Lab-Grown Ruby vs. Spinel: Which One Should You Choose?
When it comes to vibrant red gemstones, lab-grown rubies and spinel are two stunning options often compared by jewelry lovers. While both are known for their intense color and brilliance, they have distinct differences that make them appealing for different reasons.
Lab-Grown Ruby: The Science of a Perfect Gem
Lab-grown rubies are chemically, physically, and optically identical to natural rubies, with the only difference being their origin. Created using advanced techniques like the Verneuil process, flux growth, and the Czochralski method, these gems are cultivated in controlled environments that replicate the Earth’s natural formation process.
Unlike natural rubies, which often contain inclusions and imperfections, lab-grown rubies can be produced with fewer impurities, resulting in stunning clarity and vibrant red hues. Some lab-created rubies are even designed to mimic the natural inclusions found in mined rubies, making them nearly indistinguishable without specialized gemological testing.
Spinel: A Natural Alternative with a Rich History
For centuries, spinel has been mistaken for ruby—some of the world’s most famous “rubies” (such as the Black Prince’s Ruby in the British Crown Jewels) were later discovered to be spinel. While it is a completely different mineral from corundum (ruby’s mineral family), spinel boasts an impressive hardness of 7.5 to 8 on the Mohs scale, making it durable for everyday wear.
Spinel naturally occurs in a variety of colors, but red spinel closely resembles ruby. It offers excellent brilliance and luster, often at a fraction of the cost of both natural and lab-grown rubies. Unlike rubies, which may be treated to enhance their color, high-quality spinel is often untreated, making it an attractive choice for purists who prefer an all-natural gemstone.
Key Differences Between Lab-Grown Ruby and Spinel
Composition and Hardness
Lab-Grown Ruby: Made of corundum, scoring 9 on the Mohs scale, second only to diamonds in durability.
Spinel: A separate mineral species, slightly softer at 7.5 to 8 on the Mohs scale.
Color and Brilliance
Lab-Grown Ruby: Intense red color, often with fewer inclusions and high transparency.
Spinel: Red spinel can closely resemble ruby but sometimes has more pink or orange undertones.
Price and Availability
Lab-Grown Ruby: More affordable than natural rubies but still considered a luxury gem.
Spinel: Generally less expensive than both natural and lab-grown rubies, offering a budget-friendly alternative.
Why More People Are Choosing Lab-Grown Rubies
With sustainability and ethical sourcing becoming top priorities for modern consumers, lab-grown rubies are gaining popularity. These gemstones offer the beauty of a natural ruby without the environmental and ethical concerns associated with mining. Plus, their perfect clarity and deep red color make them a top choice for fine jewelry.
According to a survey by MVI Marketing, more than 70% of millennials prefer lab-grown gemstones. Because they are affordable, sustainable, and have the same composition as natural gemstones. The psychological satisfaction that comes from wearing high-quality, ethically sourced gemstones is reshaping the jewelry industry. Making lab-grown rubies a smart, future-proof choice.
