Discolored Omas Paragon Arco?

[AltecGreen]

If the pattern of the standard arco pattern does not suit you, you can look for an Omas Arco Spina di Pesce. It is the same arco material but cut at a different angle creating a totally different effect. This pattern is rare but the pens can be found if you look hard enough.

Wow! I gotta get me one of them thar Arcos!

You're mocking me, aren't you, Fred? I deserve it.

You're mocking me, aren't you, Fred? I deserve it.

Oh, I'm sure he's not. Fred's one of the nicest people around. He probably just liked the pen Ricky linked to, which I've never seen before, and I'm an Omas fan. Ricky always has the most amazing Italian pens.

I personally like the regular Arco better, though, like the one you have. Mine's Arco Verde.

I bought the pen in question from Fred, that's why he's mocking me. I told him I freaked out when I first received it thinking something was wrong. Should've just asked him about it.

[FredRydr]

No mocking. Hey, I have the ballpoint to remind me of that gorgeous celluloid, at least until someone smart buys it! Bert Oser has an interesting display in his shop with a block of that celluloid.

Wow indeed. Similar but dramatically different.

Not much more to be said here that hasn't already been said. I also prefer the standard Arco; and I also like the variation between light and shade. For a fabulous example, you should see it on the 360!!!

That's gorgeous! The Arco Brown looks good on almost any model on which it is used!

dammit...(I don't need more pens right now) lol.

I'm going to return this thread to normal! The term you are looking for, for the shininess if called "chatoyancy." It is a common effect witnessed in various gemstones like tiger's eye, and beryl. I will quote from WikiPedia below as it explains the science of chatoyancy better than I ever could.

The effect can be likened to the sheen off a spool of silk: The luminous streak of reflected light is always perpendicular to the direction of the fibres. For a gemstone to show this effect best it must be cut en cabochon, with the fibers or fibrous structures parallel to the base of the finished gem. The best finished specimens show a single sharply defined band of light that moves across the stone when it is rotated. Chatoyant stones of lesser quality display a banded effect as is typical with cat's-eye varieties of quartz. Faceted stones do not show the effect well.

For a TL;DR, the amount of chatoyancy depends on the way the material is cut. Since it is a circle, the result of the cut changes depending on the side (or the horizontal and vertical tangents for you calculus people).

Thank you! That is very helpful. And now I have a new word in my vocabulary!

Hi Susan - I have the same Omas and the date 2002 is inscribed on the barrel. I have seen two different nib designs, one with Omas with a large O and another with the OMAS letters all the same size. On the bottom of the nib is 18k on one side and 750 on the other. I personally prefer the large O version but I wondered if yours might be the same? Regards

[guy bagnall]

By the way, does anyone know what the 750 means?

[AltecGreen]

By the way, does anyone know what the 750 means?

Percent of gold in the nib. 18 kt is 750 (Technically, it means 0.750)

14 kt is 585.

Hi Susan...

This thread is two years old, and I believe she resold the pen last year or earlier.

'Tis true enough.

I know, right? I should not post questions on FPG.

Always remember. One time there was a round table business meeting and someone suggested a movie about a Shark Tornado. You know the rest of the story.
