What Is Neon Spinel?

Neon-quality spinel is defined by an unusual intensity of colour saturation — the stone appears to glow with a concentrated inner light rather than simply reflecting its surface colour. In Mogok red material, this quality is produced by the stone's natural fluorescence and the optical properties of pure spinel crystal. Neon red material is rare at any size, and Mogok is the only reliable source of the highest-quality examples. For earring pairs, two stones of this colour will produce a striking matched set.
