The July birthstone is a very valuable stone. The Burmese "Pigeon Blood" ruby stone price is the highest of all varieties. However, because they have undergone some processing to alter their structure, you can find a lot of ruby stones at very low prices on the market.
In recent times, there has been talk of lead glass-filled rubies, which has piqued the interest of gemstone collectors. So, in this blog, we'll talk about lead glass-filled gems. What exactly are they? How are they created? How do you tell the difference between natural and glass-filled rubies?

Corundum, the crystalline form of aluminium oxide, makes up ruby. Ruby is the hardest gemstone after diamond. Natural rubies have been mined for at least 8,000 years.
They can be found in Myanmar, Thailand, Sri Lanka, Afghanistan, and North Carolina, among other places. The colour, cut, and clarity of a Ruby determine its quality.
Because rubies were so valuable, they were the first gemstones to be created artificially. Because the demand for Ruby gemstones has increased globally, there appears to be a price paradox in today's market.
Because the supply of high-quality material cannot keep up with the ever-increasing demand, treatments to make cheap rubies more visually appealing are used.
Some treatments are stable and accepted as standard practise by gemologists, while others are unstable. As a result, many low-cost rubies on the market today are produced by lead glass filling.
The material that is heavily treated to improve transparency is lead glass-filled rubies. This treatment involves taking a very low-grade ruby with surface cracks and repairing it by heating it with lead glass. Glass has a much lower melting point than ruby, which liquefies and fills the crack.
Because glass and corundum have similar refractive indices, it improves the colour and clarity of low-grade material. The question now is, what is the problem with this treatment? For the average consumer, this is a lovely ruby at a reasonable price.
This process, however, is highly unstable and can be damaged not only by a jeweler on the workbench, but also by the consumer with normal wear.
Internal gas bubbles are the most noticeable visual feature of a composite ruby. These can be single spheres or clouds of bubbles, flattened or rounded, and can be found in almost all fissure-filled rubies. They are usually visible even to the unaided eye.
Because it is difficult for customers to tell whether a ruby is natural or glass filled. So your first priority is to buy from someone you know and trust.
