Оригінальний текст - Французька - Je suis heureux car je sais que tu as ...

Hi Elamer Neto. I can't accept the second sentence as it is, the form from verb "to be" is here at present of indicative, second person singular ("tu", so it absolutely needs the proper pronoun before the verb. Then, for the whole text to be correct, you've also got to switch the "vous" from the first sentence with a "tu". So it will give :

"Je suis heureux car je sais que tu as vu. Tu es une perle précieuse dans une mer de tant de beauté."

I'll do this for you as I won't be connected for a while. This way your text won't wait too long in stand-by before being translated.

Have a nice day, best regards,
