If diamonds are a girl’s best friend, you’re as lonely as the new kid who picked her nose (and ate it) in the second grade.

But if, as you’ve long suspected, haute cuisine is in fact the secret to true happiness, you’re as peppy as a cheerleader just named prom queen. Or at least you will be, once you get yourself into Opal — upper Queen Anne’s promising new gem of a restaurant.

Coupling a high-concept menu with a casual vibe, the sparkly little spot (helmed by chefs Andrew Leonard and The Rainier Club alum Tyler Anderson) is fittingly semiprecious.

So order up fancy-schmancy entrees (duck breast with foie gras and fiddleheads, cider-braised pork belly with crunchy salsify) and chichi desserts (basil panna cotta, peanut butter and jelly mousse).

The ultra-friendly service, affordable wine list, and handmade chocolates with your check will have you feeling right at home.

And just might make it your new top pick.

Opal, 2 Boston Street, at Queen Anne Avenue North (206-282-0142).
