Is it typical for tennis bracelets to display fluorescence in nearly all stones? They look bright and sparkly outside. My light doesn't fully cover the bracelet's length, hence the two pictures with UV lighting.
I love that a few stones have fluorescence. It can be handy (but not infallable) when assessing if diamonds are mined or created in a lab. My jewelry has them like that too. Lovely bracelet.
Firstly, this proves your bracelet is natural.
Secondly, the cheap UV torches (390-405nm) create a much stronger blue fluorescence effect than the traditional UV (365nm) lamps. So this is about right. Expect to see about a third light up and maybe more because of the UV difference making some Very Very Faint glow.
When looking in daylight use shaded daylight as in direct sunlight the best cut stones will appear darker.
What you may see is the stronger blue fluoro stones appear whiter and a tiny bit brighter (unless they have clouds or internal graining - then they will appear a little dull in daylight).
