The one I just bought my wife is a KJV, it has gold leaf on the edge of each page and on certain large capital letters that start new verses etc. The quality of the paper is superb, and you feel it when you touch the pages, but you also know that this Bible is more fragile, so you hold it more carefully and are very aware to not damage it, like holding a baby.
Those are some of the higher end things about it that aren't necessary, but you just feel the love and attention someone put into delivering the words of God. What is a nice feature for even the cheapest of Bibles is when they highlight the words of Jesus in red or some other color so that they stand out. It just makes you focus on the words more when you have a constant reminder of the elevated importance of those words.
