Is there any way that just the top can be polished without
recutting the entire top of the stone?
That’s an interesting question and I suppose it depends on the stone
under discussion, ie. how extensive the wear on the table edges -
and of course what shape it is. That’ll make a huge difference.
For a round brilliant, my assumption is that if you only recut the
table facet, the crown facets will no longer meet corner to corner
(table to kite - the kite’s top point will be cut off, star to star
will have a line separating them rather than point to point
meeting), and therefore you’d have to recut all the upper facets.
Even then it may be better to recut the whole stone. If it had a
thick girdle, then I’m guessing you could recut the upper facets
only, just leading to a reduction in height of the upper part of the
stone and therefore the overall height of the stone and the thickness
of the girdle would be reduced.
For a trillion, oval, pear, marquise, the same would apply I would
For an octagon/emerald cut, then it is more likely that you could
get away with just recutting the table as the crown facets are
parallel to it so the facet to facet junctions are not as critical as
the other cuts.
Just my humble opinion based on observation of the different cuts
(I’m a wannabe faceter at heart)
