A well-formed colorless breyite crystal reminiscent of a stone making a splash in water. Photomicrograph by Aprisara Semapongpan; field of view 1.07 mm.
The author recently examined a 0.71 ct D-color type IaB diamond with an interesting inclusion reminiscent of a stone splashing in water (see above). Raman analysis identified the well-formed colorless transparent crystal as breyite (CaSiO3), a calcium-rich silicate mineral commonly found in sublithospheric or superdeep diamonds. It was hypothesized that this diamond formed in the lower part of the transition zone or the lower mantle beneath the earth’s crust.
Since the majority of diamonds in the jewelry industry come from the lithosphere, each one provides a window into Earth’s intricate geology. Inclusions such as this one serve as a reminder that beauty and flaws may coexist peacefully, whether they add to a diamond’s charm or provide scientific insight.
