It's a very pretty ring, but should not be hugely expensive. The diamonds are less than .01 carats each set to give the impression of being much bigger. The gold is good quality, but they didn't use a great deal of it. They don't mention if the ruby is created or natural, but the gemstones are usually the least expensive part. Depending on the price, they either did a good job of making an affordable ring look great, or they are intending to charge more for sentimental value than the materials themselves would warrant. If the price is good, it looks like a great gift for brownie-points purposes. :p
I'm not that into jewelry personally, but I did work in a couple of jewelry stores during summers around college.
