when you told him it would be the MOST durable stone, you told him
an untruth. A solid (probably synthetic) sapphire band would be
much more durable.
No it wouldn’t, Corundum is harder than the jades, but scratch
resistance is only a little part of durability. I learned an
expensive lesson when the bottom fell out of a box of synthetic
boules and almost 2 kilos of sapphires fell onto a concrete floor. I
picked up many more pieces than I dropped.
The other attributes for Durable are impact resistance, crush
resistance, abrasion resistance and resistance to chipping and
shattering, better known as toughness. Corundum is rubbish for
toughness. It’s way easier to saw, grind or drill than the jades.
Jade hammers and axes have been around for millenia, a Sapphire one
would probably last an afternoon.
