Where to Buy Lab-Grown Rubies: A Comprehensive Guide

by Madonna

Rubies, with their vibrant red hue and rich history, have been prized gemstones for centuries. Traditionally, these exquisite gems were mined from the Earth, but with advances in technology, lab-grown rubies have become a popular and ethical alternative. If you’re considering purchasing lab-grown rubies, this comprehensive guide will navigate you through the various options available, ensuring you make an informed and confident decision.

Understanding Lab-Grown Rubies

Lab-grown rubies, also known as synthetic or cultured rubies, are created in controlled environments that replicate the conditions under which natural rubies form. These gemstones have the same physical, chemical, and optical properties as their natural counterparts, making them nearly indistinguishable to the naked eye. The key difference lies in their origin: natural rubies are formed deep within the Earth’s crust, while lab-grown rubies are produced in laboratories.


The charm of natural ruby

The allure of natural rubies lies in their captivating blend of vibrant red hues and rich history. Formed deep within the Earth’s crust over millions of years, each natural ruby is a unique masterpiece, displaying variations in color and inclusions that tell a story of their geological journey. The rarity of high-quality natural rubies amplifies their desirability, as does their association with passion, vitality, and love. Wearing a natural ruby not only showcases its unparalleled beauty but also connects the wearer to a legacy of awe-inspiring natural forces, making it a cherished symbol of both elegance and significance.

Characteristics of Lab Grown Rubies

Lab-grown rubies, also known as synthetic rubies, are created through advanced technological processes that replicate the conditions under which natural rubies form. These lab-created gemstones possess several distinct characteristics:

1. Composition and Structure:

Lab-grown rubies have the same chemical composition (aluminum oxide with traces of chromium) as natural rubies. Their crystal lattice structure closely resembles that of natural rubies, resulting in similar optical and physical properties.

2. Color and Clarity:

These rubies can be engineered to exhibit vivid red hues akin to high-quality natural rubies. The process allows for better control over color consistency and minimizes inclusions, often resulting in higher clarity compared to natural counterparts.

3. Size and Carat:

Lab-grown rubies can be produced in larger sizes and carat weights than many natural rubies, making them a more affordable alternative for obtaining sizeable gemstones.

4. Fluorescence and Luminescence:

Synthetic rubies can exhibit strong fluorescence and luminescence under UV light, which can help gemologists distinguish them from natural rubies.

What is the hardness of lab-grown ruby?

Lab-grown rubies, like their natural counterparts, typically possess a hardness of 9 on the Mohs scale. This exceptional hardness indicates their resistance to scratching and makes them highly suitable for various jewelry applications. The similarity in hardness between lab-grown and natural rubies ensures that they maintain their brilliance and shine over time, allowing individuals to enjoy the beauty and durability of these gemstones in a variety of settings.

Why Choose Lab-Grown Rubies?

Here are reasons to choose lab-grown rubies:

1. Ethical Considerations

One of the primary reasons individuals opt for lab-grown rubies is the ethical aspect. Traditional ruby mining can have environmental and social consequences, including habitat destruction and poor working conditions. Lab-grown rubies mitigate these concerns by reducing the demand for mining and its associated negative impacts.

2. Quality and Affordability

Lab-grown rubies offer consistent quality and clarity. Unlike natural rubies, which can vary significantly in terms of color and inclusions, lab-grown rubies are created under controlled conditions, resulting in gems with fewer imperfections. Additionally, they are often more affordable than their natural counterparts, making high-quality rubies accessible to a broader range of consumers.

2. Environmental Sustainability

The process of mining natural rubies is resource-intensive and can lead to deforestation, soil erosion, and water pollution. Opting for lab-grown rubies helps conserve natural resources and reduces the carbon footprint associated with traditional mining activities.

Where to Buy Lab-Grown Rubies?

Here’s where you can buy lab-grown rubies:

1. Established Jewelry Retailers

Several well-known jewelry retailers now offer lab-grown ruby options alongside their natural gemstones. These companies have recognized the increasing demand for ethical and sustainable alternatives. Stores like Brilliant Earth, James Allen, and The Diamond Foundry provide a variety of lab-grown ruby jewelry, from engagement rings to earrings, backed by reputable certifications and warranties.

2. Online Marketplaces

Online marketplaces are excellent platforms to explore a wide range of lab-grown rubies from various sellers and manufacturers. Websites like Etsy and Amazon Handmade host independent jewelers who specialize in crafting unique and custom-made lab-grown ruby pieces. When purchasing from online marketplaces, be sure to check customer reviews, certifications, and return policies to ensure a satisfactory experience.

3. Direct from Manufacturers

Buying directly from lab-grown ruby manufacturers can often lead to cost savings. Companies like Chatham and The Natural Sapphire Company not only offer loose lab-grown rubies but also provide customization options for jewelry pieces. When dealing with manufacturers, research their reputation, ask for certificates of authenticity, and inquire about their production processes to ensure the quality and origin of the gemstones.

4. Local Jewelers

Many local jewelers have embraced the trend of lab-grown gemstones and may offer a selection of lab-grown rubies in their inventory. Establishing a relationship with a trusted local jeweler allows for a more personalized shopping experience, where you can see the gemstones in person, ask questions, and receive expert guidance.

What to Look for When Buying Lab-Grown Rubies?

Here are a few things to look out for when buying a lab-grown ruby:

1. Certifications

Reputable lab-grown rubies should come with certifications from recognized gemological laboratories. The International Gemological Institute (IGI) and the Gemological Institute of America (GIA) are two widely respected organizations that provide grading and authenticity reports for gemstones. These certificates verify the quality, origin, and authenticity of the lab-grown rubies.

2. Color and Clarity

Color is a crucial factor in ruby evaluation. Lab-grown rubies should exhibit a rich, vibrant red hue without any overtone colors. Additionally, inspect the clarity of the gemstone. While lab-grown rubies tend to have fewer inclusions than natural ones, some degree of inclusions is normal. Choose a stone with minimal, barely visible inclusions that do not affect its overall appearance.

3. Cut and Carat Weight

The cut of a ruby greatly influences its brilliance and overall appeal. Well-cut lab-grown rubies will reflect light in a captivating manner. Carat weight, which determines the size of the gemstone, is also a consideration. Choose a carat weight that suits your personal style and preferences.

4. Setting and Metal Quality

If you’re purchasing lab-grown ruby jewelry, pay attention to the setting and the quality of the metal used. The setting should secure the gemstone firmly while allowing light to pass through for optimal brilliance. Additionally, choose high-quality metals like gold or platinum that complement the beauty of the ruby.
