Helzberg jewelers ring, is this pink sapphire?

Had this ring for a while and just started looking for information.
inside is marked P 10 k for plumb or solid if i'm correct? it is white gold. also marked HDS for Helzberg. But I would like to know about the stone.sorry for my poor pics.

It might be a coated one; Heltzberg was a mall jeweler.

 

As @evelyb30 said, Helzberg is a mall store.

A big pink stone like this, being that it is set in 10k, I can assure you is a lab created sapphire. And your baguettes are probably white lab sapphire, not diamond.
If this stone was a natural pink sapphire, of this color and clarity, it would certainly be in 18k or platinum.

 

I believe the "P" is a makers mark,for plumb gold the "P" is next to the "K".

 

Thank you all for th information

It's pretty! Give it a good cleaning and it will really sparkle.

 

What is "Plumb Gold" exactly? I have a necklace I wear that has "KP" on the Clasp.

 

Yes, thanks Holly, I am stuck on same question.

I have a poor grasp on the meaning of "plumb" @916Bulldogs123 ?

Thank you so much, Stracci!

 

I like this bit of info:

"the Karat refers to the purity of the gold, while the plumb can be considered to mean 'exact', in the same way that a 'plumb' wall is exactly vertical or a 'plum' surface is exactly horizontal."

 

Do lab and natural pink sapphires fluoresce different colors under black light?

 

The chart at the bottom of this article explains what colors you should see in sapphires. Listed under corundum.
I hope this helps!

Another blurry pic but this is what i get

 

Below is the text from the chart, describing synthetic pink sapphire results:
"Synthetic pink sapphire: Moderate to strong red (lw); pinkish violet (sw)."

It looks like you are getting red to pink color.
Natural sapphire should be orangey in tone. According to this chart.

But seriously, I am relatively sure that this is a lab stone.
A genuine earth mined pink sapphire of this color, clarity and fancy cut would be worth thousands, and wouldn't be mounted in a 10k setting.

 

What she said. There was a fad for coated stones back in the 90s, so that's what I was thinking. Clear topaz and sometimes white sapphire would be coated in another color. (see Mystic Topaz) Lab sapphire is more likely in this case apparently. They wouldn't put a real rock that pink in a 10k setting. And Helzberg wouldn't have sold it. A Tiffany mall outlet might, but it would be in the engagement ring case and might not have a price tag - as in if you have to ask you can't afford it.

 

Thank you! My clasp only has "Diamond" plus below that "KP" just on the clasp. It is a pretty little necklace I got with a group at an Estate sale. The cheap stuff! No numbers at all anywhere on it.
