In the glittering world of jewelry, rubies have always been revered for their value and charm. With the development of science and technology, laboratory-cultivated rubies have gradually entered people’s field of vision, which has also led to a controversial question: is laboratory-cultivated rubies really ruby? This question involves an in-depth discussion of the nature of rubies, including their chemical composition, crystal structure, physical properties, and market and cultural perceptions.
Investigation of chemical composition and crystal structure
Made of the same elements
A lab created ruby has the exact same chemical composition as a natural ruby. Both consist of aluminum oxide (Al₂O₃) with traces of chromium (Cr) that gives them the red color. This means that on a fundamental chemical level, they are identical. For example, when scientists analyze both types of rubies, they find the same proportions of aluminum, oxygen, and chromium atoms. So, in terms of what they are made of, a lab created ruby seems to be a real ruby.
Similar Crystal Lattice
The crystal lattice structure of a lab created ruby is also very similar to that of a natural ruby. They both form in a hexagonal crystal system. The atoms are arranged in a specific pattern that determines the ruby’s physical properties like hardness and optical behavior. The laboratory process carefully mimics the natural conditions to grow crystals with a structure that closely resembles that of natural rubies. This structural similarity is another factor that blurs the line between lab created and natural rubies.
Comparative analysis of physical properties
Hardness and durability
Lab created rubies possess the same hardness as natural rubies. Rated 9 on the Mohs scale of hardness, they can withstand scratches and abrasions just like their natural counterparts. Whether it’s a natural or a lab created ruby, they are both highly durable and suitable for use in various jewelry settings. For instance, a ring set with a lab created ruby will not easily get scratched during daily wear, similar to a ring with a natural ruby. This similarity in hardness and durability is an important aspect in considering their authenticity as rubies.
Optical property
The optical properties of lab created rubies are also very comparable to those of natural rubies. They have a similar refractive index, which means that when light enters the gem, it bends and reflects in a way that creates a beautiful play of color and sparkle. A well-cut lab created ruby can display the same kind of brilliance and fire as a natural ruby. This is because the internal structure and chemical composition that govern optical properties are so alike. So, in terms of visual appearance and the way they interact with light, lab created rubies seem to be real rubies.
Differential consideration of the formation process
Formation of natural rubies
Natural rubies are formed deep within the Earth’s crust over an extremely long period of time, often millions of years. They require specific geological conditions such as high temperature and pressure, along with the presence of certain minerals. These conditions are only found in a few regions around the world. For example, some of the most famous natural ruby deposits are in Burma, where the complex geological history has led to the formation of these precious gemstones. The natural formation process is slow and unpredictable, which contributes to the rarity and high value of natural rubies.
The birth of a lab-grown ruby
Lab created rubies, on the other hand, are made in a controlled laboratory environment. Scientists use techniques like flame fusion or the Czochralski method to grow ruby crystals. In flame fusion, for example, powdered aluminum oxide and chromium are melted together using a high-temperature flame, and the molten material cools and crystallizes to form a ruby. This process can be completed in a relatively short period of time compared to the millions of years it takes for natural rubies to form. While the end product has similar chemical and physical properties, the origin and formation process are vastly different.
The influence of market and cultural perception
Market values and concepts
In the market, natural rubies are generally considered more valuable due to their rarity. They have a long history of being prized possessions and are often associated with luxury and high status. The price of a natural ruby can vary greatly depending on its quality, size, and origin. For example, a high-quality natural ruby from a renowned origin can command a very high price at auctions. Lab created rubies, while more affordable, are sometimes seen as a less prestigious alternative. However, as awareness about sustainable and ethical jewelry grows, lab created rubies are gaining more acceptance, especially among consumers who value these aspects and want a more affordable option.
Cultural Significance
Culturally, natural rubies have held significant meaning in many societies throughout history. They have been associated with love, passion, and power. For example, in some ancient cultures, rubies were believed to have protective and healing properties. Lab created rubies, being a relatively new phenomenon, do not have the same deep-rooted cultural significance. But as they become more common, they may start to develop their own cultural associations and meanings, especially in modern cultures that embrace technological advancements and innovation.
In conclusion, from a scientific perspective based on chemical composition, crystal structure, and physical properties, a lab created ruby can be considered a real ruby. However, when considering factors such as formation process, market value, and cultural significance, there are clear differences between lab created and natural rubies. The definition of a “real” ruby depends on one’s perspective. Whether it’s a collector seeking a rare and valuable gem with a long history or a consumer looking for an affordable and beautiful option with similar physical properties, understanding these differences is crucial in making an informed decision about whether a lab created ruby meets one’s expectations and requirements.
