In the quest to sell lighting it has gotten popular to advertise that this “high tech” wonder is daylight equivalent. There is not such man made light source and there will probably never be one made. And even if one was made, what time of the year and hour of the day are you taking as “natural” daylight? Why do I bring this up, because it matters very much to some tourmalines like the one posted.
This larger gemstone is cut with a “super nova” pavilion and a deep three step crown so looking down threw the table you can seem to be swallowed up into its golden heart. And holding this gem under my yellowish light the golden glow is all that I see, but there is a green streak in this tourmaline’s heart. It varies with the “color” of the daylight and that depends on many different environmental factors in addition to the time of day etc. I have discussed.
I hate to call this tourmaline a greenish yellow, because it is so much more interesting. It is so sensitive to the changing quality of the natural light that I feel almost as if you could keep time, like a sun dial, with it. Now almost all yellow tourmalines are prone to getting a greenish cast under some natural lighting conditions, but this gemstone is by far the most sensitive that I have seen. A final point, the yellow green edge varies between people quite a lot, and I am not taking about color blind people, so you may see more or less green.
This deeply cut mostly golden oval weighs 10.33 carats. It has great crystal and appears to be at least eye clean. Its dynamic color shifting, to more or less greenish, depending on the quality of the natural sunlight or artificial light, makes it a fun stone.
