Rubies? At the Natural Sapphire Company? Well simply put YES, and WHY NOT?
Rubies and Sapphire are from the same species (Corundum) and differ only in their color causing elements. As a sapphire company we have always had an eye and ear on the ruby trade, trying to work on a way to bring our sister gem to our inventory. However as a company known for rare untreated materials, we were previously not able to gather inventory to provide our clients.
We are proud to say our customers are highly educated on gemstones and their treatments, and so they desire natural stones, as created by earth without interference and alterations by man. Stones that are not manipulated in any way, are unique and truly spectacular one of a kind pieces. This quality of material was just not available to us until now.
Early this year we received a call that has started to change the ruby market. A new deposit of rubies and sapphires had been found in Tanzania. Immediately we started making our calls and sent scouts to the area. Word of mouth had begun to spread news about the color, clarity and size of the natural untreated rubies that were available.
The results are astonishing! I recently was able to view a specimen that we received from the area and it left me speechless. All I can say now after having time to process what I have just seen is COLOR! The color is vivid, electric, red with incredible brilliance and flash. It is an experience of a life time being able to see a discovery of this magnitude.
As a gemstone enthusiast this natural untreated ruby made my career!

Large rubies of fine color and clarity are extremely rare, therefore the market consists readily of lower priced treated rubies in order to provide the market with affordable stones. “According to AGL President C.R. “Cap” Beesley, those who developed the treatment were able to take very low-quality ruby that was available in mass quantities and turn it into more transparent, facet-grade ruby. This sparked industry concern over the impact the stones might have on consumers who purchase them believing they are getting a higher-quality ruby.”National Jeweler Network
Treatments can change the appearance of a gemstones clarity and color to be more desirable. However the treatments often can have negative effects, such as durability and artificial inclusions. All treatments must be disclosed to the customer.
“The American Gem Trade Association’s Gem Trade Lab and the Swiss Gemological Institute (SSEF) issued alerts to the trade regarding glass-filled rubies. While the practice of filling small pits and fissures in ruby with glass have been known for over a decade, the sudden emergence of many rubies in the market that are treated this way has raised concerns anew.”
“Lead-glass filling is very pervasive and due to the refractive index of the glass and ruby being similar it is often difficult to fully recognize the extent of this treatment. This image illustrates one of the most distinctive features of the composite rubies, consisting of large numbers of gas bubbles occurring within the lead-glass.”

“When the lead-glass starts to become damaged, the true extent of the fracturing starts to become evident.”
