{"product_id":"gem-stone-holder-tsk","title":"Gem Stone Holder TSK","description":"\u003cp\u003ePick up, inspect, hold, and position loose diamonds, faceted gemstones, pearls, and micro-screws with secure claw tension. The TSK Precision Gemstone \u0026amp; 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.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose the TSK Gemstone Prong Holder\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eComplete 360° Viewing Access:\u003c\/b\u003e 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.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eDual Claw Configurations (3-Prong \u0026amp;
