Help with timelost Jewels

Guys, title says it all.
Im used to research affixes and itens in https://poe2db.tw/us/

However, in last couple of days I discovered that Jewels like (lots of types of) diamond and other timelost jewels are not listed there (or I could not be able to find it).

Where are you guys researching this affixes and jewels?
There are better places to be informed about game details in deep like this?

THanks in advance!
GG!
