Toughness is similar with sapphire...
Thank you for reply.
crystal break or not......... it is the toughness..
moissanite is single crystal. I know that moissanite crystal toughness is similar with sapphire.
If moissanite crystal toughness is worse, it is very disadvantage.~ I will study more thank you.~~
I also like patina color~ but there is many case which is not good looking (just my opinion)
new crystal material - need help please~
Hello everybody~ I alredy posted about new crystal 3 month ago. moissanite(silicon carbide) crystal glass has very high hardness(60% harder than sappire)---advantage and I have found the graph about transmittance of moissanite crystal. Is there anybody w...
It is also mentioned in your chart that uv light does not pass
Regarding the discoloration due to uv light: we call it patina of the dial and mostly we find patina very attractive. Another aspect of your introcuced glass is the hardness. If you drop a sampphire glass watch, the glass can break. The higher hardness of...

You are right
Zero transmittance means all the wavelenght is absorbed, in this case UV spectrum. The white moissanite is the best one amongst the 3 because the transmittance is stable and oscillates between 60% and 70% inside the visibile spectrum.
graph shows amount of light that gets through
The graph shows the amount of light that gets through the material at the various wavelengths. It seems to show that white moissanite doesn't let any UV light through, but visible light does get through. The other lines are just different materials.
Something to consider is that moissanite double refracts light, as does sapphire.
I don't know the degree of refraction for either, but if moissanite has more pronounced doubling than sapphire, or if the crystal growth doesn't allow for it to be cut at an angle that doesn't show the double refraction, it could be a problem. I'm not a g...
Thank you for advice.~
You are right. moissanite has the double refraction.!! I already check.!! I think moissanite double refraction is not strong, i mean not big different with sapphire. so I think I can use by watch glass- just my opinion.!! Thank you very much for reply.~~
