Crystal compositions for the room a house is judged by.
Reading the room first
A living room is usually seen from seated height, from the doorway and from a stair or landing above. A fixture that resolves from only one of those angles looks wrong from the others. Scale is set to the ceiling and the seating plan together: too small reads as an afterthought, too low interrupts the sightline across the room.
Light you can live with
Cut crystal scatters light rather than pooling it, which suits a room used in the evening. Where the fixture hangs over a seating group rather than a table, drop height is set so the crystal sits above eye level from the sofa.
