I like to talk about different things that we run into with gems. The other day I was thinking about ‘windowing’ and what causes it. I do not know if there is a more scientific name for this occurance in gems. I’ve seen this with gems in jewelry stores before. At times its been fine jewelry that costs a pretty penny. Other times I’ve noticed this in ‘cheap jewelry. In the past I’ve seen some designers try to work with the ‘windowing affect by making the band have stones or designs underneth so theres something pretty we experience with this ‘window’ affect. But, most of the time its just an unforturnate occurance in jewelry.
My question is does anyone have experience with having a gem which has the window affect? Please share why you love it or hate it. Does anyone have any pieces where ‘windowing is used properly to make the gem or piece look cool, different or artsy? I’d love to see some images.

I know cz is notorious for its windowing which I think can be a dead giveaway its not real..though I know this can occur in gemstones and sometimes diamonds..I dont know what causes it.. I know im not a fan of windowing in diamonds or simulants but think its beautiful in colored gemstones..could it be possible it is due to poor cutting of the stone? Or maybe some stones are just more translucent than others..I dont know the answer but it would be interteresting to find out..maybe someone on here is more educated on the windowing effect..

I have a cheapish tanzanite ring that does this, it looks worse in certain angles. At the time of reviving it I had no idea what windowing was and just thought it was lighter in the middle.

Windowing in gems is a highly undesirable characteristic. It is generally the result of a bad cut to retain weight. If the window was very small and the gem excellent otherwise I *might* be persuaded to overlook it.
But probably not.

I don’t have any gems that have windows…it was one of the main things I was taught to ask about (and stear clear of) when purchasing gems online.
I have seen one in person….it was an 8 carat rubellite with just a massive window…it sucked all the color straight out of the stone…. I totally called out the jeweler who was trying to convince me to buy it and they put it away reaaaallllyyy fast.
I personally couldn’t buy a stone with a window, it would bug the heck out of me. Most jewelry designers will attempt to disguise the window or hide it, I’ve never seen one that actually uses the window to highlight another feature of the ring. A bit odd, but each to their own.

Pinched from the pricescope forum:
So what’s a “window”? Well a window is when a gemstone has been cut (typically) very shallow. What you’ll see is a part in the centre of the gemstone that appears to lighten or even lose all of its colour. In effect it’s a window and you can see through it! Why’s that bad? Well, it means the colour is not being reflected back to your eye so it’s negatively impacting on the performance of the gemstone. Small windows can be disguised by using a setting that has a more enclosed basket under the gemstone (in effect it acts as a mirror that helps to reflect the light back to you). But be aware that not all settings will do this and not all windows will close.
