Name:
Named by H. Forir and Armand Jules-Joseph Jorissen (1853-1920) in 1880 in honor of Mr. Pierre Destinez (1847 - 7 April 1911, Liège, Belgium), a laboratory assistant at the University of Liège. Destinez was a member of the Société Géologique de Belgique as early as 1886 and published a number of articles on paleontological subjects as late as 1904.
Sanjuanite-Destinezite Group.
Destinezite was redefined (IMA Code 00-E) as triclinic Fe2(PO4)(SO4)(OH)·6H2O, the crystalline counterpart of the amorphous diadochite.
Structurally related to arangasite.

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.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
