The Allure of Mahaleo Ruby

The Allure of Mahaleo Ruby
Mahaleo Ruby

A Mahaleo ruby is a genuine ruby that has undergone a fissure-filling process. In this process, any cracks in the ruby are filled with lead glass. Before treatment, a Mahaleo ruby typically contains numerous cracks, giving it a dense, even opaque appearance. Its color, initially closer to brown than red, is significantly enhanced by the fissure-filling process, resulting in a more desirable hue. The Allure of Mahaleo Ruby lies in its transformation through this treatment, making it a sought-after gemstone.


Mahaleo rubies have undergone a fissure-filling process to improve their appearance. This treatment involves filling cracks within the ruby with lead glass, enhancing its clarity and color. Before treatment, Mahaleo rubies often appear dense and opaque, with a color closer to brown than red. 

Despite being real rubies, they have certain negative characteristics, such as increased fragility, sensitivity to heat and chemicals, and lower value compared to untreated rubies.

The Treatment Process: Lead-Glass Filling

One distinguishing feature of Mahaleo rubies is the extensive treatment they undergo, specifically lead-glass filling. This process involves infusing the ruby with leaded glass to fill fractures and cavities within the stone. The Allure of Mahaleo Ruby is evident as the lead glass enhances the ruby’s clarity and color, making the stone appear more visually appealing. Here’s a brief overview of the lead-glass filling process:

  1. Initial Cleaning: The rough ruby is cleaned to remove any impurities or dirt.
  2. Fracture Detection: The stone is inspected to identify fractures and cavities that need filling.
  3. Heating: The ruby is heated to a temperature that makes it easier to infuse with glass.
  4. Glass Infusion: Lead glass is melted and infused into the ruby’s fractures and cavities.
  5. Cooling and Polishing: The treated ruby is cooled and then polished to enhance its appearance.

While this treatment significantly improves the stone’s appearance, it also introduces concerns about durability and ethical considerations.

Ethical Considerations

In the professional gemstone world, lead-glass filling is often considered unacceptable for several reasons:

  1. Durability Issues: The filled fractures can make the ruby more fragile and susceptible to damage. The glass can be affected by exposure to acids, bases, and even certain cleaning solutions.
  2. Misrepresentation: Without full disclosure, consumers might be misled about the true nature and value of the gemstone. Transparent communication about the treatment process is essential.
  3. Ethical Concerns: Many in the gemstone industry consider the practice unethical, as it significantly alters the natural state of the stone, making it seem more valuable than it is.
