Luminescence test success!

[Elizabethhunts]

Tomorrow im some in to the jewler for appraisal, and for examination.really interested to see what he tells me about these beads?

need subtitles to appreciate what's going on here.

What’s so successful about this? I’m curious.

 

[Roselina]

Hi there! Could you explain what you do?

I guess glowing rocks? I was told that was a good thing!

Do you mean fluorescence in UV light? This would look different.

 

[stonehunter20]

which one is glowing? all i see is purple purple purple!

Hi Elizabeth, to test gems for their UV fluorescence you need the correct UV light wave length.
Then you need to understand what glowing or not glowing and what colour the “glow” is to help identify the gem.
Identifying gems is usually a multi step process with different types of tests to help confirm identity.
For example, you don’t want a piece of green jade with fluorescence because that’s a strong indication of being dyed!
This is the type of UV penlight you can buy online. Best used in a darkened room.

Is using a stronger light going to affect the outcome? Im using a 600, and wondered if i would have any luck, and i did! Its very hard to hold the camera and the light. Hopefully I can capture at least one good photo. My phone died mid act. BLAH

 

[Elizabethhunts]

Gosh
How is phospheresence tested?

 

[Elizabethhunts]

The beads glow more than anything else in the bunch. How strange. Is glowing pink abnormal?

I suspect 600 is not "strength" of light but wavelength.
Different gemstones fluoresce under different wavelengths, as @Bron357 was explaining.
The wavelength you want (what GIA uses for diamonds) is 365nm.

6000nm would be orange so maybe 600 is a model #?
What I find interesting is how reactive parts of the cloth they are on is to uv.
My guess is its the low cost 380-390nm leds in the light.
99% of them are.

I'm confused. What is OP try to prove??

That the stones/pieces could be of value, as in real diamonds and gemstones being mis-sold as costume jewellery that the OP had purchased.

That's my understanding from another thread.

I knew that... Just wanna hear it from OP.

fixing typo

 

[Rfisher]

It looks like plant growing lights were used?

 

[AprilBaby]

That proves you have blue And purple light...

 

[PintoBean]

Does it matter if it's UV-A, UV-B, or UV-C?

So what did the jeweler say?
