Possessing a deep knowledge of mineralogy, Richard Ranashinha de Vulpian is a young and handsome British jewelry appraiser who owns a small shop in Japan. One fateful night, Seigi Nakata, a righteous college student, saves him from drunks who were harassing him due to his good looks. Upon learning of Richard's identity, Seigi hires him to appraise a pink sapphire ring that was left behind by his deceased grandmother.

Before long, Seigi becomes a trusted part-timer at Richard's shop. Together, the duo solve various jewel-related requests from diverse clients of different backgrounds. Step by step, they unravel the hidden motives and feelings that lie within the gems in order to understand and empathize with the little stories behind each piece of jewelry.

To which, it ...

On the other hand, it doesn't really seem to have many redeeming qualities that make it worth watching. The story was good for the most part. I enjoyed the representation of many different types of people with their own types of problems and the gem lore. But I never felt like the side characters were more than just their surface problems and identities. design-wise none of them really stood out to me. I can't see ...

This was almost painful to watch.
While the premise of the series was actually kind of interesting, the story and characters were handled very poorly and the series was overall a great disappointment.

Plot: I feel like its a bit of a reach to say this show is a “Mystery” when most of the mysteries they encountered felt like family therapy sessions and were solved by the characters just speaking together.

After a while the plot suddenly takes on a more dramatic route involving crazy family drama and a bunch of very stereotypical “I’ll disappear from your life forever and its better this way” lines, but ...
