5.1CT COLOR CHANGING SAPPHIRE STONE CORUDUM GREEN TO PURPLE GIA CARAT

Description: This stunningly rare 5.1ct Color-Changing Sapphire is a truly precious treasure! Color-changing sapphires are corudum’s chameleons, they can have many different colors however some color variations are far rarer than others. The green color variation is one of those rare colors, while most are blue to purple which doesn’t show much of a color change at all. This specimen changes from a Greenish Blue to a Pinkish Purple with absolutely NO heating! Most stones are heated to increase the quality of the color. For example, unheated Burmese Rubies are far more valuable if they are quality stones due to roughly 80% of Burmese Rubies being heated to get a more vibrant color. When speaking with the owner of the mine in Montana he really conveys the rarity of a stone of this caliber, “This is a one of a kind rare rare rare gem! Clean clean! In 20 years doing this and no one can ever make another like it. The size must be large and clean, two things that make it rare. You see, as they get bigger, they hae a bigger area to have/ host flaws and inclusions.” “This amazing gem is always in a state of change, that said it’s impossible to capture the true life of the gem, as it’s always transforming. It’s truly brilliant in every way!” To back up these statements, we have found no green to blue to pinkish purple sapphires sold thru Christies or Sotheby’s validating this rarity for a color changing sapphire. We will be uploading the entire video of the stone cutting on YouTube along with more in-depth footage of the color changes by end of today and links will be uploaded into the description https://youtu.be/xbgQDdkN2So.

(high quality color changing footage) Color Change Sapphires (from GIA website) Color-change sapphires are corundum’s chameleons—stones that change color under different lighting. Under daylight equivalent (fluorescent or LED daylight-balanced) light, the typical color-change sapphire’s basic color ranges from blue to violet. Under incandescent light, it ranges from violetish purple to strongly reddish purple. Some rare color-change sapphires change from green in daylight to reddish brown in incandescent light. When gem experts judge color-change sapphires, they describe the color change as weak, moderate, or strong. The strength of the stone’s color change is the most important quality factor affecting its value. The color of star corundum has a great effect on its value, though it is understood that miniscule inclusions are the cause of the asterism. They can affect transparency and color, and only very rare, exceptional gems exhibit transparency, depth of color and asterism. As such, the best star corundum has a crisp, distinct star against strongly saturated color. If the color is too light, it doesn’t provide enough contrast for the star’s rays, and the star will be less visible. Star corundum can be red, pink, blue, black, gray, brown, purple, or yellow—practically every color under the sun. The term “star sapphire” encompasses all colors of star corundum except red, which is called star ruby. Naturally, some colors of star corundum are valued more highly than others. In general, the most prized colors are the same as the colors most valued in non-phenomenal corundum: red and blue. Sapphire is one of the Big three of jewelry colored gemstones—the other two are ruby and emerald. A durable stone that’s designated as a birthstone for September, it captures jewelry buyers with its practicality and aura of romance. Corundum is the mineral species that includes both sapphire and ruby as varieties. Red corundum is known as ruby and all other colored corundum (including colorless, or white sapphire as it is known in the trade) is sapphire, although blue is the most well-known.
