My name is Jessica Ghyvoronsky. I am an appraiser, collector, and founder of JG Antiquary Co., a shop and appraisal practice in Seattle devoted to the study and stewardship of beautiful, storied objects.

I hold degrees in Interdisciplinary Visual Arts and Philosophy from the University of Washington, and a Master’s in Visual Art from Azusa Pacific University. I've completed the Comprehensive Appraisal Studies Program with the Appraiser's Association of America, where I am currently an Associate Member.

My appraisal practice was shaped under the mentorship of Scott Singer of Singer Galleries, a trusted figure in the field for over four decades. There, I was given the kind of education no classroom can teach - the daily handling of rare, precious objects, and the responsibility that comes with them.

Today, I am USPAP-compliant through 2026. I work with private collectors, nonprofits, and institutions alike, offering fine art and personal property appraisals that are equal parts thorough, ethical, and deeply considered.

This shop is my studio, my library, and my rebellion against the disposable. It’s a place where history is held in the hand, where provenance matters, and where beauty and scholarship meet. I truly love this world. If you find yourself here: curious, nostalgic, or simply in need of something meaningful, you are most welcome.
