Someone must have said something to this Etsy seller, because his ad now features this "About Diamonds" section:
One of the questions I'm asked repeatedly is whether the blue center diamonds featured in some of my items are authentic. The short answer is and emphatic YES. All of my diamonds are 100% natural mined diamonds. Nevertheless, naturally occurring coloration is very rare with intense blue being one of the rarest varieties as it is the case with the world-renown "heart of the sea" diamond featured in the movie TITANIC. Due to their extremely rare nature, natural blue diamonds can fetch OVER ONE MILLION DOLLARS (USD 1,000,000.00) PER 1.00 CARAT at auction! Notwithstanding, technology offers a less expensive alternative way to turn natural diamonds to the beautiful blue color that you see in my items.
This coloration process is not only avant-garde and difficult but is also GUARANTEED TO BE PERMANENT.
Well, is that not a relief -- to know that he guarantees that the fake blue of the diamond is permanent, so that we know he didn't just get an ordinary white diamond and draw on it with a bright aqua blue sharpie?
Gosh, now that I think about it... David doesn't guarantee that the color of his
diamonds will be PERMANENT.
Should we be worried?
