How to distinguish Navigation Properties from regular ones when using GetProperties?

Is there a way to distinguish between a regular collection property and a navigation property on an Entity-Framework class (Database-First)?

I'm currently checking if the object is ICollection and IsVirtual but I feel this could possibly trigger on a regular property that someone has declared as a virtual collection.

Question: Are there any other ways to distinguish Navigation Properties from others?

Context: I'm using this to compare values of any object, but I want it to ignore navigation properties (to ignore circular-references among other things).

foreach (var item in (IEnumerable)obj)
{
    list2.MoveNext();
    var item2 = list2.Current;
    foreach (PropertyInfo propInfo in item.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
    {
        Object v1 = propInfo.GetValue(item);
        Object v2 = propInfo.GetValue(item2);

        Primitive = (v1 == null && v2 == null) || IsPrimitive(v1.GetType());

        if (Primitive)
        {
            Assert.AreEqual(v1, v2);
        }
        else
        {
            // Ignore Navigation Properties
            if (v1 is ICollection && propInfo.GetGetMethod().IsVirtual) continue;
            CompareObjects(v1, v2);
        }
    }
}
