If you read my blog, you know that I am infatuated with old
stuff. I like old mine colored gems,
even though the cutting is often poor, I like antique jewelry, and my own
designs often have an antique look. I
love the detail and workmanship of the jewelry work of bygone days.
But I also like bling.
And nothing has more bling than a diamond. No wonder, then, that vintage diamonds appeal
to me the most. They are also the only
diamonds that are truly rare. Vintage diamonds
are a niche market, but lately they have gotten renewed attention, and that has
driven up prices.
There are several different vintage diamond cuts. Let’s look at “Old Mine”, “Old European” and “Old
Fancy Cuts.”
Old Miners: The term “old miner” generally refers to
stones cut before the modern brilliant cut was perfected. Old miners were mostly cut before the 1920s
(starting in the 1800s). The true “Old
Mine” cut is cushion shaped, so it is a precursor of the modern cushion
cut. It has a high crown, small table,
and a deep pavilion. The culet is open,
meaning it is cut flat and not to a point.
This changes the light reflection (and protects it from chipping). An old mine cut also has fewer facets. For that reason, old miners have less
brilliance than brilliant cut stones.
But they have a lot of fire, that is, a display of different
colors. Some say that old miners perform
best in candle light.
Old European Cuts: These
are more roundish and flatter than old miners.
They’re also called “Euros.” This type of cut appeared a bit later, in
the mid to late 19th century.
Euros have more facets than old miners, but they also have an open
culet. They are the precursor of the
modern brilliant cut, with the same number of facets (58 to be exact). I also read that both the Euro and the Old
Miner can appear lighter than they actually are in color because the open culet
lets in more light that reflects around inside the diamond.
Old Fancy Cuts: Like
today, vintage diamonds were also cut as marquis, ovals, pear shapes, and
trillions. The way these can be
distinguished as old miners is by their facets, which are overall larger, but
also shorter and wider than modern cuts.
And the overall proportions are different, i.e. marquis shapes are often
“fatter”. Modern marquis are usually
6x3, 7x3.5 mm etc, so they are twice as wide as they are long. Old mine marquis might be 6x3.5, and they are
not calibrated.

One thing that recommends vintage diamonds to me is that
most don’t come from Africa because they were mined before the South African (and
other African) mines opened. Some
originate in India, many in Brazil.
Overall it is nearly impossible to tell origin with diamonds
though. To date, as far as I know,
there’s no sure fire technology available to tell you where a diamond is from.
