You can edgewind copper strip. Copper is one of the best examples of malleable that there is.

I reckon you could tell them apart by mass spectrometry or
radioactivity. True old diamonds will be severely C14 depleted.

The artificially created diamonds are actually better.
The propaganda to use "real" diamonds faces a loosing battle.

I remember when De Beers et al. were pushing "expert suggestions" that
the right price for an engagement ring was _four_month's_pay_.

Hint: the right sort of girl to marry is the sort who'd be charmed by
the idea, and then give you a dope slap for making her start out married
life in a financial hole that large.

A wedding could cost 10 months pay. Ours cost $20, and another $25 for
the wedding feast afterwards.

 I told my daughter early on when she decides to get married, to just
elope and I'd give her $20k for the down payment on a house.
She married a guy in the military, they bought a house with a zero down
mortgage. I funded both of their Roths, then he found a girlfriend
she divorced him and he will retire with my funds, but he's probably
stupid enough to spend it. She's married again, they paid for a
very nice wedding on the beach in front of a place they rented that
sleeps 37 people and every one stayed a day or two, best party I have
every been to.
 She has now graduated as a dentist, this how I like to think about.

It was sweet. A really nice lady in a black robe married us in the
beautiful rotunda of SF City Hall. That was the $20. Stars Cafe was
the feast.

(401 on that link.)

I paid for two daughters' pretty-big weddings, one in Austin and one
on a golf course near Lake Tahoe. The bride and groom came down the
isle in a golf cart and almost wiped out a couple of bridesmaids.
Austin, I mostly remember the mosquitoes.

So far, neither looks to need another guy.

Girls are cute but expensive.

My brother's divorce did cost in a similar range. Both he and
she were fully qualified lawyers, albeit working in completely
different fields. First, they moved the material stuff to a
different treaty, zeroing the financial value of the case. Then
my brother represented both himself and and his ex as a lawyer.
Net result was just the writing cost of the court.

Such a thing takes some discipline.

Ours was fairly cheap too--$750 for the hall (Cecil Green Park at UBC),
$500 for the band, $150 for the officiant, and all catered by relatives.

Best wedding I was ever at, just about 39 years ago. According to Isaac
Asimov, he used to introduce people to "Janet, my first wife." (Neither
married more than once.)

She always responded, "Oh, Isaac."

Maybe we the solid state guys should start looking ar graphene. Already
light weight but extremely strong sports equipment are being made with
this material. The base material for gtaphene is abundant(compared to
copper) and processing it much simpler.

Just as a point of interest, in Panama City Fl. we have a port. There
are many semi trucks coming out of the port with 5 stacks of copper plates
evenly dispersed on the trailer. They are 12" to 18" tall.
