[6] Platinum group minerals occur many places throughout the world in layered mafic and ultramafic intrusions formed at high magmatic temperatures, such as the Great Merensky Reef deposits of the Bushveld Igneous Complex in Transvaal Province, South Africa and the Precambrian Stillwater Complex in Montana.

[6] Braggite has also been found as euhedral grains in platinum-iron nuggets from alluvial deposits in remote regions of eastern Madagascar.

[7] The possible sources for these nuggets can be traced to ultramafic facies composed primarily of pyroxenites, peridotite and serpentine, and tremolite and soapstone.

Due to distortions in the structure the X site can vary in size and is filled by Pd, Pt, or Ni each having a 2+ charge.

When viewed through a petrographic microscope, under plane polarized light, braggite is white and slightly bireflectant and lacks reflectance pleochroism.

Observing between crossed polars, its anisotropy is distinct in air and is characterized by a purplish-grey to brown-grey tint.
