Raw Ruby: Everything You Need to Know About This Precious Gemstone

Raw ruby is a precious gemstone that has been highly valued for centuries. It represents a type of corundum mineral variation, belonging to the same family as sapphires. Known for its deep red color, raw ruby is one of the most sought-after gemstones in the world.

The color of raw ruby is due to the presence of chromium in its crystal structure. The intensity of the red color can vary depending on the amount of chromium present. The most valuable raw rubies are those with a deep, rich red color, often referred to as “pigeon’s blood” red. In addition to its beauty, raw ruby is also prized for its durability and hardness, making it a popular choice for jewelry.

What Is Raw Ruby

As a gemstone, Ruby has been coveted for centuries due to its striking color and durability. Raw Ruby refers to the unprocessed form of the gemstone, straight from the earth. In this section, I will discuss the characteristics of Raw Ruby and how it differs from Cut Ruby.

Characteristics of Raw Ruby

Raw Ruby is typically found in its natural form, as a rough stone. The gemstone is formed from the mineral corundum and is usually a deep shade of red, although it can also be found in shades of pink, orange, and purple. Raw Ruby is known for its hardness, with a rating of 9 on the Mohs scale, making it one of the hardest gemstones.

Raw Ruby is often found in mines, and the quality of the gemstone can vary greatly depending on its origin. The gemstone is typically opaque, with a rough, unpolished surface. Raw Ruby can also contain inclusions, which are impurities or other minerals that are trapped within the gemstone.

Raw Ruby vs. Cut Ruby

The main difference between Raw Ruby and Cut Ruby is the level of processing that the gemstone has undergone. Cut Ruby has been shaped and polished to enhance its color and clarity, while Raw Ruby is in its natural, unprocessed state.

Cut Ruby is often used in jewelry, as it can be cut into various shapes and sizes to fit different settings. Raw Ruby, on the other hand, is often used for its metaphysical properties, as it is believed to have healing and protective powers.

In conclusion, Raw Ruby is a beautiful and durable gemstone that can be found in its natural, unprocessed form. While it may not have the same level of polish and clarity as Cut Ruby, it is valued for its unique characteristics and metaphysical properties.

Formation and Sources

Geological Formation

Raw ruby is a gemstone that is formed by the mineral corundum. Corundum is an aluminum oxide mineral that crystallizes in the hexagonal system. The presence of chromium in the corundum gives the gemstone its red color. Raw ruby is formed in metamorphic rocks, such as marble and basalt, under high pressure and high temperature conditions. The process of formation may span millions of years.

Primary Mining Locations

Raw ruby is found in several parts of the world. The primary mining locations for raw ruby are in Africa, Asia, and Australia. In Africa, raw ruby is found in countries such as Tanzania, Mozambique, and Madagascar. In Asia, raw ruby is found in countries such as Myanmar, Thailand, and Sri Lanka. In Australia, raw ruby is found in the state of Queensland.

The quality of raw ruby can vary depending on the location of the mine. The African mines are known for producing raw ruby with a deep red color, while the Asian mines are known for producing raw ruby with a lighter red color. The Australian mines are known for producing raw ruby with a pinkish-red color.

Raw ruby is mined using a variety of methods, including open-pit mining and underground mining. The mining process can be dangerous and labor-intensive, requiring skilled workers and heavy equipment. Once the raw ruby is extracted from the mine, it is sorted and graded based on its quality and size.

In conclusion, raw ruby is a precious gemstone that is formed over millions of years in metamorphic rocks. It is primarily mined in Africa, Asia, and Australia using various mining methods. The quality of raw ruby can vary depending on the location of the mine.

Types of Raw Ruby

Varieties and Colors

Raw ruby gemstones come in a variety of colors, with the most common being red. However, they can also be found in shades of pink, purple, and even brown. The color of a raw ruby is determined by the presence of certain elements, such as chromium, iron, and titanium.

One of the most sought-after varieties of raw ruby is the pigeon blood ruby. This type of ruby is known for its intense red color and high clarity. Other popular varieties include the Burmese ruby, which is known for its rich red color, and the Thai ruby, which often has a pinkish-red hue.

Grading Raw Rubies

Raw rubies are graded based on a number of factors, including color, clarity, and size. The Gemological Institute of America (GIA) has established a grading system that is widely used in the industry.

The color of a raw ruby is graded on a scale from 1 to 6, with 1 being the most desirable. Rubies with a grade of 1 are considered to have a pure red color with no secondary hues. Clarity is graded on a scale from included (I) to flawless (FL), with the latter being the most desirable.

Size is also an important factor in grading raw rubies. Larger stones are typically more valuable than smaller ones, with prices increasing exponentially as the size of the stone increases.

In conclusion, raw ruby gemstones come in a variety of colors and are graded based on factors such as color, clarity, and size. Understanding these factors is important for anyone looking to purchase or sell raw rubies.

Value and Pricing

Factors Influencing Value

As a gemstone, raw ruby is highly valued for its rarity, durability, and beauty. The value of raw ruby is determined by a variety of factors, including its color, clarity, size, and origin. The most valuable raw ruby gemstones are those that have a deep red color with a slight blue or purple tint, known as “pigeon’s blood” rubies. These are typically found in Myanmar (formerly Burma) and are highly sought after by collectors and investors.

Other factors that can influence the value of ruby raw stone include the presence of inclusions or flaws, which can affect the stone’s clarity and transparency, as well as its overall size and weight. Larger raw ruby stones are typically more valuable than smaller ones, but size alone does not determine value. The quality of the stone’s cut and polish can also impact its value, as well as its overall rarity and demand.

How to Estimate the Price

Estimating the price of a raw ruby can be a complex process that requires a thorough understanding of the gemstone market and its current trends. However, there are a few basic factors that can help you determine the approximate value of a raw ruby gemstone.

First, consider the stone’s color and clarity. As mentioned earlier, pigeon’s blood rubies are the most valuable, but other shades of red can also be highly prized. Look for stones that are free of inclusions and have a bright, even color.

Next, consider the stone’s size and weight. Larger stones are generally more valuable, but keep in mind that a larger stone with poor color or clarity may be worth less than a smaller stone with excellent qualities.

Finally, consider the stone’s origin and rarity. Rubies from Myanmar are typically the most valuable, but stones from other regions can also be highly prized. Look for stones that are rare and hard to find, as these are often the most valuable.

In conclusion, the value and pricing of raw ruby gemstones can vary greatly depending on a variety of factors. By considering the stone’s color, clarity, size, origin, and rarity, you can get a better sense of its approximate value and make an informed decision when buying or selling raw ruby.
