What it is

Lasco Diamond Products is a manufacturer of diamond burs and diamond tools in Chatsworth, California, with its own online store for its art, lapidary and industrial line. Its home page says “Lasco has been manufacturing quality diamond instruments in the USA since 1963” and that it serves “the dental, art, lapidary, glass, industrial, hobby, and cosmetology industries.” The art and lapidary site says its burs work on “Precious and Semi Precious Gems, all types of Stone, Glass, Metal” and more, and fit popular rotary tools such as Dremel and Foredom as well as dental-style micromotors.

This listing covers the art, lapidary and industrial store, not Lasco’s dental or manicure lines.

Who it’s for

Stone carvers, cabochon cutters who want fancy shapes, opal and fire agate carvers, bead drillers and faceters who need diamond burs, wire drills, core drills, small saw blades or diamond polishing powder and compound.

Why it’s listed

It’s a first-party manufacturer with its own cart and posted prices (not a marketplace reseller). Lapidary classes name it directly: the Palomar Gem & Mineral Club’s classes page tells carving students to buy replacement burs from LASCO Diamond. It is Lapidary Plaza’s first Chatsworth supplier.

Notes

Carving sets (store, check date): 21 Piece Opal & Fire Agate Carving Set $125.00 (7 bur shapes, each in 150, 400 and 600 grit; the page lists a retail value of $174.50). Starter Kit $59.00 (12 pieces, 150 grit).
Individual burs (store, check date): B20 3/32” shank ball bur $7.25 (100–600 grit) and CC250 carving diamond bur $9.00 (80–600 grit).
Drills (store, check date): 1mm Small Diamond Drill, 10 pack, $18.50. The small drills page also sells a 12-piece assorted drill set (0.75–2.5 mm) and 100-piece bulk packs. Diamond core drills run from 1/16” to 5/8”, and the page notes the larger sizes need a drill press.
Polishing (store, check date): faceting-grade, resin-bond diamond powder in 5-carat vials, from 100 to 100,000 grit (e.g. 1,200 grit $8.75), and premixed diamond compound in 5-gram syringes (e.g. 1,200 grit $18.00). The powder page explains how to mix your own paste with oil, petroleum jelly or beeswax.
Carving machine (store, check date): the Micro Ultra Machine was listed at $299.00 (list $399.00) but marked sold out. The older Micro Delux machine is out of production, though Lasco says it can still repair many existing units.
Ordering (home and art site): order online, by phone or by fax. The art site says orders generally ship within 24 hours.
Small source inconsistency: the Micro Ultra store page says the machine includes a foot control, while the machine information page calls the variable speed foot control optional (and the store sells it separately as ULTRA-FOOTCTL).
Not affiliated with Lapidary Plaza. Nothing was bought, and no email, phone call or form was used.
