While it may not be the true Holy Grail, an international congress held November 7-9, 2008 at the Catholic University of Valencia, Spain declared that the artifact "has tremendous cultural value due to its impact on history and literature."

Presenters at the conference traced the origins and history of the relic which dates its move from Rome to Spain at 258 C.E. The cup is crafted by red agate with a jeweled frame added in the 13th or 14th centuries. Miguel Navarro, doctor in church history from Rome’s Gregorian University, said that the chalice "insofar as relic, is beyond and above science, because its primordial significance belongs to the realm of faith, which does not mean that we approach it in an anti-scientific or fundamentalist way." Rather, "we have the obligation to study it scientifically in its materiality."
