Comment: This 4.14 is what some old Chinese traders can't stop calling 'diamond-ruby.' Intense neon purplish red, so deep and rich that it turns out violet traces, the hallmark of finest ruby. Little black-out, even in lowest light (see night-image with perhaps 20% in dark blue). Fiery luster and fluorescence in all light settings. No window. No treatments. No inclusions. Images taken in natural daylight only (on two days, with more sunlight showing more violet). Red-orange clouds and negligible inclusions are lens-only. AIGS report with 'no heat'. More reports at your pleasure. See additional handshot from an angle with near 100% brilliancy rolling into the gem from one side (the other side then looks darker on photo but not in person, or rather the other side disappears from view under the glitter). See image without brilliancy for best color judgement (intense purplish red). No weight-wasting belly in the back. Flawless hand-cut in almost square cushion shape. 3Nos quality in 9x8mm clean ruby. 90+% brilliancy, especially rare for ruby, allowing the best of both worlds: fine color and full luster in one gem. Hard not to look at it when in sight, once seen, never forgotten. World-class collector gem and investor quality on an always value-up trajectory. Ringsizes over 6 for special occasions or presentation.
