Natural vs Glass-filled Rubies
Nowadays new type of ruby is available in the market, called glass-filled ruby. Differentiating between real rubies and glass-filled rubies is crucial because rubies are indeed precious gemstones.
Glass-filled ruby undergo a treatment process involving heating and the injection of lead glass into surface-reaching fractures or cavities within the rubies. These fractures can occur naturally during the mining and cutting process. This process also involves treating lower-quality rubies with acid to remove mineralized inclusions.
Glass-filled rubies might offer a more affordable option but they are not on the same level as natural rubies in terms of value and durability. The glass-filling treatment makes the ruby more delicate and prone to breakage, which might not be suitable for everyday wear.
Difference between Natural vs Glass filled ruby
Imperfections: Genuine rubies often have tiny cracks or mineral marks that can be seen under magnification, confirming their authenticity.
Uniform Color: Natural rubies display a consistent, deep red color that spreads evenly across the gem.
Durability: They are durable and can handle everyday use without being easily damaged by heat or chemicals.
Higher Value: Due to their authenticity and quality, natural rubies typically command a higher price compared to glass-filled rubies.
Surface Fractures: Glass-filled rubies often show visible cracks or cavities on their surface, filled with lead glass. These cracks can be seen with the naked eye or under magnification.
Uneven Color: Glass-filled rubies may have uneven color spots, indicating the glass-filling process.
Affordable Price: They are usually more budget-friendly than natural rubies due to their lower quality.
Delicate Care: Glass-filled rubies are fragile and can be easily damaged by heat, chemicals, or ultrasonic cleaning. Special care is advised when handling them.
Transparency Clues: Tiny air bubbles or swirls within the fractures of glass-filled rubies can be spotted upon close inspection, revealing their treatment.
