I am picturing that the holes (being made on an angle from opposing
sides) would form somewhat of a "v" shape inside the bead where the
2 holes meet in the middle. Is this correct? If it is, I would
think that a diamond briolette would not be usable at all as it
will always break whatever it is strung on (even if it is wire).
What do you think?
That's correct, the holes from each side come together at an angle &
form a 'V' shape.
I'm not sure how the holes in diamond briolettes are drilled. But
anything other than a straight through hole will produce a 'wear
point' on the material used to string the bead.
In the second part of your post, you talk about knotting
individually on each side of the stone. I'm not sure what this
The reason for knotting on each side of the bead is to eliminate or
reduce to a minimum any movement of the bead on the stringing
material. The finished article would look something like this. Knot,
diamond bead, knot, knot, diamond bead, knot, knot, diamond bead,
knot & so on to the end of the item. Reducing the lateral motion of
the beads eliminates or reduces the abrasive wear of the point in
the center of the bead. However it doesn't do anything for the shear
forces caused by the point. The only way to reduce those would be to
reduce or eliminate the point.
