Are you sure you want to have one in sterling silver. Silver just so
happens to
be the best conductor of heat on the planet.


Actually, Gold happens to be a slightly better conductor of both electricity
and heat than Silver

No! With all due respect, you do not know what you are talking about. Silver
is the best conductor of both electricity and heat. Copper is a close second.
Gold is not even close. It's a distant third

http://en.wikipedia.org/wiki/Conductivity (see "Some typical electrical
conductivities") "Silver - Highest electrical conductivity of any metal"

http://hypertextbook.com/physics/electricity/resistance/ (see middle of the
page "Resistivity of Selected Materials")

but economic considerations limit it's applicability to
really high-end systems. For technical explanation, start at
http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/thercond.html

Interesting. You don't seem to understand what the text on that page is about.
And you give us a link to a page with many links, where you obviously have not
followed some of the links yourself. Besides, that page itself says nothing of
electrical conductivity or thermal conductivity, but rather talks about the "The
Wiedemann-Franz Law"

But for your convenience, I have followed the links for you:

http://hyperphysics.phy-astr.gsu.edu/hbase/tables/elecon.html#c1
http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/rstiv.html#c1

and then there is also

http://environmentalchemistry.com/yogi/periodic/thermal.html


Conductivity:

Silver (http://environmentalchemistry.com/yogi/periodic/Ag.html)
Electrical: 0.63 106/cm ohm (that's 10 to the 6th power, not 106)
Thermal: 4.29 W/cmK

Copper: http://environmentalchemistry.com/yogi/periodic/Cu.html
Electrical: 0.596 106/cm ohm
Thermal: 4.01 W/cmK

Gold: http://environmentalchemistry.com/yogi/periodic/Au.html
Electrical: 0.452 106/cm ohm
Thermal: 3.17 W/cmK

You can put your foot in your mouth now.

Not only that, but just go ahead and polish a heavy signet ring on a
(what do you call it?) big motor thing (like a Baldor) with a big ol'
buff on it, in silver and in gold and see which one gets you to
dancin' cause it heats up SO dang fast & you dare not fling it across
the room!
