the diamond.
