What Are lab created rubies:Things You Need To Know

by Madonna

Rubies, with their captivating red color and timeless beauty, have been highly sought-after gemstones for centuries. However, advancements in technology have allowed for the creation of lab-grown or synthetic rubies that possess similar properties to their natural counterparts. Lab-created rubies offer an alternative to naturally occurring gemstones, providing a more affordable and sustainable option for jewelry enthusiasts. In this article, we will explore lab-created rubies in detail, discussing their creation process, properties, benefits, and considerations for potential buyers.

Understanding Lab-Created Rubies

1. The Creation Process

Lab-created rubies, also known as synthetic or cultured rubies, are produced through a scientific process that replicates the conditions under which natural rubies are formed in the Earth’s crust. The most common method used for creating lab-grown rubies is the flame fusion method, also known as the Verneuil process. In this process, powdered aluminum oxide, also known as alumina, is mixed with small amounts of chromium, which gives rubies their red color.


The mixture is placed in a crucible and heated to extreme temperatures in a flame-fusion furnace. As the alumina melts, it crystallizes on a rotating rod, forming a cylindrical crystal known as a boule. The boule is then carefully cut and faceted to create individual lab-created ruby gemstones.


2. Properties of Lab-Created Rubies

Lab-created rubies share many properties with their natural counterparts. They possess the same chemical composition as natural rubies, consisting of aluminum oxide with trace amounts of chromium. As a result, lab-created rubies exhibit a vibrant red color that is comparable to natural rubies.


In terms of physical and optical properties, lab-created rubies display excellent hardness (9 on the Mohs scale) and have a refractive index and specific gravity similar to natural rubies. This ensures that they have the brilliance and sparkle associated with their natural counterparts. However, some trained gemologists can distinguish lab-created rubies from natural ones through advanced laboratory testing.

Benefits of Lab-Created Rubies

1. Affordability

One of the significant advantages of lab-created rubies is their affordability. Natural rubies of high quality and significant size can command exorbitant prices due to their rarity and desirability. In contrast, lab-created rubies are more accessible to a broader range of consumers as they are generally priced lower than their natural counterparts. This affordability allows individuals to own a stunning ruby gemstone without breaking the bank.

2. Availability and Consistency

Natural rubies are scarce, and the availability of high-quality stones can be limited. Lab-created rubies, on the other hand, can be produced in large quantities, ensuring a more consistent supply in the market. This availability allows jewelry designers and manufacturers to access a steady source of quality rubies, enabling them to create unique and beautiful pieces without relying solely on natural gemstones.

3. Eco-Friendly and Ethical Considerations

The production of lab-created rubies has minimal impact on the environment compared to the mining process associated with natural rubies. Mining for natural rubies can cause environmental disturbances, including deforestation, soil erosion, and water pollution. By opting for lab-created rubies, individuals can make a more environmentally conscious choice, contributing to sustainability efforts within the jewelry industry.

Furthermore, lab-created rubies eliminate the ethical concerns associated with the mining of natural gemstones. The mining industry has faced scrutiny for issues such as unfair labor practices, human rights violations, and funding conflicts in certain regions. By choosing lab-created rubies, consumers can ensure that their purchase aligns with their ethical values.

Are Lab Rubies Great Value?

Lab-created rubies offer excellent value for those seeking a beautiful and affordable alternative to natural rubies. These gemstones provide several advantages that make them a great value proposition:


Lab-created rubies are generally priced lower than natural rubies due to their production process. This affordability allows individuals to own a stunning ruby gemstone without the high price tag associated with natural rubies. It opens up opportunities for a wider range of consumers to enjoy the beauty and allure of rubies.

Quality and Consistency:

Lab-created rubies are produced under controlled conditions, ensuring consistent quality and color. These gemstones possess similar properties to natural rubies, including their vibrant red color and hardness. The controlled environment of their creation process allows for a more consistent supply of high-quality rubies in terms of color, clarity, and cut.


Natural rubies are scarce and can be challenging to find in larger sizes or high qualities. Lab-created rubies, on the other hand, are produced in a laboratory setting, making them more readily available. This availability allows jewelry designers and manufacturers to create unique and beautiful pieces using lab-created rubies without relying solely on the limited supply of natural rubies.

Ethical and Environmental Considerations:

Lab-created rubies eliminate the ethical concerns associated with the mining of natural gemstones. They have a minimal environmental impact compared to the mining process. Choosing lab-created rubies supports sustainability efforts and ethical practices within the jewelry industry.

Overall, lab-created rubies offer great value by providing an affordable, high-quality, and ethical alternative to natural rubies. Their availability, consistent quality, and attractive price point make them an excellent choice for those seeking the beauty and elegance of rubies without the premium price tag.


Lab-created rubies offer an accessible, sustainable, and ethically conscious alternative to natural rubies. Their creation process replicates the conditions that give rise to natural rubies, resulting in gemstones that possess similar properties in terms of color, hardness, and brilliance. The affordability, availability, and minimal environmental impact associated with lab-created rubies make them an appealing choice for jewelry enthusiasts.

However, buyers should consider personal preferences, sentimental value, and the potential investment value when deciding between lab-created and natural rubies. Transparency, accurate disclosure, and certification are essential aspects to consider while making a purchase. Ultimately, whether one chooses a lab-created or natural ruby depends on individual preferences, budget, and values. The beauty and allure of rubies, regardless of their origin, continue to captivate and enchant jewelry lovers worldwide.
