Pick up, inspect, hold, and position loose diamonds, faceted gemstones, pearls, and micro-screws with secure claw tension. The TSK Precision Gemstone & Diamond Prong Holder is a spring-loaded pickup tool engineered from high-grade stainless steel. Depressing the plunger end extends flexible spring-steel claws that open wide to cage stones securely; releasing the plunger allows the internal spring to retract the claws tight around the girdle. This gives gemologists, stone setters, and watchmakers a full, unobstructed 360-degree view of the stone from all angles without tweezer shadows. Available in both 3-prong and 4-prong configurations across standard (110–120 mm) and compact pocket (65 mm) lengths.
Why Choose the TSK Gemstone Prong Holder
-
Complete 360° Viewing Access: Retractable wire claws suspend faceted gemstones in open air, allowing natural light penetration for loupe inspection, color grading, and inclusion checks without metal jaws blocking the crown or pavilion.
-
Dual Claw Configurations (3-Prong & 4-Prong):
-
3-Prong Models: Optimal for triangular, pear, marquise, and irregularly shaped gems, providing a self-centering 3-point grip.
-
4-Prong Models: The classic standard for round brilliant diamonds, square cushions, emerald cuts, and spherical pearls, delivering balanced 4-corner hold.
-
-
Spring-Loaded Plunger Action: Smooth top push button extends the claws effortlessly; releasing finger pressure locks the tension around the piece for steady, hands-free examination.
-
Slip-Resistant Knurled Grips:
-
Linear Fluted Grip (120 mm): Deep longitudinal reeded grooves provide directional stability and smooth rotation under a microscope.
-
Diamond Knurled Grip (65 mm): Cross-hatched textured pattern ensures firm fingertip traction on compact pocket versions.
-
-
Solid Stainless Steel Body: Durable, non-magnetic, and rust-resistant steel construction withstands daily studio handling, skin oils, and cleaning fluids.
