It should be observed that NO sapphires of any shade should have already been afflicted by any kind of temperature treatment as their strength becomes completely ruined in the process. The quality must certanly be “attention clean”, meaning little to be seen within the gemstone but small bits of “silk”, or rutile, and shade saturation will establish how potent the gem may be.
The higher the saturation and range of shade the stronger the jewel, but NOTE, if the saturation becomes too much it will affect the clarity and hence begin to reduce both efficiency and value. The jewel must be a nice gem or “glass-like” and you ought to quickly see into it, or even simply with the bare attention certainly below magnification.
The issue that today arises today is that newer operations of heat therapy have now been discovered and mastered which make a much better looking final product. Today’s temperature treatments are almost 100% diffusion temperature treatments for not only ruby, but all sapphires as well. This really is achieved by finish the gem crystal with a melted crystalline material that archero hack “dissipate” the required shade deep into the gemstone. That makes a low quality rather beaten up shade become serious and lively when finished. As iron oxide is what’s in ruby that produces the red color, the very first diffusion remedies coated the gem with iron oxide and then under enormous conditions it “burned” the greater red colorization into the ruby.
Today recently temperatures hotter than actually used before are used to actually melt the species of gem “chrysoberyl” (which provides the sought following varieties of “chrysoberyl cats-eye” and “alexandrite”) and this dissolved chrysoberyl is used to coat the ruby or sapphire to improve its color. Such gems are useless for jyotish purposes and their energy will soon be “dead “.Unfortunately for all of us, as the deal is acknowledging that newer treatment (for they are in the business of offering treasures for his or her splendor and not astrological reasons) creating a prettier and less costly item makes them less expensive because of their customers. This is specially therefore in the depressed financial weather of today.
Worse would be the glass-filled varieties that use dissolved glass to actually load significant breaks within ruby. These therapies are getting more and more common to ensure that truly normal sapphires with no temperature therapy whatsoever as well as only the conventional heating that has been used formerly for ruby are now actually rapidly becoming scarcer and scarcer to find. There are a few reliable gem merchants that offer in normal, unheated sapphire and gives qualification with each purchase of such, but avoid such a thing inexpensive in price.
Fine rocks can not be “cheap” whatever the case, nevertheless the motto “when it looks too excellent to be correct it always is” will be a fact when discussing precious gems. If you don’t have the very best of associates in the gem trade and can find some body with the strange natural ruby or a very few left from old inventory, they are nearly impossible to find anymore.
