Likely broad spectrum LED light directly overhead, yes. Similar effect to sunlight.
Thank you!! I have been wondering about this for almost a year. Thanks again!

My diamond looks dark in sunlight
If you look at a diamond in direct sunlight then the better and brighter the cut - the darker the diamond will appear.
I took these photos on a hot 30°C cloudless day in front of my Canterbury store.
The first photo shows 5 different cut styles in direct sunlight. You will note the ideal-cut round on the right appears darkest (the blue hue is from the sky, the dark areas are reflections from the black phone).
Note that the only a few bright flashes in the ideal-cut round but there are twice as many in the marquise in the center ring. Yet in real life the round is quite a bit brighter than the marquise.
In the photo below I moved the stones into the shade of my body; note the round ideal-cut is now the brightest!
The better the cut the darker a diamond will appear in sunlight.
So if you think your diamond looks dark in direct sunlight – do not worry, it is a sign that the cut is really good.
If you want to look at diamonds out-doors then shade the direct sunlight. Or better still, wait for a cloudy day and find a leafy tree that has thousands of tiny point light sources and then you will be amazed at the combined brightness and firey coloured sparkles!
So my whole ring doesn't go dark, just one area on the top gets a dark grey half moon when tilted at a certain angle.
It's visible only from that angle. Is that something similar to the issue here? If not what can it be? It drives me nuts.
That is a leakage area I think. if you hold a torch or light behind that area and it lights up - then it is leakage.
Thank you @Garry H (Cut Nut) I will have to try it.
I only see it from that exact angle, if I tilt it slightly then the dark area disappears. Is that common with leakage?
