Thailand and Rubies
Thailand was the first country to start the treatment of natural ruby, many other countries like China and India are selling counterfeit rubies or composite rubies. We have all sizes and shapes in stock. Basically, round, oval, square, and cushion are preferred shapes but we do manufacture all shapes to order and we stock as much as possible too. We sell big sizes for rings, earrings, and pendants and selling mixed lots as well. We are producing and selling from regular faceted normal cuts to cabochons to all fancy shapes that you require.
Let’s briefly explain what a “Glass-filled Ruby” actually is:
At face value, the process to create a lead glass-filled ruby seems to be pretty much the same as other precious and semi-precious gemstones. They use heat and a substance to alter the color and fill the fractures that exist in the stone. This creates a more transparent, eye-clean, brighter gem that resembles a more expensive ruby.
Terms you need to know
Heat Treatment: The most common of the treatments. It is done to enhance the color and/or clarity of the ruby. This is used both alone and with fracture filling.
Fracture Filling: A substance is usually heated and flowed into fissures in the stone to increase durability. High heat is used to promote a solid bonding of the post material to the original.
A few pointers
The basic criteria in the market these days is to judge the quality of the glass-filled ruby’s clarity and color. Well, it shouldn’t only be this, it should also be judged by the percentage of lead glass present in the piece. That is why there are some price variations within different suppliers. If there is a lead glass component above a certain percentage (decided by a gemologist association) then it is considered imitation.
(This is a very sensitive topic because it’s almost impossible to practically test these rubies for % of glass in it (as they are inexpensive, but being a graduate gemologist can help you understand the % better, (which is why the H1, H2, H3 are the 3 categories by which the Expensive single pieces are tested by Labs to make sure they don’t have high Lead glass fill % and no one can justify the right or the wrong glass fill/imitation) The buyer should always take care and know what to look for when buying glass-filled rubies. Some properties differ between imitation and naturally treated ruby. A glass-filled ruby will have a glassy appearance (With some inclusions if present), would be quite fragile, and unusually big in size, and the unexpected color is quite common.
Can These Rubies be damaged? & How can they be damaged?
The answer to the first question is yes. Secondly, Heat and chemicals are the most likely causes of damage to the treated ruby. Regular heat that a consumer would come in contact with should pose no threat. Jewelers however can destroy the treatment completely if they try to use a torch around a ruby with lead glass filling. Acidic or harsh chemicals are likely to remove the filling and color. For a jeweler, this is usually when a final acid bath is given to the ring to remove solder flux and other coatings in the repair process. For the everyday person, it could be lemon juice or other household cleaners. Common jewelry cleaning solutions can also damage this treatment causing the stone to crack and fall apart. None of these are usually issues for regular ruby treatments.

We are mostly known for sapphires, but our factory cuts very small melee size fine round & square-cut rubies for all sizes and mostly go out for client custom order, like these Mozambique cut rubies. The process of cutting Ruby is quite difficult, especially color matching, size matching, quality (clarity) matching and a perfect heating process that we have put lots of years of research and development into this Thai controlled process.
