I have yet to find an English word, or in any language, which translates to someone who appreciates the beauty in all things.
a person who has or professes to have refined sensitivity toward the beauties of art or nature.
an expert judge in matters of taste.
He was a connoisseur of life, appreciating the trivial, minute and even mundane things that others would normally overlook.
an aesthetic personality will appreciate beauty wherever it can be found.
aesthetic (adj) - "characterized by a heightened sensitivity to beauty" e.g. the poet and his aesthetic friends.
But if you are looking for a word describing someone who finds everything beautiful, someone who sees beauty and finds good in everything, you could say they are a Pollyanna, after the character in the novel by Eleanor H. Porter (1868-1920)
