[sugarplum]

hi all,

my ering will be plat 950 and i''m considering a wband that is plat 999. does wearing a plat 999 ring with a plat 950 ring harm either one or have any effect on each other? will there be a difference in color between the two?

Hi Sugarplum. Are you sure it''s Pt999?That’s basically pure platinum, which I think would be very dimpled, resistant to polish and extremely scratchable (like lead). Do you have more information?The 5% metal by weight that’s alloyed with platinum to create Pt950 is what makes it hard enough to be usable in jewelry.

well, I know PT 1000 was pretty popular over in Japan. I spent a bit of time looking at them and it sure seemed to be advertised as pure platinum rings. Though I dont read Japanese. And I am pretty sure I have seen some threads on that here...going to have to look around. Though it never made much sense to me. I guess maybe you are only supposed to wear it once a year or something?

My guess is that this is in reference to the Memoire Purity Collection:

yea I think thats what I remember being discussed on here before. I wonder what JQ will have to say about the strength and casting methods of pt999? waiting to see!

 

[diamondseeker2006]

Yes, interesting. They seem to make their rings using a different process than standard casting, so perhaps that makes a difference. My local jeweler told me that Memoire makes the best diamond bands.

you have any pricing info?

Pearlmans carries the memoire line including the purity 99.9% plat. rings. pricing is listed on their site.

I am with John, I think there would be some differential wear over a lifetime. I expect the pure plat wedder would wear out. It is better the band of an Eng ring wears out because it can usually be chopped of 2/3rds of the way and a new part added. This is because 90% of wear occurs on the inside of the hand.

shoot, I would rather buy from De beers tif or cart than a band from Memoire

, even though it wouldnt be 999

 

[sugarplum]

thanks for the input, everyone.

diamondseeker is correct. i''m referring to memoire''s purity collection. i like their single shared prong bands. it''s very pretty in person and you see more diamond than metal. i''m not so sure about the plat 999 though...

 

[JohnQuixote]

99%-100% platinum is also called fine platinum.When cast it has a Vickers hardness of 52 which is simply too low for common jewelry applications.I’m not familiar with the 'hot extrusion' process (thanks for the link DS) but the results have a familiar ring:Some specialty alloys (Pt-Gold and Pt-Tungsten among them) can be heat treated or aged to have twice the hardness but in reality they behave more like steel than precious metal alloys. We can expect new alloys on a regular basis; there are hundreds on the market and twists are being developed all the time.It’s similar to specialty diamond cuts with extra facets – we love to try new things and see where they go. Chacun son goût.

Some will come and go.Those which stand the test of time will stay.

Ritani is another option. They have single shared prongs as well at Pearlman''s.

You can certainly do that, but expect to pay more! Tiffany and Cartier cost more than Memoire just because of the name. I would have bought from Tiffany if the price had been the same, I assure you!

true, although memoire is pricy, they are still less than the big branded company''s.

also regarding the 99.9 plat..here''s what pearlmans said about it when they first started carrying the line:

the new Memoire 99.9 platinum single prong ring from the Purity Collection. 5 years in the creation this ring comes with a written guarantee that if a diamond falls out it will be replaced. Most platinum has a Vickers system of hardness of 120 at 95% pure. This ring has a Vickers rating of 215

I actually strongly considered the single prong setting for my upgrade at one time. I think it is a stunning set and you''d be guarenteed very high quality with the memoire brand...

I was wondering the same thing. My wedding band was made in Germany, 950 pt and 5 tungsten. was told that''s the norm in Germany. My Whiteflash 5 stone is also 950 pt, forgot what the other 5% was. Will the different alloys cause problems if the rings are worn together?

No. 99.99% of people have never even thought of what alloys their rings are made with! My mother even has the forbidden combination of wearing platinum rings with a white gold anniversary ring....no one ever told her that it was a bad thing! And you know what? After 20 years of wear, almost 24/7, there is no damage to any of the rings! Maybe when she is 100 we might have to get a new shank on one of the rings.

We get a little OCD around here...I know, I am guilty, but we are usually overly cautious.

Yeah, you''re right. I''m being paranoid now. Just that so many questions have been asked on this forum, ones I would never have thought of asking like you said, prior to discovering Pricescope- that it started making me question every little detail. No matter how ridiculous it is.

Thanks MrsS. That helps to understand 'hot extrusion.' Some alloys can be aged or heat treated to change the hardness. Nothing wrong with that but they do behave more like tool steel than precious metals when finished: Typical platinum 950/900 alloys finish between 80-135 HV when cast. Pt999 finishes at 215 HV which is in the same range as stainless steel and titanium jewelry (200-250 HV), nickel WG and cold-worked Pt/Ru.

So DS, would you call this group "People 999?" (a little more pure than Ppl950)

Now that''s a good one, John!!!
