SELECT segment_name, tablespace_name, blocks, bytes
FROM dba_segments
WHERE segment_name = 'YOUR_INDEX'
AND segment_owner = 'WHO OWNS THE INDEX';

all_segments can replace dba_segments if you dont have access. this tells you how much space in bytes and blocks has been allocated to the segment (index, table, etc...).
