Which Gemstones will glow under UV Light?

Ruby, Sapphire, White Spinel, Amber, Peridot, Rhodolite Garnet, small diamonds.
It's a selection of jewelry found metal detecting. Some will glow when a UV light is shined on them. Some of them won't. Which do you think will glow? See which glow in the second half of the video when I switch to the UV light.

Ruby - Bright red glow. The glow of the big solitaire ruby is quite impressive.
Sapphire - Weak red glow, hard to see in the video
Colourless Spinel - no glow
Amber - Weak yellow glow
Peridot - no glow
Rhodolite Garnet - no glow, but a few of the diamonds around it glow
And no glow from the small diamonds in their own ring.

Ruby! I noticed mine glowing when I got my nails done. Screaming magenta.

[loverideone]

You should it put a description on each ring so people like me learn thanks

The first ring is a Spinel and the other ring has 3 small natural rubies.

It's hard to say because there are no other test results to aid in ID, but it could be that the last two are coloured by Chromium due to the bright red fluorescence, so it could be either red spinel or ruby. Do you have any readings from the refractometer? If so, is it one shadow edge or two? (please note, I said "could" earlier because red fluorescence is seen in other gems which may not contain chromium BUT bright red fluorescence is typical of gem materials coloured by chromium)

It depends on which minerals are in the specimen. It's the mineral that reacts to the light

i had the most beautiful ruby maybe it was 7.9 ct. 14kt oval surronding by diamonds i put it back in it's box then one day was cleaning and through out all the boxes. i still cry about losing such a beautiful ring.

[Deadmanshandairbrushing]

Good idea yeah the 2 that glow are rubies but the other looked like onyx and sapphire

[aaronchacon]

What color should diamonds light up? What’s this video showing??

[Elizabeth-vo]

From the left going to the right. One of those diamonds did glow. It's normal. Tho I don't know why some diamonds glow and some don't. But I don't think the big red round ring is Ruby.

[Elizabeth-vo]

But when going right to left I think that the band has 3 ruby's in it.

[hankusuma]

My guess: The 3 stone ring is tanzanite they glow too. The brightest is ruby. Amber should be glow green color, and some of natural diamonds glow too.

[DevilsEnemy-rc]

Some rubies (natural with certificate) can't glow bright under UV light bcos they contain more iron than chromium, usually have darker color (but still have a shining side, on the edge or in the middle)... Synthetic Ruby can glow brighter than the natural one, so this test only for checking a red stone is ruby or not.

[Elizabeth-vo]

I think the bule Marque cut stone is most likely glass.

[Charmegeddon]

So is that ruby far right and garnet second from far right?

[scooterss]

OK the question still is which gemstones glow under UV light.

[Elizabeth-vo]

How in the hell can some of u peeps not see clearly that one ring is Amber??? Btw?

[lovfate]

So which are real and which are fake ones?

[learningp]

so if it doesnt glow its not a real crystal?

[MohammadMostafavi-vg]

Sappire also should react with uv light I believe yours is not sapphire 😂

[tbhsunset]

Just learned we shouldn't to this ot can ruin the stone
