Produce symmetrical pear-shaped collets, uniform tapered bezels, and distortion-free mounting settings with the authentic O.M.O® Italy Teardrop Bezel Forming Block and Punch Set (Model 8/D). Manufactured in Italy from high-grade hardened tool steel, this heavy-duty forming die set is engineered specifically for master goldsmiths, diamond setters, bench jewelers, and fine jewelry manufacturing workshops.
Featuring 11 precision-machined teardrop (pear) cavities spanning 4 mm through 14 mm paired with a matching 17° tapered teardrop forming punch, the Model 8/D converts flat, soldered precious metal bands into true-angled stone settings in a single pressing or mallet operation. The 17° wall taper matches standard faceted gemstone pavilions and tapered cabochon profiles, ensuring stones rest securely without rocking or gapping. Built to form ductile precious metal sheet stock—such as yellow gold, white gold, fine silver, copper, and brass—up to 20 gauge (approx. 0.81 mm) thickness without galling or wall buckling, the block features clearly stamped millimeter size markings for rapid bench selection.
Key Features & Benefits
-
Standard 17° Gemstone Pavilion Taper: Precision-ground 17° angle on both the block cavities and matching punch creates consistent, tapered bezel and collet walls that fit standard pear-cut stones.
-
11-Hole Graduated Size Range (4 mm – 14 mm): Covers 11 sequential millimeter increments (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, and 14 mm) to accommodate accent drops through large solitaire center stones.
-
Hardened High-Grade Italian Tool Steel: Heat-treated steel construction resists surface denting, cavity deformation, and edge wear under repeated mallet blows or arbor press force.
-
Forms Sheet Stock Up to 20 Gauge (0.81 mm): Engineered to shape substantial bezel strips and heavy gallery collets in gold, silver, platinum, copper, and brass without splitting seams.
-
Stamped Millimeter Identification: Each teardrop cavity is stamped directly onto the top face of the steel block alongside the
8/DandMADE IN ITALYhallmarks for instant sizing. -
Smooth Cavity Finish: Ground internal walls minimize friction and surface marring on annealed precious metals, reducing post-forming filing and polishing steps.
