A Buyer’s Guide to Black Diamond Quality

The black diamond is guessed to be a must-have accessory on the jewelry box of each woman as the short black dress. However, this magnificent, luxurious, and gorgeous gemstone is underestimated. Due to the specific quality characteristics of this diamond, it is treated as a lowly transparent gem. Such a quality feature differs this gem from its relatives. Its natural cool effects are caused by micro inclusions into these dark-colored minerals which origin is less explored. Some jewelry experts and geological researchers advance two interesting theories. The first theory clarifies that the origin of these gems is connected with interstellar space. The second one is more pragmatic and proves their geological deposits located in Brasilia and in some areas of Central Africa. Nevertheless, two theories have one grain of truth that regards the fact these dark diamonds are mined in the upper layers of soil.

In any case, the black diamond is a brilliant alternative to the ordinary white transparent gems. It highlights a reserved beauty and mystique. The deeply colored unprocessed gems are actually a rare thing for the jewelry industry. The temperature processing actions improve the quality of lots of these black “swans” in order to reach the intensive homogeneous shades. According to the price range, these jewelry stones cost cheaper than their white “siblings”, but their real attractiveness and value refer to the unique and uncommon color.

Everything you should know about black diamonds

Before you purchase a new piece of jewelry such as necklaces, rings, earrings, etc, embellished with dark-colored gems you need to know some details about the quality to verify the genuineness of your new diamond accessories.

Hardness. These gems are extremely solid as measured by the Mohs scale(10 points out of the 10 possible ones) and, therefore, have long-term strength. However, this feature could negatively affect the processing operations. The processing method of the black brilliants is very complicated, and, as a result, the gems could lose 50% of their weight after the cutting manipulations.
Color. Despite the equal hardness and density, the black gems are not transparent and do not play colors as distinct from the classic white ones. The shining effects are obtained when the number of panes is increased. That’s why the big gems are usually processed with over 100 facets. It should also mention that there are some cases related to the imitation of the original color of these gems using various chemical techniques, e.g, special films. Such actions lead to jewelry damages, breaks, or scars, which increase the appropriate maintenance costs.
Clarity. The authentic gems keep their non-transparency, and their color shades varying from dark-brown to deep black do not change this feature after all. So, the high clarity of these true black-colored gems is a fiction discovered by the fraud persons offering your fake accessories. The deeply colored gems with low clarity are perfectly matched bands made of white gold or platinum, which highlight the gem’s uniqueness and mystery.
Weight. These gemstones are heavy-weighted ones. The biggest cut stone embedded in a ring made of white gold is well-known as the Spirit of de Grisogono. The weight of the rose-shaped gem was constituted to 582 carats before its cutting and 312 carats thereafter.
Price. This criteria directly determines the quality of the diamond purchased. The high price is set for the gems accompanied by the relevant GIA certificate that makes sure the reliability of your new accessory item. The black gems of low quality and less carat-weighted could be estimated at 20 USD per carat on average. The middle qualitative ones may be offered at the market with the price range of 150-200 USD per carat. The most expensive gems are deemed those, the price of which is equal to approximately 600 USD per carat.

To summarize the aforesaid, you should realize that the right choice of the extraordinary accessory is based on the particular list of quality criteria mostly applied to the different colored gemstones. However, the primary rule highlights that the perfect gem is the one, which satisfies your tastes, mood, and desires. So, don’t be afraid of standing outs from the crowd and follow your heart and intuition.
