Gemstone cuts and Fabrials


wildcard09

Recommended Posts

Im wondering if anyone knows if Brandon calls out specific gem cut styles when describing gems for Sphere and fabrials. It seems likely specific cuts are better then others rather than it being an arbitrary detail.

Coppermind only says that cut gems hold more stormlight somehow. Hopefully this question doesn't Rafo'd or something.

So what you're telling me is that not only my first edition Words of Radiance, but also my first edition Way of Kings are Dragonsteel guaranteed to be worth at least a sapphire broam in ten years time.

Peter Ahlstrom

I wouldn't go so far as that! Looks like 2-carat cut sapphires are going for about $2000. They printed tens of thousands of copies of Way of Kings. They're not that rare.

MS-07B-3

Ah, so is that the canon size of the gem in a broam?

Peter Ahlstrom

Yes. 2 carats.

Oh, I've been curious about this for a long time. One of my hobbies is working with gemstones, so knowing the sizes (and cuts, because of how light is affected by the cut) of the gemstones in spheres and Soulcasters would be wonderful!

PeterAhlstrom

I'm not sure about the cuts, but broams are 2 carats and the other sizes are proportional to their value.

R'Shara

Thank you, that helps a lot!

would be happy to offer input on cuts, should that ever be wanted

Peter Ahlstrom

The canonization of the cuts is being worked on, just not by me.

This is great to know, thanks! One last clarification though: is this proportionality linear? In other words:

* Since there are 4 marks per broam, does that make marks 0.5 carats each?

* Since there are 5 chips per mark, does that make chips 0.1 carats each?

Or is there some wonky formula with diminishing returns?

Peter Ahlstrom

Yeah, that's it.

Just to clarify, as a jeweler I think those numbers might be a bit on the small side.

A 2 carat sapphire (assuming a standard well proportioned round cut) is going to be about 8 millimeters in diameter.

A 1 ct sapphire is going to be around 5 mm ish.

A 0.1 carat sapphire would be really tiny. Like, about 1 mm in diameter ish? Depends heavily on how shallow the cut is.

It just seems way too tiny (and imagine the poor high-precision lapidarists working on making pennies - diamonds require specialized cutting equipment because they're WAY harder than anything else)

Peter Ahlstrom

Those sizes are pretty much right.

This is the only thing I've found about cuts, and it's pretty much just "yeah it's being worked on."

My personal imagining has always had chips being thin cuts (kind of like the cut of the middle row all the way to the right), marks as either briolettes or navettes, and broams as one of those three leftmost ones on the middle row.
