PRELIMINARY LABORATORY TESTS
The memorial-site being situated in mid-sea, the memorial had to be in granite, and that too of requisite quality, to ensure its long durability.
To select proper varieties of stones, specimen-pieces of granite from quarries in the vicinity of Kanyakumari, were sent to laboratory for ascertaining their quality.
Earlier an examination of the inner core of the Vivekananda Rock was also undertaken by drilling a bore of about 60 feet depth on the top tableland of teh Rock, and sending pieces fo teh inner core to laboratories. The tests gave quite satisfactory results.

QUARRIES
After obtaining results fo scientific tests made on specimenpieces of stones sent to laboratory, two main quarries were selected by the Committee for procuring stones required for the memorial structures.

While the bulk of the stone used in the memorial is blue granite procured from a quarry near Ambasamudram (about 72 miles away from Kanyakumari) in the Tirunelveli district, the red granite used for the Shikharams of the Vivekananda Mandapam has been procured from a quarry near Tuticorin about 96 miles away from Kanyakumari.
