Thinks for a minute. He looks at the gemstone necklace thinking of clarity, body and flaws. Like a good ruby wine, the hotel did serve a good one earlier. He has an inspiration to test investigate an idea.
"Look we are in a studio. Lights, camera,
action. By accident we may have stumbled across a great place."
He hurries to the studio and begins to check out the overhead studio lights, stripping one from its' socket and turning the power on. He looks about for lens and magnifying equipment.
"Why don't we see if your corundum has any conundrums?
You do know that sapphires can be laboratory grown and created by artificial means, not just natural minerals mined from the depths.
Your necklace may be lab grown with a specific reason in mind."
Tibbs wants to create a fine beam of light and shine it through the sapphire to see how refractive the light through it is. Certain sapphires will change colour under extreme Celsius heat, others reveal interior impurities and mineral deposits. The light refracts because the speed of light differs travelling through the prism. Minute etchings on the facets, only visible under microscope can also be magnified and viewed by the light beam refracting out the gem onto a surface.
"Think of looking at a rainbow trout in a river. You view the fish but because of the refraction of light in the water, you view the fish at a depth and distance fractionally away from its true location. The fish on the other hand from within the water views the angler in more magnifed detail.
So this necklace may be wrapped up in Saffa's FTL theories and its inner secrets revealed by differences in the speed of light being passed through it."
It might take a while to do an adhoc experiment to get the right fine tuned light beam to focus on the necklace sapphires and record the results. Hoping it reveals something more than a kaleidoscope of colours.
