🧙Gandalf's ring had a red stone, but what was the color of the band?

[Helm]

The stone on Gandalf's ring was red, but what was the colour of the band of the ring?

The stone on Gandalf's ring was red, but what was the colour of the band of the ring?

While I'm not aware of any literary references, it was created at the same time as the One Ring, using the same techniques of forging (Sauron stole the techniques from the elves, correct?). If the One Ring is commonly assumed to be gold, I would imagine that Gandalf's ring would be the same. I'm under the assumption that smithying varies enough between metals (silver, gold, whatever) that Sauron's theft of forging techniques would be limited to the same metals that the elves were currently using. I worded that awfully, but I hope it's decipherable. I would deduct from my limited knowledge that Gandalf's ring is gold.

The Silmarillion tells the types of stones adorning the Three but does not tell the type of metal:

Now these were the Three that had last been made, and they possessed the greatest powers. Narya, Nenya, and vilya, they were named, the Rings of Fire, and of Water, and of Air, set with ruby and adamant and sapphire...

However, Vilya, that Elrond bore—

...and upon his finger was a ring of gold with a great blue stone...

--and Nenya, which Galadriel bore—

On her finger was Nenya, the right wrought of mithril, that bore a single white stone flickering like a frosty star.

--are both described in The Return of the King. Of Narya it only describes the color of the stone:

...Frodo saw that Gandalf now wore openly on his hand the Third Ring, Narya the Great, and the stone upon it was red as fire.

I don’t own all twelve volumes of The History of Middle-earth, I lack the last four, and haven’t read all of the first 8 volumes so it may be discussed somewhere in HOME but if it is I couldn’t say where.

Hammersmith's guess that Narya's band is gold is a good one, but unless someone comes up with something from HOME we don't know for certain.

Thanks, but your remembering that Galadriel's was wrought of Mithril does a lot to shoot down my logic
