"agsl # Xxxxx Has Been Escribed On The Girdle Of This Diamond"

Recommended Posts

I'm just now noticing this in several AGS reports.

 

I was a little taken aback when I saw this.

 

Can I see this with the naked eye?

 

Why does someone want this on their diamond?

 

I imagine its for authentication purposes but who wants writing drilled into the side of their diamond?

 

Can someone allay my apprehension on this one?

No worries. Laser inscriptions are commonly done on the girdle; seen only under magnification. The imprint is microns deep (and can be polished off later if desired). It's a good way to quickly identify your diamond if you're dropping off/picking up your ring for service. Most jewelry pros can locate an inscription with a 10X loupe but it takes the average joe some practice, and many people need a microscope to find it.

 

Diamonds accompanied by the GIA Dossier report - which doesn't have an inclusion plot - are all inscribed with the report number by the lab. An inscription must be requested for other diamonds, which it often is: Most people consider it a useful benefit.

 

Note that if you have the inscription done outside the lab after grading it will not be noted in the comments section of the report. This is why many sellers elect to use the labs for inscription services (though they are available elsewhere).

Done for ID purposes, does not affect the structural integrity of the diamond, is usually not visible to the naked eye-only under high magnification ( 20X and higher)and can be easily polished off by a diamond cutter.

 

If you're ordering a ring to go with the diamond, chances are very good that the setting process which involves steam cleaning of the ring will erode and erase the black that is used to fill the etchings of the letters/numbers of the inscription, thus leaving only the white etchings themselves which are very difficult to pick up under magnification.

 

Also keep in mind that over time the inscription will tend to fade from moisture due to wear and cleaning of the ring.

 

Don't sweat this one; it's designed to help consumers.

When the laser inscription is first done, there is a black carbon residue at the bottom of the letters that makes them easier to read against the white background of the stone. Over time this comes out but the letters themselves are still there, they’re just a bit harder to see. Most people have a pretty hard time reading these things with a 10x loupe anyway but with a common gemological microscope it's easy. They’re VERY small.

 

Presence of an inscription has no affect on the visual appearance, durability or value of the stone. It’s done for identification purposes and it is moderately effective at this because a quick glance with a standard microscope is all that’s required to spot it. With the right tools they’re easy enough to erase and replace but it would take some serious criminal intent to do this and the equipment to add an inscription is both unusual and pretty expensive.

 

I think this is going to become more and more common over time. All of the major labs offer this service and with some of their products even require it. It’s a good thing. It's sort of like having a VIN number on your car.

so meaning that even the laser inscription fades after sometimes but it's still visible? ;)

Here is a picture of two laser inscriptions, one with the carbon residue and one without. Hopefully this will help better understand what they look like:

That's a good point gents (and Megan) :unsure: I was answering from an accustomed-to-seeing-them-fresh POV.
