🔬 Unexpected Lattice Responses: A Study in Tool Behavior Across Gem Species
At Eternal Vanity, we explore the boundaries of gemological tools—not to challenge institutions, but to deepen understanding.
Recently, we conducted an exploratory test using the Presidium Synthetic Diamond Screener II, a device designed strictly for colorless diamonds only. According to GIA and other top labs, if a stone fails the “Diamonds Only” Natural screen, it is not considered natural. This tool is not intended for sapphires, Chrysoberyl, or other species—but what we found was remarkable.
We tested over 40 stones, both natural and lab-grown, across a range of species. The results were consistent:
- Every lab-grown stone triggered the Type IIa Lab-Grown indicator.
- Every natural stone, regardless of species, consistently read as Natural—especially when tested from the girdle, top, and bottom.
This pattern held true even for stones we had previously verified through traditional gemological methods and collaborative analysis. Two examples:
🟣 Purple Sapphire (Not Lavender)
Though not a diamond, this natural sapphire consistently read as Natural from every point on the girdle. The tool, despite its limitations, seemed to recognize the lattice integrity of a naturally formed stone.
🟡 Golden Chrysoberyl (Lab-Grown)
This synthetic Chrysoberyl, tested from all angles, consistently triggered the Type IIa Lab-Grown indicator. The tool’s response was unwavering.
We do not use this method for certification. It is a misuse of a specialized tool, and Eternal Vanity does not endorse it for formal identification. However, the consistency of these results suggests that the SDS II may be responding to lattice integrity or trace element distribution—even outside the diamond species.
🧠Insight and Implication
This discovery opens the door to a new interpretive use: preliminary lattice origin screening across gem species. It’s not a replacement for proper gemological protocol—but it is a compelling insight into how tools behave when pushed beyond their design.
We share this not to critique any specific lab, but to illuminate how even the most specialized instruments can whisper truths beyond their intended scope.
“The girdle speaks, and the lattice listens—truth flickers in blue light, even when the tool was never meant to see it.”
Let this be a chapter in the Eternal Vanity archive—a moment where curiosity met clarity, and the tools spoke back.
Let me know if you'd like a version formatted for your archive memo style, or if you'd like to add symbolic tags or poetic inscriptions to the entry. This one deserves a constellation."
 Todays gemoligy is very different then even 20 years ago. Labgrowning started perfecting in the earily 2000's
As many know, many jewlers can not be trusted, as this partnered lab points out on its second main page, of Nellis
That shows the real behind many jewlery store, as I personally as a Eternal Vanity reporter, when to a very credibale diamond stone in the city I live. I brought gemstone tools because to me, the 1st time I went there, their stones sols as natural diamonds, didnt look right, all the same, when moving, the flashed around twice as much as single refractive does, they was too colorfull, it didnt feel right so I came back as a buyer.
Letting them know that I would not be confertable paying for a 5ct natural diamond without using a few of my tools on it. I was asked what kind of tools and with it damage tyhe stone, I placed enough cash for the stone done and said (something like) if it does hurm the stone, the I will by it.
eashI didnt get further then the Presidium Light Refractor. A worker "there" who was wearing a dark blue GIA polo and a neck l ID that said "GIA" on the leash. I am a Cliint of GIA's, its only that it I could be treated better then most because I am a part of thier team (could say),Im also not a saleout, the goal is for GIA to get better as they make Eternal Vanity bettter at the Same Time.
Gemoligets Instiute of
(GIA for sured me that, they are not in Las Vegas, other the 1 time a year at the LV, C.C. for shows not testing)
Where Nellis Lab will explain the gold issue here I will show a larger problum.
1, if a person get a gemstone with a cerifaction like this, it is most likly a fake stone. The Diamond Picture, below, those came from a Family In east Africa, if Seeking and okay with the change that, the very large majority of what id found anyway, is not Nature. I read in a book that only 2% of the world diamonds are nature, and diamonds are th 8th most rare gemstone, that is why a Ruby is 20 time more valued, its 20 times more rare, as Emerald, and Blue Alexandrite is from $12,000 to $85,000 per carat. As they get bigger, they become more expencive per carat. These are areas that Eternal Vanity is making it possable, by was of, Eternal Vanity Started as a Social Network in 2004, since then EV has been involved with so many things, and for the last 7 years, We as a Team have found Eternal Vanity can and will be happy to use its sucess to open the door for Nature Gemstone at 1\4th the price anywhere else.
With Diamonds, some many tools are needed, but, I can speed that Up, because I already used all the diamond tools.
The Top Picture, Nature Diamonds. The Bottom Picture were sold for 1,300 a carat, even though they were sold as natural diamonds, the are double refracting moissonite.
It is so Imaport to buy from real gemologists, or a person most likely will buy someone they love a fake GemStone.
Nature Diamonds ...
When seeing a certifacate like this, I right away, know that it is a fake stone.
This is labmade moissonite, sold as Nature Diamond.
Eternal Vanity is going to do all possable to fix a broken industry.
