What it is

Jerry’s Rock and Gem is a lapidary equipment and rockhound supply store at 804 West Valley Hwy, Kent, Washington 98032, south of Seattle. Its About Us page calls it “a gigantic lapidary and rock/fossil hound supply store.” The business started in 1954 as Jerry’s Agate Shop, named after machinist Jerry Appleton, and moved to its current location in 1962. The current owner, Glen, a G.I.A.-trained gem dealer, bought it in 1990. The home page says: “We carry a complete line of Tumblers, Grits, Rock Saws and Grinders, as well as Lapidary Supplies.”

The store sells through its own WooCommerce cart (https://jerrysrockandgem.com/cart/), with Add to cart buttons and printed prices. Its online departments include Saws, Cabbing Arbors, Tumblers and Abrasives, Rockhounding Supplies, Prospecting Supplies, Rough Rock, Books, Fossils, Meteorites and Mineral Specimens. The About page also says the store’s inventory is “much more than what we could list on this site.”

Several cabbing arbors and saw packages (8-ST4, 6-6ST, 6-4ST, TS6, FS8-C) are labeled “Temporarily out of production” while still showing prices. The TS6 package was listed at $450.00 and out of production; the TS10-C package was also listed. Don’t count on these.
A Covington 6-inch trim saw and a Covington 10-inch trim saw with vise were not on the official Saws category page on this check, and guessed product URLs for those models returned HTTP 404, so those prices are not cited.
The site doesn’t name the maker of the tumblers and arbors. It names Covington for the saws only. Tumbler brand: UNVERIFIED.
Some items (the grit kit, some fossils, moldavite) have no online price. Call for those.
Returns: the Return Policy page says “All Sales Are Final.” Online equipment ships in the original packaging with the manufacturer’s warranty, and the store will consider a return at its discretion with proof of purchase.
The site gives two founding years: the home page says “since 1956”, while the About Us page says the business started in 1954 and moved to its current location in 1962. This listing follows the About Us page.
Not affiliated with Lapidary Plaza. Nothing was added to a cart or bought, and no email, phone call or form was used.
