About Hingganite-(Nd)
Formula:
Nd2◻Be2Si2O8(OH)2
Colour:
Dark greenish-brown
Lustre:
Vitreous
Hardness:
5½ - 6
Specific Gravity:
4.690 (Calculated)

Member of:
Name:
Named for its relationship to hingganite-(Y), plus the Levinson "-(Nd)" suffix in allusion to the dominance of neodymium in the structure.
The Nd analogue of hingganite-(Y). As zones in Pakistani hingganite-(Y). Second Nd-Be mineral after gadolinite-(Nd).
Hingganites from Bacúch deposit, Slovakia, are locally enriched in Nd, with Nd-dominant areas having 17.8-18.7 wt.% Nd, accounting for ca. 0.56 apfu Nd.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
