Yes, due to the Sparkling Appearance, it must be real. They're 1 Carat ones, that, as of now, only sell for 100 a piece, so just wait a few more years till it becomes rare. You can also swap a certain Necklace or Bracelet's Gem with that Sapphire.
created sapphires can be bought for 1$ per carat onwards depending upon the size and quality.
Of course it is. It is not really the carat weight but the quality of the stone. And as far as that goes, if it is given and received as a token of love, why should either of those things matter?
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.
Half a carat is .50, and a quarter of a carat is .25, therefore 3/8ths of a carat is .375
This is the deal on gold: 12 carat = 50% 14 carat = 58.33% 18 carat = 75% 22 carat = 91.67% 23 carat = 95.83 ...
