alj I cant believe you posted that....
This is a vvs1 and this is the level of detail as seen under 40x loupe/microscope.

Here is the level of detail in a ~1ct vvs1 wf picture.

Thanks for taking the time Allison.
But 40x is 40x.
Something other than 40x is something other than 40x and as such should not be called 40x.
Something that varies in magnification should not be called one magnification.

Again here are the magnifications of two ACAs on my 17" monitor.
.27 carat 17x
3 carat 8x
Neither are near 40x.

You say this question has come up before and with truth in advertising laws being what they are I'd imagine anything that can be argued as misrepresentation may open up Whiteflash to frivolous litigation.
Still the money spent defending against a frivolous lawsuit is not frivolous.

Personally I don't care.
I'd just hate for your company (which I recommend often and which has brought a beautiful ACA into my life) to have to waste time and money on such a minor geeky thing, but do we live in a silly litigious society.

Again, I personally don't care; I have expressed myself and let it go.
I am posting this only in a sprit of helpfulness.

Your understanding of magnification is incorrect.

Magnification is the process of enlarging something only in appearance, not in physical size.


The angular magnification of a magnifying glass, such as a loupe, depends on how the glass and the object are held, relative to the eye. If the lens is held such that its front focal point is on the object being viewed, the relaxed eye can view the image with angular magnification. The magnification can be calculated as 250mm/f where f is the focal length.

In words, for magnifying glasses and optical microscopes, where the size of the object is a linear dimension and the apparent size is an angle, the magnification is the ratio between the apparent (angular) size as seen in the eyepiece and the angular size of the object when placed at the conventional closest distance of distinct vision of 25 cm from the eye.

It has nothing to do with resizing the image.

Think about it. Have you ever done any lab work with a microscope? I've done a lot of work with plankton. Lets say I snap a picture of a plankton sample on a glass slide with a very high resolution camera. Then I blow it up 100x. Next I take a picture with the same camera through a 100x optical microscope. Are the pictures the same? Absolutely not. Blowing up a picture while not increasing the resolution is not magnification, it's simply blowing up the picture.

Moh, I can''t agree with this as written.

The definition of the word magnify is "“to increase or be able to increase the apparent or actual size of an object”. So, if we’re showing the image that’s approximately 40 times bigger than its actual size in real life, it’s 40x bigger.

That''s not the same thing as saying "this is what you''ll see under a 40x magnification loupe". Under a 40x loupe, you''re isolating an area of the diamond and showing more detail (more information, as Storm mentioned) in that isolated area.

The verbiage on our website under the magnified website conveys the former....the diamond appears 40 times larger on the screen than it will in real life.

Regarding the ''approximately'' portion of your comments....yes, we do live in a litigious society. I''m not fully convinced that any *reasonable* individual would decide to get litigious over whether it diamond is 38 times the real life size instead of 40, nor am I convinced that such a contention would have any specific legal merit, but I suppose it might be easier to just insert the world "approximately" and call it a day.

I believe you are correct. 40x implies nothing about magnification unless stated otherwise. I checked a few diamonds, and they''re a LITTLE off, so maybe they''re more like 39x than 40x, but come on. Here''s a nice quick read about the difference between zoom, what they''re showing, and magnification, what you''re talking about (its about camera lenses, but its the same principal. They aren''t the same thing.

There are two types of zooms - optical and digital. Digital zoom is very much like the zoom in your favourite photo viewing software. You can keep on zooming it, but more the zoom, less the clarity. But optical zoom is different. No matter how much zoom you do, it should have the same clarity. If your camera says 30x or even 100x zoom, beware. The optical zoom would be only 5x and the digital zoom factor will be 6x or 20x. The zoom of your digital camera is usually calculated as optical zoom * digital zoom.

Optical zoom factor of a camera/lens is the ratio between its longest and shortest focal lengths. My kit lens is 28-90 mm , makes a zoom factor of 3x. On the other hand, the newly introduced PowerShot a710 has 5.8-34.8mm, making it 6x zoom. Does that means it can magnify twice than my lens? No! If you are thinking that zoom factor defines the magnification, think again. Because the magnification has nothing to do with the zoom factor. Interestingly, 5x optical zoom in one camera may give thrice the magnification as the 5x optical zoom of some other camera!
