For anyone wondering, Khatch Cross or Khatchk'ar translates as Stone Cross and represents an historic type of Armenian monument (they have occasionally been compared to the more familiar Celtic Cross).
It would be nearly impossible to include the detail found in their more traditional styling in one formed of metal and used to surmount a cupola. However, this version nicely suggests the traditional one from which it's derived. One of the Armenian Catholic parishes in either the US or Canada has a nicely done modern one on its website, but I can't remember which parish.
