Local jewelry repair / stone supply and reset

Seeking advice on how to find a skilled jeweler in the area of Bethesda MD. Gold band has lost one of its tiny diamonds and I’m looking for someone who can supply and set a new one. The band is not plain, but has a cross-over organic pattern (uneven rather than smooth surface). The few stones are flush set.

Any advice in where to search for a repair jeweler? Word of mouth recommendations welcome.

Thank you!

p.s. I haven’t visited Ganoksin for a few years, since the site update, so I hope I’m placing this question in the right discussion.
