Blue is not just blue – and this 3.51-carat sapphire illustrates that in a particularly compelling way. GLA – Gemmological Laboratory Austria describes its color as greenish blue, while Lotus Gemology classifies the very same stone as Indigo Blue. Two respected institutions, two perspectives on the same color – and that is precisely what makes this sapphire so intriguing. Depending on the light source and viewing angle, it reveals a different side of itself, vivid and layered, as a fine sapphire should be.
At 9.04 x 7.33 x 6.43 mm, it is a stone with real volume and depth. The comparatively large height of 6.43 mm means light travels a long path through the stone – this intensifies the color and gives the blue a richness that shallower stones often fail to achieve. The oval faceted cut is a classic, timeless choice that showcases this depth effect to its fullest. Small inclusions are entirely normal in a natural sapphire of this size and do not affect the overall impression.
What sets this sapphire apart: it shows no signs of thermal treatment – confirmed independently by both Lotus Gemology, one of the world's leading authorities on colored gemstones, and GLA. At a time when the vast majority of sapphires are heat-treated, this is a clear mark of quality.
A sapphire that convinces through its naturalness – and stays in the memory through its color.
