Si 14k gold square cut diamond earrings

This is a pair of gold earrings I got at that probate sale along with lot's of gold and silver jewelry. I bought it all for very cheap.

These earrings are stamped what looks like " Si " 14k . Anybody know if Si is the maker or what ? The diamonds measure approx. 1/4" across

Thank You

Think that's a princess cut, Billy. You can compare against this chart.

The photos are too pixelated to tell anything.

 

Self-diffusion of Si under anhydrous conditions at 1 atm has been measured in natural zircon. The source of diffusant for experiments was a mixture of ...

I suspect it has something to do with Zircons - but gem-
ites welcome to comment!

 

Thanks Debora

 

My camera doesn’t take good closeups so, I used my iPhone then took photo with camera

 

Use your iPhone magnifier?

 

I did, just don’t know how to minimize photos on iPhone to post from iPhone

 

I suspect it has to do with cubic zirconia.

 

have all your images uploaded to dropbox? that's what I do on android. I know it's a pain working on a phone.

The plastic keeps do seem to indicate a commercial/man-made gem - just my opinion. But maybe a natural zircon is worth more than a ? You'll find out, I'm sure.

 

Good start for a stripper name

 

Find a photo resizer app?

 

More likely it's the manufacture's symbol and nothing to due with the stones.

 

The Si?

 

Seems unlikely to me that anything stamped on setting would ID the stone.

Or what @Hollyblue said.

 

I don't really think the mark has to do with the nature of the stone, but do suspect they are CZ. It has a higher refractive index than diamond, so looks pretty flashy.

 

Zirconia Van der Woodsen

Sorry - I couldn't resist.

 

The pictures are really terrible (sorry, Billy), but the circled spot makes me think inclusion and I would have them checked out.

My understanding from the first message is that they are marked 14K. Which, by no means, rules out CZ (or other synthetics/lab grown).




EDITED TO ADD: Of course, that might just be light reflection.

 

Okay

ok good idea

 

The "plastic" are Comfort clutch ear nuts and have nothing to due with any type of stone expensive or cheap.
