"Diamonds are a girl's best friend"
A diamond is a beloved gem that is perfect for jewellery. It has a beautiful sparkle, is durable and is not damaged easily because of its hardness.
In our Chula Jewellery we only use high-quality natural diamonds that have been obtained in a fair way. You will find the quality of the diamond described in the product description of each piece of jewellery and you will receive a certificate from your chosen diamond in your jewellery. To make it more clear what this quality exactly means, you will find a short explanation below.
The quality of the diamond, the 4 Cs
The value of a diamond is determined by its four main characteristics,
the 4 C´s:
Carat is a term used to express the weight of a diamond. A diamond of 1 carat weighs 0.2 grams. Often for diamonds the weight is indicated in points. The points are (certainly with diamonds smaller than 1 carat) a simple way to indicate the carat of a diamond without working with decimals. A diamond of 1 carat has 100 points, so a diamond of a quarter carat has 25 points.
Diamond is a natural product and therefore there have different degrees of clarity. A diamond that is completely free of internal and external structural errors has the highest quality. Because with a completely transparent diamond, nothing stands in the way of the light and the diamond is at its best. Such a diamond is called flawless or flawless. Inclusions and impurities are at the expense of the beauty of the stone. To determine the clarity, an expert views the diamond with a magnifying glass that magnifies 10x under normal light. The purer the diamond, the higher the price.
|Highest quality||Lowest quality|
|Description||Internally Flawless||Very Very Slight inclusions||Very Slight inclusions||Slight Inclusions||Imperfect|
The quality of a diamond depends on the way in which the stone reflects the incident light. Colourless diamonds are the most wished for as they reflect some light. Diamonds that are not completely white absorb a part of the incident light that´s why they will sparkle less.
The small colour differences are recorded by means of the standards of the International Color Grading Scale. In schedule below you will find the colour gradient of diamonds, color D is completely transparent and colours S to Z have a light yellow tint.
A diamond has an exceptionally high refractive index. That is why polished diamonds shine incredibly in the light. The more beautiful the diamond is cut, the greater the brilliance. After all, the correct proportions must be observed and the finishing must be done meticulously. If the stone is not perfectly cut, the sparkling is reduced and the stone has a lower value.
A diamond can be cut in various shapes, but the best known is brilliant cut. With this shape the diamond is cut in 57 facets. The light reflects from one facet to the other and so the maximum sparkle is achieved. A brilliant cut diamond is also called "full cut" and we use it a lot in our collection.
WHERE DO THE DIAMONDS FROM CHULA COME FROM?
Our diamonds are from a Sightholder of DTC, The Diamond Trading Company.
The Diamond Trading Company (DTC) is the rough diamond sales and distribution arm of the well known De Beers Family of Companies. The DTC sorts, values and sells approximately 75% of the world’s rough diamonds by value.
The DTC sells diamonds that are sourced primarily from De Beers’ mining operations.
The DTC’s Sightholders are required to comply with the De Beers’s Best Practice Principles (BPP)s which set out various objective standards of conduct within three main areas –
1. Business responsibilities;
2. Social responsibilities;
3. Environmental responsibilities.
The BPPs ensure that the De Beers Family of Companies, DTC Sightholders and applicable third parties are operating to the specific ethical, legal, professional, social and environmental standards. The DTC also requires its clients to be 100% committed to the Kimberley Process.
The Kimberley Process has been started to stop the trade of ‘conflict diamonds’ and ensure that diamond purchases were not funding violence or terrorism activities. The United Nations General Assembly adopted a landmark resolution supporting the creation of an international certification scheme for rough diamonds. Negotiations between governments, the international diamond industry and civil society organisations resulted in the creation of the Kimberley Process Certification Scheme (KPCS). The KPCS sets out the requirements for controlling rough diamond production and trade.
