Silmaril ID

Fëanor, the Elven King, great and most gifted... at the end of all renowned works of the elves, he made the Three Silmarils of a substance devised by and known only to himself... and as three great jewels they were in form, like the crystal of diamonds they appeared... the inner fire of the Silmarils Fëanor made of the blended light of the two trees of Valinor, gold Laurelin and silver Telperion... the Silmarilli of their own radiance shone like the stars of Varda; and yet, as were they indeed living things, they rejoiced in light, received it and gave it back in hues more marvelous than before... the very memory of their radiance was a gnawing desire in the hearts of many who set eyes upon them... (from Silmarillion by J.R.R.Tolkien)
