Are my " diamond " tweeters really diamond

Thank you for your thoughtful response...if you send me several bitcoins I believe I have found a way to convert them into something very valuable. Like most speaker designers I have my shop in my garage/manufacturing facility, I am convinced I can make a better speaker then most manufactures...my wife thinks I am crazy, but most people consider me a genius,,,not always stable..

LoL, fair enough

Diamond tweeters by B&W 800 series and Estelon Forza D.  These are the only two models with diamond tweeters I have heard and they sound really good.

Diamond tweeters in my Usher Dancer Mini-2s. I really like them. 

I sincerely doubt they are real natural diamonds. I was in the business of attaching diamonds to stainless steel wire via nickel and copper electroplating for the slicing of silicon wafers for the solar industry. Industrial man-made diamond dust perform and don't cost what one would pay for crushed nature-pressurized 'real' diamonds. The make-up is the same.

I'd bet plenty they are man-made when used in speaker cones or tweeters. Sadly I never heard a B&W diamond tweeter that did not hurt my ears; not sure about Usher as I've liked their earlier models plenty. Give me a silk dome or better yet a sealed film like Raidho or Borresen. To each his own, but needles in my ear are not appealing...
