How Are Natural Rubies Formed And What Makes Them Different From Synthetic Rubies?

Rubies are one of the most valuable and beautiful gemstones in the world. They are known for their striking red color and have been prized for centuries for their beauty and rarity. Natural ruby is formed deep within the earth, and they are created by a complex series of geological processes. Synthetic rubies, on the other hand, are created in laboratories and are often used as a cheaper alternative to natural rubies.

Natural Gemstones

Natural gemstones are minerals or rocks that have been formed in the Earth’s crust over millions of years through geological processes. They are highly prized for their beauty, rarity, and durability, and have been used for thousands of years in jewelry, decoration, and as a store of value.

Gemstones are valued for their color, clarity, cut, and carat weight, with each gemstone having its unique characteristics. Some gemstones are highly transparent and have a brilliant sparkle, while others are opaque and have a more subdued appearance.

Formation of Natural Rubies:

Natural rubies are formed deep within the earth’s mantle. They are created by a process called metamorphism, which occurs when rocks are exposed to high temperatures and pressures. Rubies are formed when aluminum, oxygen, and chromium atoms combine under intense heat and pressure. This process takes place over millions of years, and it results in the formation of ruby crystals.

Ruby crystals are usually found within metamorphic rocks such as marble, schist, or gneiss. These rocks are typically found in mountainous regions, where the intense heat and pressure required for the formation of rubies are present.

Natural Ruby Characteristics:

Natural rubies have several characteristics that set them apart from synthetic rubies. These characteristics include:

  • Color: Natural rubies are known for their deep red color, which is caused by the presence of chromium within the crystal structure. The color of a natural ruby can range from a pinkish-red to a deep, blood-red color.
  • Inclusions: Natural rubies often contain inclusions, which are small imperfections within the crystal structure. These inclusions can give the ruby a unique appearance and can be used to identify a natural ruby.
  • Cut: Natural rubies are typically cut in a way that maximizes their color and brilliance. They are often cut into faceted shapes, such as ovals or rounds, to enhance their natural beauty.
  • Size: Natural rubies are often found in smaller sizes than synthetic rubies, which can make them more valuable.
  • Rarity: Natural rubies are rare and valuable, which makes them highly sought after by collectors and enthusiasts.

Formation of Synthetic Rubies:

 Synthetic rubies are created in laboratories using a process called the Verneuil process. This process involves melting aluminum oxide powder at a high temperature and then slowly cooling it down to form a crystal.

Synthetic Ruby Characteristics:

Synthetic rubies have several characteristics that set them apart from natural rubies. These characteristics include:

  • Color: Synthetic rubies often have a more vibrant red color than natural rubies. This is because the color can be controlled more precisely in the laboratory.
  • Inclusions: Synthetic rubies are often free of inclusions, which can give them a more perfect appearance than natural rubies.
  • Cut: Synthetic rubies can be cut into any shape or size, which makes them more versatile than natural rubies.
  • Price: Synthetic rubies are typically less expensive than natural rubies, which makes them more accessible to a wider range of consumers.

Conclusion:

Natural rubies are formed deep within the earth’s mantle and are created by a complex series of geological processes. They are rare, beautiful, and highly valued by collectors and enthusiasts.

While natural and synthetic rubies have some similarities, such as their chemical composition and hardness, they have significant differences in their formation, appearance, and value. Natural rubies are rare and valuable, with unique inclusions and a deep red color that is difficult to replicate in a laboratory.

When purchasing a ruby, it is essential to understand the differences between natural and synthetic rubies to ensure that you are getting the quality and value that you desire. Natural rubies are typically more valuable and are often accompanied by a certificate of authenticity from a reputable gemological laboratory. Synthetic rubies, on the other hand, are less expensive and can be a good choice for those who are looking for a beautiful gemstone at a more affordable price.
