    Gemstone Description
    This 1.43 ct natural violetish blue spinel is a gem full of personality and subtle drama. Expertly cut into a sharp octagon, it displays a rare and refined play of color: under daylight it reveals a deep steel blue, while under incandescent light it shifts toward a soft violet-gray tone.

    This optical duality makes it an exceptional choice for designers and collectors alike. Eye clean to the naked eye, the stone contains only minor solid inclusions, visible only under special lighting with microscope and fiber optics.

    Its combination of crisp geometry, color-shift behavior, and natural origin—without any heat treatment—makes it a perfect gemstone for custom jewelry, especially modern engagement rings.

    Elegant and intriguing, this spinel captures attention without shouting—just like the finest things in life.
