While presenting this ring, TD urged viewers to go to any jeweller and compare the price for this ring, carat weight for carat weight etc. Personally I don't you'll be able to do that because I really don't think you'll find a comparable ring. Do you think any reputable jeweller would set this stone in a stingy, measly 2.13g of gold? Ludicrous!
