Assalamu aleykum,
Some precious stones such as rubies, pearls and coral are mentioned in the Qur’an:
“(In beauty) they are like rubies and coral” [al-Rahmaan 55:58]
“Out of them both come out pearl and coral” [al-Rahmaan 55:22]
“Like unto preserved pearls” [al-Waaqi’ah 56:23]
And they have been mentioned in many traditions as well; most of the times the stones are mentioned to be set in rings.
Assalamu aleykum,
Concerning the wudhu and the correct steps, I suggest you to read the book Ritual and Spiritual Purity by Sayyid Muhammad Rizvi, in the chapter about purity he gives all details related to wudhu, its importance and the correct way to perform it:

And also this interesting article by Sheikh Saleem Bhimji:
I am a Malawian muslim boy aged 21 and single. My family is poor. I am studying at Lilongwe University of Agriculture and Natural Resources. But my family being poor does not support me efficiently. The university does not feed us nor accommodate us freely, we students have to pay for their services. So I ask this question because I want to invest my little money to a certain web org, called Automated Web Services (AWS). I would like to know if it is halal to get involved? If you want more information abou this AWS visit www.awsmining.com
Assalamu aleykum,

Assalamu aleykum,
Istikhara is never required. One can decide to perform it, but since it is not an obligation, the answer to your question is no.
Please have a look at an interesting lecture about Istikhara in general:

Hope this helps out understanding the matter inshaAllah.
