What makes white star amulets valuable in Path of Exile 2?
Stellar amulets of normal rarity, i.e. those that have no modifiers other than the default “+# to all attributes”, can be converted to Abstract
Stellar Amulet, among the most valuable unique amulets in the entire game, by using a Blinded by chance
on them.
Astramentis is an incredibly powerful item due to its ability to stack an insane amount of attributes (+80-120 to All Attributes). It can be used in conjunction with The hand of wisdom and action
Furtive Wraps, another extremely valuable unique item that increases a character's attack speed and lightning damage based on how much Intelligence and Dexterity they have.
Only “white” star amulets can be used to obtain Astramentis. Blue (magic) or yellow (rare) star amulets cannot be used for this purpose. This is why normal star amulets are worth much more than their more enhanced variants.
You should sell white star amulets or use Orb of Chance
The percent chance of getting an Astramentis is astronomically lowwhich makes single attempts to obtain one via the Orb of Chance method discouraged. Even trying to gamble with 100 Star Charms might not get you an Astramentis, let alone one or two. Of course, there is always a chance of being extremely lucky, but it is unlikely at best.
The decision of whether or not to sell your white star amulets is up to you. Selling one will get you anywhere in between 10-30 exalted spheresdepending on the market rate at the time, or you can try to reach the moon yourself and let fate decide your fortune. It is a high-risk, high-reward game of chance, one that each player must decide for himself.

How to use Orb of Chance to get Astramentis in PoE 2

-
The item is destroyed.
-
The element is updated to a unique one that shares the same base. In the case of the Stellar Amulet, there are only two possible ways it can transform into:
-
Abstract
-
Fixing Yix
-
As the most common unique, Fixation of Yix is the most likely outcome if you fail, a far less desirable outcome than getting Astramentis.
If the bet fails, the Stellar Amulet can—and probably will—be destroyed.
