➡️ Technical specifications

Twilight Interval is a spinel that thrives on transitions. In daylight, it displays a cool, purplish blue; under artificial light, the color shifts significantly to a warmer purplish pink. The change is not abrupt, but precisely graded – a controlled color field between two states.

Weighing 2.07 carats, this color-change spinel has enough surface area to make the phenomenon clearly perceptible. The cushion cut supports this effect by guiding the light calmly through the stone without creating agitation. Fine natural inclusions remain visible and emphasize the authenticity of the material.

As an untreated, certified color-change spinel, Twilight Interval is aimed at connoisseurs of rare optical effects. Not a decorative play of color, but a gemstone with measurable change – understated, distinctive, and clearly positioned as a character stone.
