*None of the three gemological reports label this pink sapphire as “color change,” because the sapphire does not show the classic “color change” property of changing color due to different light sources (incandescent/candle light to fluorescent, as would an alexandrite.)
**AGL did NOT state that this is a color change sapphire, but does note that “this gemstone exhibits a color shift. As a result, the color appearance may vary.” And in the color appearance, AGL notes that the color is Pink to Pinkish Orange.
There are certain sapphires that shift in color, not from under different light sources as you might be thinking, but from long term exposure to ultraviolet light. The color of this sapphire is “relaxed” when it is pink. As it is exposed for long continuous periods of ultraviolet light, it will change/shift to a pinkish orange. After a period of time when the sapphire is no longer being exposed to ultraviolet, it will revert back to its relaxed color of pink. Therefore, it has been labeled as a Pink Sapphire on two reports, and “Fancy Sapphire” with AGL.
Q: Is it a Padparadscha?
Pinkish-orange to orangy-pink sapphires are commonly referred to as Padparadscha – the color of a lotus blossom. If this sapphire were that color in its relaxed state, then it may have been considered as such.
Spaulding & Co.
Modernist Gold Bracelet
We like this piece even though it is simply a gold bracelet (no gems), but with obvious artistic flair that commands a sale price of well-over 3 times its high estimated price range. Even without gems, it is a powerful bracelet.
