AGS Certified 18K White Gold 1.0 Cttw 4-Prong Set Princess-Cut Solitaire Diamond Screw Back Stud Earrings (E-F Color, SI2-I1 Clarity)

AGS Certified. E-F Colour. Princess Cut. 18K White Gold. Screw-Back. 1 Carat.

Four choices in this earring that each sit at or near the top of their respective categories — and they compound each other.

18K white gold: 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.

E–F colour (colourless): 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.

Princess cut: 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.

Screw-back: 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. AGS (American Gem Society) certification: grade independently verified for cut, colour, clarity, and carat weight. SI2–I1 clarity, natural diamonds, 0.50ct per earring.
