Quick and Easy Buying Guide

Carat weight: 1 carat = 200 milligrams = 6.5 mm diameter. Doubling weight doesn't double diameter.

Diamond clarity: FL/IF/VVS/VS = super expensive, near perfect. SI = best value if you can check a photo for obvious inclusions (defects).


Color: D-G = colorless, expensive, only if you have money to burn. H-J = best value. Can go lower in gold metal settings than white metal.

Cut: Better cut ratings let more light into a diamond, making it sparkle more. Very important property, don't skimp here.

Set a budget and minimum cut (Premium). Go J color for gold and I/H for white metals. Go searching for SI1/SI2 clarity diamonds at James Allen. Pick a diamond with small/no inclusions. Choose a ring setting and buy it risk-free (60-day returns).

Well, the big news is in - Kate and William are getting married! And the big news on the engagement ring is in as well - they are going to use the exact same engagement ring that Princess Di originally used.

Back in 1981, Princess Di personally selected the oval blue sapphire ring herself. The ring has a central oval blue sapphire which is a massive 12 carats in weight. The central stone is surrounded by 14 diamonds arranged in a cluster. The ring was provided by Garrard of Mayfair.

Apparently it was a difficult decision for William to use it - this is quite understandable given the events in his life.

Interestingly, Harry was the one who originally had the ring - when given the choice to pick items to inherit he chose the ring. But now William and ultimately Kate has ended up with it.
