Cutting a diamond to shape requires very advanced craftsmanship. Through the industrial revolution in the 19th century, the methods for shaping were refined and the diamonds started to compete with the cultured pearl as the most popular ornament in jewellery. An un-shaped diamond looks almost the same as any other stone, but cutting releases its true brilliance and fire. The most common shape is the "round brilliant", with 57 facets, but diamonds can also be oval, marquise, pear, heart, emerald, princess or radiant shape.
Our coloured diamonds are radiated with laser to enhance their colours. We have several competent craftsmen that set the stones into our eternity rings. This means that we can satisfy our customers´ wishes regarding eternity rings. Below, you can read about different settings and stones.
The stones are set tightly in a row, set with spheres of the metal in question. The ending of the setting can vary: diagonal, straight, pointed, sloping or round.
Also called Lord setting. The stone is totally lowered into the ring and can be set one by one, in rows or sprinkled..
Centre punch setting
The stone is set with two, three or four spheres of metal in question.
The stone is set with four spheres of the metal in question as a star cut out in the ring.
Square shaped settings where the stones are held with spheres of the metal in question.
The stone is set in a tube that is soldered into the ring, which makes the stone stand up from the ring.
The stones are set in 4 claws (crabs), which stands up from the ring.
The ring looks cut off and the stone is set in the edges. A bridge under it stabilizes the splint.
Estimating the quality of a diamond is made on the basis of four factors: carat-weight, colour, clarity grade and cut.
The carat weight is something that most people know about. 1 carat is 0,2 grammes or 0.0071 ounces. The word carat stems from the Arabs word for the seed of the carob-tree (kharrub) which the Arabs used as weights on their common balance. These weighed 0.195 grams or 0.0069 ounces. The dimensions of diamonds with the same weight can vary due to their cut: for instance, they can be "low and wide" or "high and thin".
Large diamonds are much rarer than smaller ones, which affects the price. Smaller stones with a total weight of 1 carat cost less than if you choose one single stone that weighs 1 carat in total. The weight is given in carat (ct).
Most diamonds have a weak colour-tone in yellow, brown or blue. Diamonds with a distinct colour are the rarest in the world. The totally colourless diamond is also very rare. Usually, white diamonds are used, divided in colour-tone.
D -exceptionally white + G –rare white K-L –tinted white
E -exceptionally white H –white M-Z – tinted colour
F –rare white + I-J –slightly tinted white
Only 20 % of the diamonds in the world are of such high quality that they are used for jewellery. The rest are used in industry. To accurately judge the colour of a diamond, it has to be compared with a master stone.
The number and / or size of the inclusions which generally exist within a diamond affects its clarity. Often, the inclusions consist of other minerals, such as olivine and garnet. The clarity is judged with a 10x magnifying lens, called a loup.
IF "internally flawless" is the best clarity and shows no scratches or inclusions.
VVS1 allows very small scratches but no inclusions.
VVS2 means that it is very hard to find inclusions.
VS 1-2 means that it is hard to find inclusions.
SI 1-2 means that inclusions can easily be found.
P1-3 differs from the rest because inclusions can be seen with the naked eye.
"Clear inclusions" means that an experienced observer can see the inclusions in an unset stone through a 10x loup. For an untrained observer, it is very hard to see any difference in clarity of stones of less than 0,20 ct.
