The Case Files of Jeweler Richard (Light Novel) Vol. 4

This highly acclaimed mystery tale about a young man teaming up with a handsome jewelry appraiser inspired a popular anime–and a manga adaptation (also from Seven Seas)!
When Seigi Nakata rescued a handsome young jewelry appraiser from a group of drunken assailants, he got more than he bargained for! The appraiser is Richard Ranasinghe de Vulpian, a brilliant and mysterious British jewelry expert. Seigi hires him to appraise a family heirloom...and that is just the beginning. Together, they unlock the secret messages hidden in the hearts of precious stones–and those who possess them.
