Q.Diamonds can now be made in laboratories by Scientists???

A.If it should ever come to that, diamond lenses would become the lightest and highest index lens material. The would impervious to scratching. The biggest drawback would be the design and application of a decent antireflection coating. Without a coating, reflectivity at each surface would be about 17%. Chromatic aberration might be a problem. Even so, based upon posts here, people will be complaining about thick lenses and want lighter ones as well. A lot of people who want diamonds for jewelry want them because they're expensive, not because they're just diamonds. All De Beers has to do is keep pumping the idea that their diamonds are what the consumers want and artificial diamonds are fake, regardless of whether they're indistinguishable. De Beers already has methods of tracking the authenticity of their diamonds, so whether you can't tell them apart is really irrelevant in that respect. Diamonds for industrial purposes is another thing, but there already De Beers doesn't have a lock on that market.
