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.
Blue screen is a method of closing trade deals such as commodities. In this business, lots of people try to use your banking information and purchase the item you want or obtain a line of credit. Blue screen allows the buyer and the seller to view the other's information. The seller shows his proof of the item (which is usually worth a lot of money and secured in a bank) while the buyer shows his proof of money. It is just a more secure way to gather this information with blue screen. A log in and pin number is needed to complete this transaction.
money acts as a factor of production. it is because the other factors of production are indirectly dependent on money. more the money paid to any factor of production more it will work. hence money encourages other factors of production to work more.

It is true that rubies, sapphires, and emeralds are more rare than diamonds. The reason is that the elements which make up rubies, sapphires, and emeralds which give them their color are more rare in the environment than carbon which is what diamonds are made of.
Sapphires come in a variety of colors and the more intense the color the more valuable the stone, however, blue is the color associated with sapphires. The most valued blue sapphires are velvety blue to violetish blue in medium-to-medium dark tones.

Blue diamonds are speculated to be rarer than white/clear diamonds because it is more difficult to form naturally. Blue diamonds, as such, are worth more than regular white diamonds
Diamonds are becoming the common choice in engagement rings. They say the bigger the diamond the more you love. Other than diamonds, other gemstones such as rubies, emeralds and sapphires are used in rings as well.
No. Pink diamonds are little more but they are both more expensive then colorless diamonds.
Because these two gems are different minerals and are valued differently, your question is akin to the question -- which is more expensive: apples or oranges? Generally, the highest quality diamond of the same carat weight as the highest quality sapphire, the diamond will be more expensive. However, this statement is not always true.
Diamonds are the hardest mineral/gem in the world but they are brittle. The next step down from diamonds are sapphires and rubies. They arent brittle and are quite hard. On a scale of 1 to 10, diamonds (#10) being the hardest, sapphires rank 9. For more on the scale I used. Google MOHs scale of hardness
Blue diamonds are extremely rare, more rare than even pink diamonds. As with anything that is rare and well coveted its definitely going to be more expensive.
