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).

Katy Perry Engagement Ring

Katy Perry burst onto the international music scene with her controversial but wildly popular hit song, "I Kissed a Girl" in 2008. After a string of hits, she is now established as one of the biggest pop stars in the world. At the same time as her success was blossoming, she met the British comedian Russell Brand, and they started dating in 2009.

Brand proposed to Katy in India in 2009. He gave her a relatively rare pink diamond of about 5 carats, set in a Cartier ring. Apparently, that wasn't quite to her tastes, so she swapped it and ended up with another ring with a slightly smaller diamond. However, a designer named Hanut Singh also claimed he help Brand find a design to give to Katy.
