Deekshitulu, 69, has called for a CBI investigation into the case of the missing jewel. He also alleges that since 1996, many such pieces of jewellery have vanished. But this is only a part of his allegations, which have taken a political turn because of the former head priest's perceived proximity to central leaders.
The temple authorities call his allegations motivated because they say he has met with BJP president Amit Shah twice this month, the first time just a day before the May 12 Karnataka election.
He allegedly voiced his allegations in those meetings and later raised them during a press conference in Chennai on May 15. Three days after he went public, he was shown the door.
Deekshitulu has also made serious allegations against Andhra Pradesh Chief Minister Chandrababu Naidu, accusing him of involvement in covering up the vanishing jewellery.
In a press conference on Sunday last, Mr Singhal also fended off the former priest's allegation about the pink diamond, saying what was missing was a ruby that chipped when people flung coins at an idol.
The temple official also said Tirumala was open to publicly displaying all jewellery that belongs to the temple, if the rules allowed it.
