What it is

Covington Engineering is a first-party lapidary equipment manufacturer and supplier with an official BigCommerce shop at covington-engineering.com (site schema / branding also uses “Covington Corporation”). The store catalogs Covington-built and Covington-line machines and parts — slab and trim saws, tumblers, grinders and expanding-drum units, flat laps and Maxi Laps, Ameritool grinders/sanders, sphere machines, gem drills, glass lathes/polishers, automatic/vibrating laps — plus blades, wheels, grit/polish/media, adhesives, belts, buffs, and replacement arbors/bearings. It is not a membership gem club and not a week-long residential teaching school.

Who it’s for

Hobbyist and professional lapidaries, jewelers, glass workers, schools, and shops who need manufacturer-direct saws, tumblers, grinders, flat laps, diamond discs/blades, abrasives, and related supplies ordered from covington-engineering.com or arranged during posted Meridian, Idaho office/showroom hours. Contact Us page frames quotes, shipping quotes, pro formas, and order-status inquiries through the site’s admin contact channels during business hours.
