Screw-Back. 1 Carat.\u003c\/h2\u003e\u003cp\u003eFour choices in this earring that each sit at or near the top of their respective categories — and they compound each other.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e18K white gold:\u003c\/strong\u003e 75% gold purity, higher than 14K (58.3%) or 10K (41.7%). In white gold, the higher karat means a richer metal with a naturally brighter tone before rhodium plating, and greater prestige in the setting relative to 14K equivalents. For a solitaire stud where the setting is the full design, the metal grade matters.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eE–F colour (colourless):\u003c\/strong\u003e E and F are at the top of the diamond colour scale, directly below the absolute ceiling of D. No colour detectable by a trained grader under magnification. In 18K white gold, colourless diamonds have no warmth in the metal to compete with — the combination reads as pure white light return.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePrincess cut:\u003c\/strong\u003e a square step-cut stone with angled facets that return light in directional flashes. In a 4-prong solitaire setting, the princess cut’s square geometry is framed by four corner prongs that hold the stone at its points — the prongs protect the corners and frame the square face cleanly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eScrew-back:\u003c\/strong\u003e the most secure earring closure available, requiring rotation to open. For E–F colourless diamonds in 18K white gold at this value, screw-backs are the correct closure choice.
