Use pattern on the walls or in the curtains. Skirt the table. I like a distance of 36 inches between the bottom of the fixture and top of the table. Perhaps the one you have is too heavy or ornate for the glass-top table. Be sure that the chandelier is no more than one-half the width of the table.
Most people pick chandeliers that are too small.
A good rule is to hang it 30 inches off the table top, or 60 inches off the floor, since tables are 30 inches high. The new larger chandelier that you bought to replace the builder's chandelier needs some visual weight under it, which the glass-top does not afford. I would try a beautiful tablecloth, trimmed at the bottom, going all the way to the floor, along with a good-size centerpiece. When eating at this table, you can use another smaller table cloth over the dressier one for looks as well as practicality. Transitional or contemporary tables are generally heavier and bulkier than Hepplewhite or Sheraton ones, so keep style in mind when you are shopping.
