One of my favorite quotes from The Little Prince: "It is only with the heart that one can see rightly; what is essential is invisible to the eye." The dots for the words "heart" and "essential" are done in 24 gold keum boo, with the rest of the piece being sterling silver.
This piece is in accurate, grade 2, contracted braille. All of the spacing and dot size is according to NFB standards to be correct and legible to tactile readers.
Because braille is contracted, this piece may not have the number of cells (letters) you expect. Letter combinations such as "the" and "er" are covered by a single braille cell.
