Complete 4C Diamond Grading Kit for Jewelry Stores

This all‑in‑one diamond master tool kit is a comprehensive professional solution designed for jewelers, custom jewelry designers, gemology educators and trade‑show exhibitors.  Housed in a well‑built hard‑shell storage case, this kit integrates standard 4C diamond reference panels together with a full suite of gem testing and measuring tools.  One single box covers diamond grading demonstration, gem identification, ring‑size measuring and client consultation, removing the hassle of assembling scattered individual tools.
The left section features industry‑standard 4C comparison panels: carat size samples, complete D‑M diamond color grade, cut illustrations and full clarity scale samples.  Customers can visually observe and compare diamond parameters face‑to‑face.  The right compartment holds a complete practical tool set: diamond selector tester, triplet magnifying loupe, metal ring sizer set, ring mandrel, gem tweezers and multiple auxiliary accessories.  Every tool sits inside precision‑cut lining slots to prevent shifting and damage.
