It makes no difference and our grand lodge has avoided making a ruling on the matter, however, I wear my ring with the points pointing away,
First, I do not need a ring to remind me of my obligation and
Second, since the compass represents that circle of due bounds, it makes sense to me that the points are the outer circle of that boundary, and I represent the point within it
Last, I know I am mason so everyone I meet should be met as I was first received, on the points.
