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.

First of all, this show isn't BL, so if you're expecting to get that kind of content here, I am already telling you to back away. I'll go back to this bit of info later on because I think it's kind of important. I actually am pretty much making this review mainly to criticize that issue.

Mixed Feelings
The story wasn't that entertaining, but it was okay. It felt kind of bland, and the pacing was quite slow. Some episodes were enjoyable, but most of them were a bit meh. Most of the time, I didn't feel the connection between the jewelry/gemstone to the story of the owner. Honestly, it made me question sometimes why most of them told their problem to Richard. He's a jeweler and not a detective or a psychiatrist. Also, I feel that most of them could have solved their issues on their own.
I liked seeing the jewelry and the gemstones because they were pretty, but I wasn't ...

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 ...
