Exposing jewelry to direct sunlight can cause discoloration and dullness. Ultra-violet light can also lead to structural problems with your piece, leading to fast deterioration. Heat can also distort color in some gemstones. It is thus advised that you store your jewelry in a cool dry place.
Does a UV lamp damage diamonds?
So, what happens when you expose a diamond to UV light? They exhibit visible light, usually in the color blue – something known as fluorescence. And yes, UV light can technically destroy the surface layers of a diamond, too. The process of atom destruction is extremely slow, but the damage is still there.
Is it safe to put metal under a UV light?
Metals are almost entirely unaffected by UV because of the availability of free electrons to absorb photon energy without undergoing energy transitions or bond dissociation.
Can diamond ring go under UV light?
If you’re shopping for a natural diamond you’ve most likely learned that 25 – 25% of natural diamonds fluoresce i.e glow blue under UV light and when you go outside.
Why does my diamond turn blue under UV light?

Does UV light destroy plastic?
All types of UV can cause a photochemical effect within the polymer structure, which can lead to degradation of some sort to the material. The higher energy UVC is the type most likely to affect plastics. Absorbed UV energy can excite the photons in a plastic. … Those free radicals can cause breaks in the polymer bonds.
What does UV do to rubber?
This damage, called UV degradation, affects many natural and synthetic polymers including some rubbers, neoprene and polyvinyl chloride (PVC). With too much exposure, these materials can: Fade color. Lose strength.
What stones glow under UV light?
The most common minerals and rocks that glow under UV light are fluorite, calcite, aragonite, opal, apatite, chalcedony, corundum (ruby and sapphire), scheelite, selenite, smithsonite, sphalerite, sodalite. Some of them can glow a particular color, but others can be in a rainbow of possible hues.
What do fake diamonds look like under UV light?
Fake diamonds may stay fogged for 2 seconds or longer according to National Jeweler’s Supply. … Ultraviolet Light: About 30% of diamonds will glow blue under ultraviolet lights such as black light. Fake diamonds, on the other hand, will glow other colors or not at all.
Why are my diamonds turning green?
Natural green colour is the result of radiation damaging the diamond. This can occur when the diamond is still in the volcanic pipe (kimberlite) that brought it to the surface, or even if it has been eroded out from there and found in a river / alluvial deposit.
Do fake diamonds glow in the dark?
Diamonds are expensive because they’re beautiful and rare. But fake diamonds often sell for a lot of money, too. … The famous Hope Diamond looks blue under normal light (above), but it glows bright red (below) after being exposed to ultraviolet light.
