Is it normal to have shadow's appear in diamonds at certain angles? My diamond is:
1.01 cushion
G color
SI1 clarity
When I look dead on to the ring it appears bright white and perfect, but when I turn my ring on any angle, i see a shadow, it goes away with movement etc...

Is this normal?

[davidelevi]

Yes.

Think of a diamond as a set of small mirrors oriented in different directions - as you move them, some will either get out of the light beam or no longer direct it towards your eyes: they will become dark. The presence of alternate shadow and light patterns is what makes a diamond rather more interesting than a bathroom mirror, after all...

Thanks for your reply, I found the spec's and was curious what you as an expert/professional thought of the quality and what it really means: This is my GIA Certificate:
Cushion Modified Brilliant

Measurements: 6.04 x 5.48 x 3.89 mm
Carat Weight: 1.02 carat Color Grade: G Clarity Grade: SI1
Proportions:

Depth: 71.0% Table: 59% Girdle: Slightly Thick to Very Thick, Faceted Culet: None
Finish:

Polish: Very Good Symmetry: Good Fluorescence: None

Not much that anyone can say without seeing the stone, unfortunately. Cushions are very very variable in their appearance - there's almost square and very rounded corners. Square or rectangular in aspect. Large and small facets. At least three main cutting styles. High Crowns and flat crowns. All of them can look fabulous (or not appeal at all, depending).

If you love it, it's by definition a good purchase!

What you are seeing may very well be contrast brilliance which is a plus.

How do I post pics to this forum?

[davidelevi]

Choose the "More Reply Options" button, then a section entitled "Attach Files" becomes visible. Find your picture file through the "Choose File" button, then click on "Attach this File".

You can either leave things at this point, and any pictures appear at the end of the post. Otherwise, you can click in the post where you want the image to appear, and click on the "Add to Post" link next to each file name in the list.

Alternatively, you can use any image storing site (photobucket, picasa, imageshack, etc.), and post images directly in the post using [ img ] tags.

BTW - we would all love to see a picture of your diamond (and ring), but to have something to say about quality, you should have several good quality pictures in a large scale and in a variety of lighting conditions.

The shadows in the photos seem to be the setting becoming visible through the diamond at a certain angle, which is normal and unavoidable.

Is the last photo of the diamond pretty similar to what the diamond looks like "in real life"? Or is it closer to the third one in the post above? Or neither?

[septbride]

ok good! Thanks!

Normal life, id say the 3rd and 4th pic are about what the ring looks like

[davidelevi]

There's a significant difference between the 3rd and the 4th - this was precisely my question...

[septbride]

See that is what I know, your the expert. I dont really notice a difference. Normally it appears very bright, very white and in sunlight is very sparkly. What are your thoughts...
