Carat: indicates the diamond carat, or the weight of the gem in carats. The name originates from the carob seed, used for measuring because of its consistent weight in ancient times. The carat is divided into 100 points, so a 50 point diamond is a 0.50 carat diamond. In the past, diamonds were weighed with increasingly accurate scales, today diamond carats are measured electronically because of the greater accuracy and sensitivity.
Cut: indicates both the proportions of the diamond cut, and the shape that is given to the gem. The cut, which requires able human intervention, is important as it determines the refraction of light and consequently the gem's brilliance and sparkle. There are also multiple diamond cuts used for different pieces of jewelry: oval diamonds, marquise diamonds, pear shaped diamonds, heart shaped diamonds, princess cut diamonds, carré cut diamonds, radiant cut diamonds, emerald cut diamonds, tapered diamonds, cushion cut diamonds, baguette diamonds, rose cut diamonds.
Colour: In most cases, the degree of diamond colour actually represents the degree of absence of colour. Diamond grading levels are defined by letters, where D is for entire colourless and extremely rare diamonds and Z indicates intensely coloured diamonds.
Clarity: diamond clarity indicates the presence, number, position and size of inclusions, thus determining the degree of flawlessness or clarity of these gems. Any inclusions, tiny internal flaws invisible to the naked eye, are traces of minerals, the legacy of the gems' crystallization process. The number and position of inclusions are shown in the diamond's certificate.
The Kimberley Process is an international initiative that regulates the diamond trade, protecting it from the introduction on the market of diamonds involved in conflicts. The mandate is managed by the United Nations and is currently adopted by 69 Countries, non-governmental organizations, and market sector operators. Every load of diamonds exported across an international border must be accompanied by a diamond certification that ratifies compliance with the Kimberley Process, authenticated by government authorities.
In addition to this, certification system is a guarantee system that requires market sector operators to continue to certify the origin of diamonds throughout their entire lifecycle by means of a compliance certificate. In line with the Kimberley Process, Damiani diamonds and "brilliants" are selected and treated in keeping with a code of ethics that clearly and transparently defines the values that the company stands for. Symbol of light, immutability, eternity, diamond jewelry has always represented the ideal choice for a precious gift, a special occasion, a moment to be remembered.
To further reinforce the quality warranty, the Damiani logo and the certificate number are engraved also on the band, for solitaires with 30 karat-plus purity. For diamonds below 30-karat purity, Damiani customises the solitaire through an exclusive internal engraving on the logo stem and issues an authenticity certificate.
