Is the Stylecraft Marquette 11 big enough for a dining room?

No. At 11 inches wide it is a mini chandelier. Use it over a small table, in a foyer or powder room, or hang two over an island. A full dining table needs a wider fixture.

Does it come with bulbs?

No. It has three sockets and takes LED bulbs, which you buy separately. Check the socket type and wattage limit on the fixture label before buying bulbs.

How much assembly is required?

Expect to attach the crystal strands yourself. That is normal for crystal chandeliers and takes time, so plan for it before hanging.

Will it fit an 8-foot ceiling?

The fixture is 25 inches tall before any chain or rod. On a standard 8-foot ceiling that leaves little clearance, so it suits high ceilings or open stairwells better.

What finish and materials does it use?

Polished gold steel with crystal glass. The gold is shiny, so it shows fingerprints and dust more than brushed finishes.

Dimmability depends on the bulbs and your wall switch, not the fixture alone. Use dimmable LED bulbs and a compatible dimmer if you want to lower the light.
