I read online that god’s throne is made of lapis. And there is suppose to be some connection between Mary and lapis.
I am just wondering where in the bible lapis is mentioned.
Thanks in advance!
I’m a bit late in the discussion, but better to be that…

As mentioned, you should search for instances of the Hebrew word
sappir - usually translated in older Bibles as ‘sapphire’. And as for the divine throne:
And Moses went up, Aaron also, Nadab and Abihu, and seventy of the elders of Israel, and they saw the God of Israel,
and under His feet was as a paved work of the sappir, and as the body of the heavens for clearness. And to those of the sons of Israel who are near He did not stretch His hand; and they saw God, and ate and drank.
And above the expanse that was over their head, as an appearance of a sappir stone, was the likeness of a throne, and on the likeness of the throne a likeness, as the appearance of man upon it from above. And I saw as the colour of electrum, as the appearance of fire within it all around, from the appearance of His waist and upward, and from the appearance of His waist and downward, I have seen as the appearance of fire, and brightness is to it all around. As the appearance of the bow that is in a cloud in a day of rain, so was the appearance of the brightness round about. It was the appearance of the likeness of the glory of YHWH.
