Hold faceted gems, round diamonds, and cylindrical watch components in true axial alignment without tilting or slippage. Manufactured in Switzerland to exacting gemological and watchmaking standards, the Regine® Stainless Steel Diamond Tweezers with Grooves (16 cm) feature an engineered internal groove running through diamond-coated serrated jaws.
This longitudinal guide channel seats round diamond girdles, faceted gemstone rims, watch stems, and delicate pivot pins directly along the tweezer’s center axis, eliminating side-roll and drop risks. The exterior features an anti-glare satin finish that diffuses intense illumination from gemological microscopes and bench lamps. Crafted from resilient, corrosion-resistant spring-tempered stainless steel with milled finger grip serrations, this line is available in four dedicated tip profiles: F1 (Fine), M1 (Medium), L1 (Large), and XL1 (Extra Large).
Why Choose Regine® Grooved Diamond Tweezers
-
Precision Center-Grooved Alignment Channel: The longitudinal groove machined into the tip centers round girdles and cylindrical pins instantly, preventing gemstones from twisting sideways or snapping free.
-
Diamond-Coated Serrated Jaws: Surrounding the center groove, micro-serrated teeth grip polished facets securely with distributed contact pressure to prevent girdle abrasion.
-
Anti-Glare Satin Finish: Matte brushed surface diffuses harsh inspection lights, allowing clear evaluation of color saturation, clarity inclusions, and laser inscriptions.
-
Spring-Tempered Stainless Steel: Swiss-grade stainless alloy provides balanced spring return, resisting deformation, bench chemicals, and hand perspiration over years of daily handling.
-
Four Dedicated Tip Dimensions: Covers everything from calibrated melee and small accent gems up to heavy rough minerals and large-carat solitaire stones.
-
Milled Longitudinal Grip Ribs: Machined serrations along the body give positive thumb and index finger purchase during high-volume parcel sorting.
