Simple answer is no, not even close. Blue diamonds command values of $100,000 USD per carat and are considered the second most valuable gemstone per carat. Recently a blue diamond was auctioned and sold for $1,349,752 *per carat*. That was a new record in value. I've attached two links below - one to the article about the blue diamond auctioned, and another to a site that sells lab grown blue diamonds. The lab grown blue diamonds are real blue diamonds but not mined, and make an interesting counterpart to your question in that lab grown blue diamonds are less money per carat than a top grade natural sapphire. I am assuming you were really asking about natural vs. natural though.
