How strong are Karna Divine’s armour and earrings?

Lord krishna about Karna’s armour –
Drona Parv, Section-15
Had he possessed the armour and had he possessed the earrings, the powerful Karna would have been able to defeat everyone in the three worlds, even the immortals. Vasava, Kubera, Varuna, lord of the waters, and Yama would not have ventured against Karna in an encounter.
Had that bull among men possessed those, you with your Gandiva and I with my sudarshana chakra would not have had the capacity to defeat him in a battle. It is for your welfare that Shakra used delusion to rob him of his earrings.
Drona Parv, Section-15
According to lord krishna, all immortals were incapable to withstand valiant karna donned in divine armour-rings
According to lord krishna, his sudarshana which was equal to trident of shiva was incapable to penetrate divine armour of karna
According to lord krishna, arjuna was incapable to penetrate divine armour of karna (thus all weapons of arjuna including brahmasira astra and pashupata astra were incapable to give small scratch to divine armour of karna)
Why all weapons including narayana astra, pashupata astra and brahma astra were incapable to give small scratch to divine armour of karna?

‘Surya replied, “O queen! O one who has been excited! O timid one! Aditi herself gave me these earrings. I will give them to him, together with this excellent armour.”
‘Pritha said, “O illustrious god! O god! O lord of the cows! If my son is going to be as you have said, I will happily unite with you.”’
Divine armour and ear-rings of karna were originated from nectar (amrita)
