Discovering the Truth: Are Diamonds Really Found in Basalt?

For years, there has been a popular belief that diamonds can be found in basalt. This belief has been fueled by stories of diamond discoveries in basalt mines, as well as the presence of microscopic diamonds in certain basaltic rocks. However, the question remains: are “basalt diamonds” a real phenomenon, or just a myth?

Firstly, it’s important to understand what basalt is. Basalt is a fine-grained volcanic rock that is formed from the rapid cooling of lava. It is one of the most common types of rock on Earth’s surface and is found in many different geological settings.

Now, let’s look at the evidence for and against the idea that diamonds can be found in basalt. On the one hand, there are numerous reports of diamond discoveries in basalt mines around the world. For example, in the 19th century, diamonds were reportedly found in basaltic rocks in the Ural Mountains of Russia. In the 20th century, diamonds were discovered in basaltic rocks in India, Brazil, and South Africa.

Additionally, scientists have found microscopic diamonds in certain types of basaltic rocks. These diamonds, which can only be seen under a microscope, are believed to have formed from graphite in the Earth’s mantle being subjected to high pressures and temperatures.

On the other hand, there are several reasons to be skeptical of the idea that diamonds can be found in basalt. Firstly, diamonds are typically formed in kimberlite pipes, which are vertical structures that cut through the Earth’s crust. Basalt, on the other hand, is a horizontal rock formation that is found near the Earth’s surface. It is unlikely that diamonds would be transported from the mantle to the surface through basaltic rocks.

Furthermore, the diamonds that have been found in basaltic rocks are extremely small and low quality. They are not the large, high-quality diamonds that are typically mined from kimberlite pipes.

So, what is the truth about “basalt diamonds”? While it is true that diamonds can be found in certain types of basaltic rocks, these diamonds are typically very small and low quality. It is highly unlikely that commercial diamond mining would ever take place in basaltic rock formations.

While the idea of diamonds in basalt may be intriguing, it is not a viable option for diamond mining. The majority of diamonds are still found in kimberlite pipes, and the search for new diamond deposits will likely continue to focus on these areas.

Discovering the Top Locations for Finding Rubies Around the World

When it comes to precious stones, few can match the brilliance and allure of rubies. These fiery red gemstones are highly sought after by collectors and jewelry enthusiasts alike. While rubies can be found in many parts of the world, some locations are particularly famous for their exceptional quality and quantity. In this article, we’ll take a look at some of the top locations for finding rubies around the world.

Myanmar (Burma)

Myanmar is widely regarded as the world’s premier source of high-quality rubies. The country’s Mogok Valley region has been producing rubies for centuries, and the stones from this area are known for their deep red color and exceptional clarity. In recent years, new ruby deposits have been discovered in other parts of Myanmar, including the Mong Hsu region.

Thailand

Thailand is another major source of rubies, particularly in the Chanthaburi province. The rubies from this area often have a pinkish-red hue and are highly prized for their exceptional clarity. In addition to Chanthaburi, rubies can also be found in other parts of Thailand, including Kanchanaburi and Trat.

Tanzania

Tanzania is a relatively new player in the ruby market, but the country has quickly established itself as a major source of high-quality stones. The most famous ruby deposit in Tanzania is the Winza deposit, which produces rubies of exceptional clarity and color. Other areas in Tanzania where rubies can be found include Morogoro and Songea.

Madagascar

Madagascar is another African country that has emerged as a significant source of rubies in recent years. The rubies from Madagascar are known for their deep red color and are often compared to the rubies from Myanmar. The most famous ruby deposit in Madagascar is the Andilamena deposit, but rubies can also be found in other parts of the country, including Vatomandry.

Sri Lanka

Sri Lanka has a long history of producing high-quality gemstones, including rubies. The rubies from Sri Lanka are often referred to as “Ceylon rubies” after the country’s former name. These stones are known for their pinkish-red hue and exceptional clarity. The most famous ruby deposit in Sri Lanka is the Ratnapura district, but rubies can also be found in other parts of the country.

These are just a few of the top locations for finding rubies around the world. While each location has its unique characteristics, they all have one thing in common: they produce some of the most beautiful and sought-after rubies in the world.

Exploring the Myth: Do Rubies Occur Naturally in Granite?

Rubies are one of the most sought-after gemstones in the world, known for their striking red hue and high value. However, there is a persistent myth that rubies can be found naturally occurring in granite. This belief has led many people to search for rubies in granite formations, but is there any truth to this myth?

The short answer is no, rubies do not occur naturally in granite. Rubies are actually formed in metamorphic rocks such as marble and schist, which are created when existing rocks are subjected to high temperatures and pressures over long periods of time. Granite, on the other hand, is an igneous rock that forms from the cooling and solidification of molten magma.

Despite this scientific fact, the myth of rubies in granite persists. Some people believe that rubies may be found in granite due to the presence of a mineral called corundum, which is the mineral form of aluminum oxide and is the same mineral that rubies are made of. However, while corundum may be found in granite, it is typically in very small quantities and is not present in high enough concentrations to form rubies.

So where did the myth of rubies in granite come from? It is possible that the myth stems from the fact that rubies are often found in association with other minerals that may be present in granite, such as garnet and tourmaline. Additionally, some rubies may have been found in loose sediment or alluvial deposits that happened to be near granite formations, leading to the mistaken belief that the rubies were actually formed in the granite.

While the idea of rubies occurring naturally in granite may be an enticing one, it is unfortunately just a myth. Rubies are formed in metamorphic rocks and are not typically found in granite formations.

While rubies are commonly associated with metamorphic rocks, they can also be found in basalt. The occurrence of rubies in basalt has been observed in various parts of the world, including Greenland, Vietnam, and Madagascar. However, it is important to note that the presence of rubies in basalt is not as common as in other rock types. Therefore, if you are planning to search for rubies, it is best to do some research on the geological characteristics of the area you are interested in. Nonetheless, the discovery of rubies in basaltic rocks has expanded the possibilities for ruby mining and has given gemologists and geologists a new area to explore.
