A couple of things 1 native cut (done a lot in India) is designed
to give coloured stones a maximum of saturation- so their girdles
are thicker than machine cut stones. more colour looks great in
most stones that are faceted..
So the principles of “flashiness” (which may be a better word than
bling) are general to all translucent/transparent stones?
Do you or others know if there is a gemological rating of “overall
flashiness” (which might incorporate reflectance, refraction and
2 the more light reflected through any stone that is faceted the
more it sparkles. simple but true. even rose cut (the 'first"
faceting method" used in ancient stone cutting centres used that
style a lot, until equipment and math played into the operation
then it got more intricate- in fact some architecture was the
inspiration for gem cutting in India to evolve (read about the Taj
Mahal and Shah Jahan's other palaces and you'll get info about the
evolution of gem cutting in India that was taken along the silk
road to other cultures through the gemstone trade)
Maybe you can talk to the wiki people then re the wiki, /Diamond_cut
because they say in agreement with Paterson’s book that cuts can only
be traced to the Middle Ages and before that only the natural
octahedral crystals were used in jewelry while anhedral stones were
not used in jewelry. But I am sure that there are museums/archives in
India which give a much better history on this than I have seen
anywhere. Any Indian jewelers here? I have never seen a picture of a
diamond crown for example, from Ancient India. If they cut diamond
one has to wonder how they did it.
3 I wouldn't set 100 stones in plastic and then into anything-
just my taste! but illusion settings seek to make a single stone
appear more. large, reflective, etc. same principle. so you may
want to read about illusion settings
Well, I wonder about the blind culture thing. If celebrity A is
wearing one million $ in stones and B is using glass which is of the
same size and colour, how close do they have to be before layman or
expert knows which is which?
4 you can't believe everything you read in books. stone cutting,
faceting in particular, pre-dates Venetian cutting by a few
thousand years in India. India was faceting them 5000 years ago,
Egyptian civilization were cutting stone material before that..
I’d like to see the pictures.
5) polishing evolved with the realisation that different grits of
different materials, including diamond, tin, etc. produced a more
and more shiny surface on crudely cabbed stones- that's where
Venice probably comes in combining what was known about angles in
faceting and polishes. it was a centre of education and
experimentation. and artistic freedom.
Rough anyhedral diamonds are rather drab. I wondered if polishing
might gloss them up? Otherwise, again, is there a rating on how far
one can go with polishing to increase the “flashiness” of stones?
Suppose the stone is a faceted garnet. I have one here as it is my
If we are scientific about this, the facets (which look like diamond
facets) will increase the score on a flashiness scale and the cutting
will do likewise and overall you could sum the score.
then came the period of the Inquest. if one notices the jewels on
imperial "wear" before the 15th c. you'll see many rough cut gems,
that were varied, and lots of pearls worn by Rulers, Monarchs,
Popes/Religious, Habsburgs, etc.,..things changed after the
Inquest. you begin to see more faceted polished materials worn by
the upper classes as well as those that already had "bling"
I don’t see anything wrong with celebrities (or monarchs) wanting to
look “flashy” of course. It just made me ask a lot of questions when
I read the book.
..There is evidence that Vikings polished stones that were thought
to have come from Ceylon, and Asia. go figure that one out. Read
I was gardening today in a slight drizel. There were a lot of small,
naturally tumbled (opaque) stones in the river sand mixed with the
soil. Some were very pretty with a little water and some sunlight. Do
you think synthetic polishing would do any more to make them flashy
than the tumbling plus water?
