Since the engagement ring news came out this week sales of similar styled sapphire and diamond rings (albeit much cheaper ones) have soared with online shopping channels and jewelers doing brisk business. The ring originally received by Princess Diana cost £28,000 in 1981, but with todays prices the 18-carat blue sapphire ring is worth an estimated £85,000 - although the one Kate Middleton now has that belonged to Diana is priceless. One things for certain despite differing opinions on current valuations, that jewelers are going to have a lot more requests for blue sapphire, thought to symbolize mental clarity and devotion, engagement rings.
