Any dataset here, as the library's Tabulated material (hgs/bond-1967-o).

# ... load hgs as above, then:
sim = ls.Simulation(
    particles=[ls.Particle(shape=ls.Sphere(radius_nm=50), material=hgs)],
    medium_index=1.0,
    wavelengths=ls.WavelengthRange(start_nm=620, stop_nm=1000, num=81),
)
res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).

About HgS (Mercury sulfide)

Mercury sulfide (HgS) is a compound that exists in both red (cinnabar) and black (metacinnabar) forms. The red cinnabar form has been historically significant as a pigment in art and decoration. In the realm of optics, HgS is of limited use due to its poor transparency and the toxicity of mercury. However, its semiconducting properties have attracted attention for potential applications in photodetectors and other optoelectronic devices. Caution should be exercised when handling this material due to the inherent risks associated with mercury. Mineral: Cinnabar

Other names: Mercury sulfide, Mercuric sulfide, Mercury sulphide, Mercury(II) sulfide, Cinnabar, Vermilion
