Black Diamonds Defined

The demand for colorless diamonds has always been high, given their rarity and inherent value. However, colored diamonds, including black diamonds, have historically been overshadowed. But in the 21st century, there has been a significant surge in popularity for colored and black diamonds, thanks to innovative marketing strategies that have breathed new life into these gemstones.

As a result, colored and black diamonds are no longer considered inferior. Renowned designers have incorporated them into their work, further fueling the growing trend. The increasing demand for black diamonds has also contributed to their value, prompting investors to recognize them as exceptional investment opportunities.

With the growing appreciation for black diamonds, their prices have also risen accordingly. These rare and exquisite black beauties are finally receiving the recognition they deserve.

If you’re interested in learning more about testing black diamonds, you can check out the article provided. Additionally, the FAQ section below provides further insights into black diamonds:

  1. Why are black diamonds black?
    Black diamonds, also known as carbonados, contain graphite and amorphous carbon, which give them their black color. The presence of substantial graphite impurities in their composition accounts for their black appearance.
  2. Are black diamonds natural?
    Yes, black diamonds are natural, just like colorless diamonds. However, natural black diamonds are extremely rare. The high demand for black diamonds has led to the creation of treated black diamonds, which are heated to achieve the black color.
  3. Where are natural black diamonds mostly found?
    Natural black diamonds are primarily found in Central Africa and Brazil.
  4. How much do black diamonds cost?
    The cost of black diamonds depends on their rarity. Treated black diamonds have an average cost of around $300 per carat, while natural black diamonds can cost approximately $3,000 per carat.

Black Sapphires Defined

While black sapphires are considered fancy and attractive, they lack the prestige associated with black diamonds. In comparison to their diamond counterparts, they are considered inferior gemstones. Consequently, sapphires hold much less value, which is advantageous for those on a limited budget. You can acquire a black center stone for a significantly lower price!

It’s important not to confuse black sapphires with black star sapphires. Despite their similar names, these two gemstones are entirely distinct.

Black star sapphires belong to the category of “star sapphires.” They earned this name due to their crystal structures reflecting light in the form of a star.

Black sapphires are predominantly mined in Australia, while black star sapphires can be found in various parts of the world, including Thailand, West Africa, and India. Star sapphires are generally rarer and therefore more expensive, leading us to the most significant difference between these two captivating black gemstones.

While black sapphires fall within the lower price range, black star sapphires can cost a small fortune. They are considered precious gemstones that can fetch thousands of dollars.

Black Sapphires: FAQ

  1. Why are black sapphires black?

  2. Are black sapphires natural gemstones?
    Yes, black sapphires are natural gemstones, and unlike black diamonds, they are found abundantly.
  3. Where are natural black sapphires mostly found?

    The good news is that black sapphires are quite affordable, especially when compared to black diamonds. They typically cost around $40 per carat.

Black Diamond vs. Black Sapphire 

Durability

Both diamonds and sapphires are incredibly durable gemstones. Black diamonds, in particular, have a dense composition that places them at the highest level of hardness on the Mohs scale, scoring a perfect ten. They are considered the toughest among all diamond varieties.

Black sapphires also boast excellent durability, ranking at number nine on the Mohs scale. They are highly resistant to wear and tear, surpassing most other gemstones (excluding diamonds, of course). They are not brittle and are less prone to breakage, making them a safe choice.

While both black diamonds and black sapphires exhibit high hardness on the Mohs scale, it’s important to note that they are not indestructible. While they can resist scratching quite well, they are not impervious to all types of exposure.

Color

The allure of both diamonds and sapphires lies in their appearance, making them popular choices for jewelry. Black diamonds are classified as Fancy Black and exhibit a range of colors, varying from faint gray to solid black. The most sought-after black diamonds have even color saturation and a captivating luster. To enhance this effect, most black diamonds are cut with facets.

Black sapphires resemble onyx stones, appearing predominantly solid black and absorbing light that comes into contact with them. They do not possess a noticeable luster as they do not reflect light. Nevertheless, they are often faceted or cut en cabochon to showcase their unique beauty.

Price

As previously mentioned, black diamonds come with a significant price tag, typically costing around $3000 per carat or even more. They are considered a luxury investment.

On the other hand, black sapphires are highly affordable, making them an excellent choice for those on a tight budget. They are priced at approximately $40 per carat, providing an accessible option for jewelry shoppers with budget constraints.

Maintenance

Both black diamonds and black sapphires are highly durable gemstones that can withstand daily wear. They require minimal maintenance to maintain their beauty over time.

For cleaning, it is recommended to soak the gemstones in warm water with a small amount of mild detergent. Allow them to soak for about ten minutes and then gently clean them with a soft brush. While this routine is a good starting point, if you encounter difficulties, it’s advisable to seek the assistance of a professional jeweler. Diamonds and sapphires may contain inclusions and potential weaknesses that can react unfavorably to mechanical cleaning, so professional care is recommended.

Perfect Settings

The choice of setting for black gemstones ultimately depends on personal preference. While many jewelers opt for white metal settings to create a contrasting effect with the black color, yellow or rose gold settings can also be chosen. White gold settings offer a more modern aesthetic, while yellow and rose gold settings provide a softer, vintage touch. Selecting the setting that aligns with your taste and style is key.

Synthetic Versions

Natural black diamonds carry a significant price premium. As a result, many black diamonds found in jewelry stores are created through heat treatment of lower-quality colorless diamonds. These treated diamonds offer a more affordable alternative while closely resembling natural black diamonds.

Synthetic black diamonds, which are entirely manufactured, also exist in the market. Purchasing synthetic black diamonds is a cost-effective option as they are significantly less expensive than natural stones while maintaining a nearly identical appearance.

In the case of black sapphires, due to their lower price and higher availability, synthetic versions are not commonly found. However, it is common for natural black sapphires to undergo heat treatment to enhance their color.

Weighing Down All the Pros & Cons: Should You Buy a Black Diamond or a Black Sapphire?

If black gemstones appeal to your taste, both black diamonds and black sapphires offer numerous advantages. So, how do you make a decision?

If you have a limited budget, the choice is straightforward – opt for what you can afford. In this case, black sapphires are much more affordable than black diamonds, making them the preferred option.

For those with a flexible budget, you can simply choose the gemstone that appeals to you more. Black diamonds offer greater depth and brilliance, while sapphires tend to be more opaque. Black diamonds are also considered more prestigious.

Furthermore, individuals who appreciate black onyx but desire a more durable gemstone should consider black sapphires. These two gemstones are almost identical, with the exception that black sapphires surpass onyx in terms of durability.

In summary, both black diamonds and black sapphires will enhance the beauty of your jewelry and appearance. Choose the one that you prefer and can afford!

Where Can You Purchase Black Sapphires or Black Diamonds?

Once you’ve made your decision on the gemstone, you need to find the one you desire. Locating black gems in physical stores can be a challenging task. Even if you manage to find such jewelry, the options are likely to be limited.

Why is that the case?

Jewelers typically avoid stocking jewelry with colored stones, and black gemstones are no exception to this unspoken rule. While black is a popular choice, it is not a conventional color for jewelry. If you want a chance to find a beautiful piece that meets all your requirements, turning to the internet is your best bet. Online platforms offer endless options, ensuring you won’t have to compromise on your preferences.

Final Words

Black diamonds and black sapphires are both exquisite gemstones that enjoy significant popularity. In terms of durability, there isn’t much distinction between the two. So, what sets them apart?

The key difference between black diamonds and black sapphires can be summed up in one word: prestige. Black diamonds are exceptionally rare and, as a result, considerably more expensive than black sapphires. They also possess remarkable brilliance.

Therefore, when deciding between these two gemstones, the primary factor to consider is your budget. If budget is not a concern, feel free to choose the one that appeals to you the most!
