Lock loose diamonds and precious stones securely in place without continuous finger pressure. Manufactured in Switzerland according to horological and gemological standards, the Regine® Stainless Steel Diamond Tweezers with Slide Lock (16 cm) provide hands-free stone security for inspection, grading, and client presentation.
Equipped with an integrated, knurled thumb slide mechanism, this locking tweezer allows you to set the clamping pressure on a gemstone and lock the arms firmly. The interior tips feature a diamond-coated micro-serrated texture that provides multi-point grip on smooth diamond girdles, preventing stones from slipping or shooting across the bench. Its anti-glare satin finish diffuses bench light and microscope lamps to eliminate blinding reflections, while fine lateral serrations along the body ensure controlled handling. Available in four dedicated tip profiles—XFR (Extra Fine), FR (Fine), MR (Medium), and LR (Large)—this series delivers steady precision for stone setters, diamond dealers, and bench jewelers.
Why Choose Regine® Locking Diamond Tweezers
-
Smooth-Action Slide Lock Mechanism: Push the knurled locking slide forward to lock the jaws at your desired tension. This holds stones safely for 360° inspection under magnification or passing to clients without risk of accidental drops.
-
Diamond-Coated Serrated Jaws: Precision cross-hatched micro-teeth on the inside of the tips bite gently into diamond girdles, eliminating stone rotation, pop-outs, and launching.
-
Anti-Glare Satin Finish: Matte brushed stainless steel prevents harsh specular reflections from microscope spotlights and LED desk lamps, ensuring accurate color and clarity grading.
-
Resilient Swiss Stainless Steel: Spring-tempered stainless construction resists bench moisture, skin oils, and cleaning chemicals while maintaining tip alignment and tension.
-
Four Dedicated Tip Profiles: Tailored jaw widths ranging from ultra-fine points for melee diamonds up to broad tips for large-carat gemstones.
-
Ergonomic Ribbed Body Grips: Textured longitudinal ribs along the handle provide a secure resting position for your fingers during fine positioning.
