Black diamond rough

Types of Black Diamond Roughs

• Carbonado

  Known as a tough diamond, carbonados or black stones have an opaque look with a slightly granular texture. Uniquely, people found these diamonds in eluvial deposits in Brazil and Central Africa. Moreover, unlike such white polished diamonds, black carbonados have uneven surfaces, which can be aesthetic for some purposes. About 75% of these stones are rough-cut and used in making industrial tools. In addition, 20% cut into fine jewelry.

• Oral Black Diamonds

  Oral black diamonds are typically found in several types of rough ocean deposits. They slurry such diamonds over long periods, giving them an abraded roundish shape. Unlike carbon, oral black diamonds are often clearer inside, rarely show significant inclusions, and can be cut into brilliant fancy-cut jewelry diamonds. However, they are rarities in the ocean deposits.

• Opaque black diamonds

  Opaque black diamonds are rough-black diamond that displays no transparency whatsoever. This type of rough diamond is preferred for industrial applications due to its strength and durability. These types are commonly used as abrasives or cutting tools. Opaque black diamonds can also hold aesthetic value within jewelry and art. This prominence is often attributed to the unique color and surface texture that are visible in the stone.

• Crystal black diamonds

  These are rough-black diamonds that are frequently found to have inclusions in the form of carbon or other minerals, thus contributing to their distinctive black hues. Crystal-black diamonds, unlike opaque ones, may show slight variations in transparency and possess a glassy shine, especially after being cut and polished. Crystal black diamonds are very hard, lending them usefulness in both industrial and decorative realms.

• Raw black diamonds

  These uncut rough-black diamonds look far from the gemstones people usually buy in rings or wear as necklaces. They are in their natural state before any human intervention. People haven't done anything to raw black diamonds. Therefore, they still maintain their original shapes, sizes, and, most importantly, rough surfaces. Although raw black diamonds have no luster, they are extremely valuable and important. They will eventually morph into beautiful glimmering stones.

How to Choose Black Diamond Rough

• Origin

  Black diamond rough comes from several regions. Each offers a unique type. For instance, most people in Brazil and Central Africa prefer natural pieces like carbonado. Others might need synthetic stones grown in controlled lab environments. Choosing a black diamond's origin accounts for both authenticity and ethical consideration.

• Clarity

  They say clarity is rarely considered when making a decision about black diamonds. The reason being this stone's alluring hue is caused primarily by the inclusions within. Black diamonds are often more included than other types of diamonds. So, those that are less included typically make for more valuable stones. Inclusions can affect the way light reflects off the surface of a diamond. Thus, people should look for at least several minor inclusions in this diamond type.

• Cut

  Black diamond rough generally comes in various shapes. Common shapes one is likely to stumble upon include oval, round, princess, and pear cuts, among others. However, no-casting for such diamonds is similar to white ones because these diamonds have not been cut or polished yet. Therefore, a good-quality stone may appear as a dull stone bereaved of any sparkles. Once in the hands of a skilled jeweler, the stone will take a new dimension of beauty. However, when choosing a rough piece, this is another factor to consider if a jeweler plans to carry out the cutting process on their own.

• Size and shape

  Size and shape are personal preferences to each individual. Some people like such rough diamonds because of their compact nature, while others prefer large-sized ones. A majority of black diamond roughs are irregular in shape. Thus, they will require the expertise of a jeweler to decide on the best cut.

• Ethical sourcing

  It's important to consider the source of these diamonds. Therefore, buyers should look for vendors or jewelers who are clear about how they get their materials. This means choosing lab-grown stones as these are friendlier to the earth. These stones, too, can have a beauty as drool-worthy as naturally discovered ones.

Specifications for Black Diamond Rough

• Carat weight

  Rough-black diamonds normally range between 1 carat to 5 carats. But they can also go higher. The larger the carat weight, the more valuable the rough stone gets. However, carat weight only refers to the size and does not make any statements about the diamond's cut, clarity, or color.

• Clarity

  Black diamonds have more inclusions than clear ones. They are identifiable with the naked eye as black spots, carbon crystals, or other mineral remnants. People consider this a type of clarity in black diamonds. Moreover, it significantly impacts its value. The lower the clarity, the higher the likelihood of inclusion being visible. However, such inclusions are often sought in the market for those who aspire to have distinctive-looking pieces.

• Color

  All-black diamonds fall under one color category. Nonetheless, the saturation and hue of black may differ. Some appear more opaque, while others look like they are shining with a deep ebony luster. Occasionally, subtle hints of brown or gray can be found hiding in the diamond. This contribution is responsible for its unique color characteristics. Typically, the more intense the black color, the more valuable the stone grows to be.

• Shape and cut

  In most cases, black diamond rough is irregular in shape. They look like unshaped pebbles. This is particularly true for natural stones. Lab-made stones have more symmetrical shapes. When it comes to cutting, this means the stone has not been fashioned into any specific gem cut yet. Working with an experienced jeweler is recommended for the best results.

• Origin

  Black diamond rough from Brazil and Central Africa is popular among many people. These are mined stones, though. They are also available in the market for synthetically produced stones. These are grown in labs. They offer an ethical alternative to mining.

DIY for Black Diamond Rough

• What to keep in mind before starting

  Black diamond rough is a delicate stone that requires skill and care during processing. Prospective cutters should invest quality time in research and training before undertaking this project. It will ensure they handle the stones correctly without incurring any harm. Seeking assistance from an expert is also recommended. Cutting these roughs can produce sharp edges and dust. People should always wear protective equipment before getting started with the cutting process.

• Equipment needed

  One should get a diamond cutting saw or blade. A regular saw won't make the cut (literally). People will require a faceting machine just in case they wish to achieve intricate designs. An alternative option is to use a lapidary grinder if a faceting machine is out of reach. A diamond polishing pad will give the stone a polished finish. For safety purposes, people will need goggles and a mask to protect themselves from flying dust and debris.

• Cutting process

  People should start by securing the black diamond rough in place. They should use a vise or a dop stick. Then, they need to make an initial cut. This is aimed at forming a flat base on the rough stone. After them making the flat base, they should continue with the cutting process. During this process, they need to slowly shape the stone into the desired cut. Gradually, from each side, working the diamond saw through the top to maintain control. Accidental drops of water will keep the blade cool as people proceed with the cutting.

• Polishing

  When satisfied with the shape, people should switch to polishing. They should start with a coarse polishing pad before transitioning to a finer one. This will enhance the stone's shine.

• Maintenance

  Those who love their black diamond rough should note that maintenance is crucial for longevity and sparkle. Store the stone separately from other jewelry to avoid scratches. Use a soft cloth or a gentle brush to clean it. In addition, avoid harsh chemicals. The dramatic alteration in appearance will come from professional cutting and polishing services only.

Q and A

Q1. How does a black diamond rough differ from a white diamond?

Typically, black and white diamonds are the same in that both are forms of carbon. But a black diamond undergoes an inclusion of carbon crystals or other minerals during its formation. On the contrary, a white diamond that has more clarity doesn't have any inclusions. This explains why black diamonds are less reflective than their white counterparts.

Q2. What are some common uses for black diamond rough apart from jewelry?

Jewelry aside, black diamond rough is widely used in the industrial sector. In cutting tools and abrasives to be specific. Their hardness helps in machining and drilling materials. People also use black diamonds in making optical devices and other electronic equipment.

Q3. Are black diamonds more durable than other types of diamonds?

Yes. They say black diamonds are more durable than clear diamonds due to the tough nature of their crystal structure. Although they undergo more inclusions than other diamonds, this feature makes them tougher to handle. They are ideal for engagement rings and other types of wedding jewelry. Since they are more durable, they can easily withstand daily wear. They also make good stones for rings that need to be worn frequently.

Q4. What is the meaning of a black diamond rough's color?

In most cultures, the black color of a black diamond symbolizes strength, power, and authority. It represents elegance and sophistication. In addition, the depth of black signifies mystery and the unknown. Across cultures, black diamonds carry diverse meanings. But more often than not, they are associated with resilience and a uniqueness that stands out in all varieties.
