Natural Fracture in Ceylon Sapphire--Spreading??

canuk-gal Ideal Rock Total Posts: 9,195 Last Post: 11/19/2009 Member Since: 4/19/2004	Hello: I have a question or two about the my 3+ carat ceylon sapphire stone, which is set in a ring. When I bought the ring, I was informed about the natural inclusion (hope I am using the correct terminology), but it was set under a claw and, at the time, was barely perceptable to me. I have had the ring almost three years now and wear it on occasion. However upon recent inspection, it seems to me that the inclusion is "larger" and I wondered at the likelihood of it increasing in size. Although I cannot recall injuring my ring, it could be that I simply cannot remember. Is it probable that the fracture is spreading? I am worried about wearing the ring and increasing accidental damage. (sorry don't own a digital camera or I'd send a photo..) Any input would be appreciated here. Cheers Sharon "People who possess great qualities, do not need to show off".

I doubt that wearing the ring can break the sapphire. But it would not be the first gem to have been sold with some temporary fracture filling to make a surface breaking inclusion invisible... Have you ever cleaned at high temperature (with steam or hot water)? On the other hand, it could be that placing a prong over the fracture did chip it further and for some reason it shows only now. These would be the two things I would be looking for, but without ring at hand I hvae no way to tell Ana "The greatest experts are only as good as the sum total of what they have seen."

I do not believe the fracture was treated/filled--as this info. would have to been disclosed to me and although I am over 40 (memory lapses!!) I would have inquired after this fact. Certainly I may be inaccurate as to the origianl size of the fracture--but I do recall the propriator having to point it out to me, as I didn't detect it while trying the ring on. Anyway, if I can get my handy neighbours to take some pics of my ring I'll post them. thanks again slb "People who possess great qualities, do not need to show off".

Lots of sapphires have small fractures and "healed fractures" when you get the rough stones. In order to get the largest gem possible from a piece of rough, you are often forced to leave a small remnant of the fracture in the stone. You always try to orient the fracture vertically, so that reflections off of it don't show up at normal viewing angles. Once you become aware of this imperfection it may appear to be getting bigger, simply because you're focusing on it and viewing it from a more sideways angle, where it looks bigger because you're looking at it from just the wrong vantage point. Sort of like looking at a sheet of paper from the front or at the edge. Sapphire is VERY tough and durable, I seriously doubt that you have any problem.
