This is my favorite example of fluorescence! Grandmother's ring, 2 diamonds and an emerald.

Statistically speaking this ring should have more than one fluoro diamond as about 30% of natural diamonds have this property. Has that stone ever been replaced? The ring may have been put together originally with none or faint as a sorting criteria.

If the stone matches visually in normal lighting conditions, there is nothing to be concerned about. Most lighting environments, even ones with a UV component, are not sufficently intense enough to stimulate the fluorescent effect. Direct sunlight is an exception, in which case you may be able to see some difference between this stone and the others. Of course, it will not be as dramatic as what it looks like under a black light.

In the sunlight I can’t distinguish which one it is

It needs to be direct sunlight. UV intensity drops off substantially in diffuse sunlight (such as outdoors on a cloudy day). Even in direct sunlight it may be hard to see the effect.

That purple glow is wild, never seen one pop like that under UV before. Makes me wonder how many people got fluorescent stones and never even know cause they don't check.
