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.
