Is a clarity enhanced diamond a real diamond?

Yes. It is a natural diamond whose internal fractures have been filled to improve how it looks. The treatment is permanent in normal wear but should be disclosed and handled with care during cleaning and repair.

How does a princess cut compare with a round solitaire?

A princess cut is square with pointed corners and a step-like sparkle pattern, while a round brilliant gives more uniform brilliance. Princess cuts usually look larger for the same carat weight.

Will the I1 clarity be visible?

At 3/4 carat, I1 stones can show inclusions to the naked eye, though the clarity enhancement is meant to reduce their visibility. Inspect the stone in person or ask for close-up images before deciding.

Does the yellow gold setting affect the diamond's color?

Yellow gold reflects warm tones into the stone, which can make an I-J diamond look slightly warmer. It also means color differences are less obvious than in white metal.

What should I check on a four-prong princess setting?

Check that all four prongs sit snugly over the corners, since pointed corners chip more easily. Have the setting inspected periodically and avoid knocking the ring against hard surfaces.
