I'm looking through a gem specialist's eyeglass, searching for the BBC logo that has been recorded inside a little jewel.
The engraving has been made utilizing extraordinary innovation created by Oxford-based Opsydia.
Its machines are the only ones available that can enter the outer layer of a jewel and control its particles.
The logo I'm attempting to find is not exactly a portion of a millimeter wide. Regardless of guidance from Lewis Fish, head of item at Opsydia, I can't see it.
"It is undeniably challenging," he says. "They're purposefully exceptionally fine, and it is truly prepared goldsmiths they are focused on."
Yet, how could anybody need to compose within a jewel?
"The large thing that is occurring in the business is discernibility and straightforwardness," says Andrew Rimmer, the CEO of Opsydia.
He accepts that Opsydia's innovation can enhance the current ways that jewels are distinguished.
There are as of now frameworks for following a jewel, from when it initially rises out of a mine as an unpleasant precious stone, through the cutting and cleaning stage and on to the retailer.
That is significant, as per HRW, on the grounds that "work freedoms infringement, brutality, and different maltreatments have stayed a difficult issue in gold and jewel mining".

It is likewise becoming essential for jewel merchants to have the option to recognize those that have come from mines, known as regular precious stones, and the developing number of precious stones created by machines, known as lab-developed precious stones.
The innovation for creating lab-developed jewels is working on constantly, and they are a quickly developing segment of the market.
Be that as it may, regular precious stones are significantly more costly than lab-developed pearls, so having a dependable approach to differentiating them is significant
Mr Rimmer makes sense of that his frameworks can give that safeguard confirmation, by writing information inside the jewel - information that is difficult to eliminate, yet doesn't degrade the pearl in any capacity.
"Individuals who are making precious stone gems, they need to have the option to show to the customer this is a characteristic jewel and from a moral source," says Mr Rimmer.
Opsydia's precious stone writing machine is the size of an extremely huge scanner. Inside is a beat laser that emanates extremely short laser explodes.
Such powerful blasts can precisely control materials like jewels and different diamonds at tiny scopes.
In any case, simply pointing the laser at a jewel isn't sufficient - the precious stone's construction would dissipate the shaft.
"Precious stone is about the most troublesome material out of the straightforward materials to process with lasers," says Mr Rimmer.
Opsydia's framework tunes the laser so it can go through the outer layer of the precious stone, generally to a profundity of about a fourth of a millimeter.
Rather than haphazardly bobbing around the precious stone, the laser comes to a pinpoint concentration to make the engraving to suit the client's need.
Assuming the jewel needs a recognizable proof number which is undetectable to anybody without strong magnifying instruments, then, at that point, the framework can change the precious stone at the sub-atomic level.
Notwithstanding, in the event that a goldsmith believes that its logo should be noticeable, the laser can be utilized to roll out greater improvements to the carbon construction of the precious stone.
