DIAMOND GUIDE: THE 4 Cs – UNDERSTAND DIAMONDS BETTER
The quality of a diamond is defined by means of the 4C’s: Carat, Clarity, Color and Cut. These characteristics do not only determine the stone’s quality, they can also be very useful in identifying the diamond, since every diamond is unique.
The weight of diamonds is expressed in carats. One carat is equal to 0.20gr. Diamond weight is also displayed in points. One carat is equal to 100 points. Thus a stone of e.g. 1.50 carat means it is 1 carat and 50 points.
On the certificate or ID report, the weight is mentioned in up to two decimals. E.g. 1.50 ct = 1 carat and 50 points… more about Carat….
Pure diamonds are extremely rare. Almost all rough diamonds contain impurities or
“Inclusions” which are traces on non-diamond material that were “trapped” in the mineral during the stone’s formation. Many inclusions are removed during the cleaving, sawing, cutting and polishing of the diamond.
The fewer inclusions or structure phenomena the stone displays, the higher the quality of the diamond… more about Clarity….
Over 90% of all gem diamonds have a basically yellowish color. The intensity can vary from nearly colorless, which is preferable, to decidedly yellow. The value of a white stone is higher than that of a yellowish stone. However, diamonds can also have a distinct orange, brown, pink, green or blue color. These color diamonds can be extremely valuable.
The color grade describes the color tones in a stone. D is perfectly colorless, which is rare and expensive. The color scale goes from D to Z and indicates yellow and brown tones. It takes a trained eye to distinguish between shades that are close together, but an untrained eye see the difference between shades that are several tones apart with a little practice… more about Color….
CUT (not to be confused with shape)
The proportions and finish grade of a diamond establish the quality of the cut. A good finish grade testifies to the workmanship of the diamond polisher. It refers to the symmetry of the facets and their overall finish. The best cut diamonds also have the right proportions between the different parts of the diamond. If these proportions are not optimal, the fire and brilliancy of the diamond are affected, and undesirable visual effects might occur. Apart from the most popular ’round brilliant’ cut, there are a range of other frequently used cuts, and one might also come across magnificent ‘fancy cut’ diamonds… more about Cut….
I just bought a gift of a pair of diamond solitaire earrings. They were delivered to me in the US 2 days after they were sent, and they are stunning. They are full of color and sparkle. It was very easy working with Belgium Diamond, and I would definitely purchase from them again.
I bought my engagement ring at Belgium Diamonds and I was very satisfied both of the service and the price (!).
They took all the time required to explained to me the different kinds of diamonds, their differences and how they are priced.
Then we chose together the ring to make it truly unique.
Price wise, I compared with the other shops in the area and I definitely got the best value for money.
Diamond delivered with a certificate.
A strong go for anyone looking for stones.
Time was of the essence and Alain was very reactive to step in and professionally advised me on which diamond would look the best in the jewel i wanted to buy. He explained to me with patience what were the best options in terms of price and quality and he executed the order in a timely manner ! A great experience all along. I trust i will work with him again!
It was wonderful experience to buy a diamond on internet from a very professional company. They were prompt to answer to any request. The web site is excellent giving all information a non professional jeweller can understand. The choice is very very large and I bought exactly what I wanted. Also the shipment was very professional.
Belgium Diamonds was outstanding: As a first time buyer I appreciated their professionalism, expertise, and quality to match the prices. Highly recommended. I received my matching white and black tennis bracelets 8 days after I ordered in Louisville Ky.
I was looking for an engagement ring for the past two weeks.
I had a few options and I was told 2-3 weeks in every case, until i got to Belgiumdiamonds.
I was already expecting the same lead time,
but everything changed after i sent them an e-mail and spoke with Henry the following morning.
Ring ready in 2 days and it arrived in the USA 3 days later.
They deserve five stars and definitely recommend for anyone expecting for the best diamond prices and fast delivery.
I will come back for additional diamonds.
Alain and Belgium Diamonds were absolute best when buying a tennis bracelet. He gave me all the assistance I needed throughout the process. He took the time to explain to me about the diamonds and was great in making sure the bracelet arrive on time for Mothers Day with a personal courier.. Very happy with Belgium Diamonds and strongly recommend the company.
