I could not find a diamond on p. 112 in my version of the
comprehensive symbol list, but maybe:

\definefontfamily[myface][rm][TeX Gyre Pagella]
\definefallbackfamily[myface][mm][Xits][range={"025C7}]
\definefontfamily[myface][mm][TeX Gyre Pagella Math]

\setupbodyfont[myface]

\starttext
You could try $⋄\quad   ⃟ $ from Pagella or $◇$ from Xits.
\stoptext

There is a nice document, unicode-symbols.pdf you can have a look in
for a list of (unicode) math symbols.
