Synthetic diamonds - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

One of today's headlines on RF Cafe is about a company called Apollo, that has discovered a method of using chemical vapor deposition (CVD) to grow a 100% pure diamond from a seed. They are the first to do it in a commercially viable manner.

Do you investment gurus in the audience think this would be a good long-term investment? It seems like an incredible potential for big payoff. ... onds_x.htm

I'd stay away. Some big corp will jump their claim and your money will be wasted. Good idea to watch the progress if you're into diamond trading. It'd be like if someone figured out to to make gold out of lead - the price of the mined stuff would plummet.

BTW, how's my hair? :P

Haven't companies been making synthetic diamonds for 15+ years? Anyway, if these are better and cheaper than the others, the price of diamonds will go through the floor... lose their romantic $$ appeal, and they will be just a cheap gem and a very nice industrial coating.

Greetings kanling:

Yes, industrial grade synthetic diamonds have been around for a long time. Gemological grade diamonds have not been produced in a manner that is anywhere near competitive in cost with mined diamonds (according to the article). Previous methods involved mashing carbon at astronomically high pressures & temperatures, and only produced small samples - usually with many flaws. This new method "grows" perfect (unflawed) diamonds from a seed.

BTW, thanks for your participation in all the forums. Having knowledgeable like yourself people reply to posts is a great service.

Hmmm. Perhaps if the creators of this new synth diamond go with the Cruelty free diamond campaign. They may have a chance. But in all reality I think even that would not help. Ask yourself why have Zircons not become the latest in gem apparel? I can tell ya there are some damn nice Zircons out there and I am sure your avg Joe would not be able to say if it were a diamond or not.
My thinking is that non real diamonds just lack that appeal that a real diamond has. It is not really about the looks of a diamond, it is about the rarity of it, the cost etc...
