A three stone engagement ring with sapphires is a wonderful twist on the three stone style which typically depicts the past, present, and future of a relationship. The center stone is a diamond and since it is quite different from the blue sapphire side stones, it appears to put more emphasis on the "present" state of your relationship and the glory of the love the two of you share is expressed through the dazzling brilliance of the center diamond. The blue sapphire side stones therefore depict the underlying themes of your relationship that are ever present such as sentiments of friendship, loyalty, and virtue.
