Why doesn't my stone have bursts of colour?

[sirbenson]

I was admiring my grandmother's 5 stone diamond band this evening during Christmas dinner. I noticed that the stones really gave off bursts of colour as her hand moved around. I notice that my solitaire does not seem to do that. I'm not sure if its because I am seeing my grandmother's ring from a distance and mine from up close or if stone is lacking something specs wise. Here are the specs:

Round brilliant: AGS Ideal cut (000)
1.215 carat, H, SI1 (eyeclean)
Diameter: 6.84
Depth: 61.6%
Crown angle: 34.7
Crown height: 15.2%
Table size: 56.3%
pavillion angle: 40.7
Pavillion depth: 42.9%
girdle: slightly thick

Any advice?

Thanks.

Everything looks pretty good! The diameter of the diamond seems to be a bit small, which I am assuming is due to the slightly thick girdle, but not sure if that would affect fire and brillance? The only other thing I can think of is that there are a lot of small inclusions that would be affecting light return. I am sure the experts will chime in....

Thanks. Maybe its my imagination then. I'm no expert but the stone to me is 100% eyeclean and I can't see any inclusions with my naked eye. I don't *think* the inclusions in the stone are major enough or abundant enough to affect the fire and brilliance but then again I'm a total diamond noob

I did notice that the stone was filthy today (which is embarassing to admit, I know....I want to get an ultrasonic soon) so not sure if that had an impact.

Yes, if the diamond is dirty it will have a big impact on overal shine and sparkle of the diamond. I have a GIA triple ex E color diamond and if it is dirty it doesn't look nearly as sparkly as when just cleaned.

Yeah, cleanliness was what came to mind when I read your post.

It doesn't take much natural oil from our skin to kill a diamond's best appearance.
I like to see what I paid for so I clean mine more than once a day.

Maybe your grandmother's ring is full of old cuts? They were cut to be heavy on the fire.

it occurred to me that your stone may need to be cleaned as well. You could give it a quick cleaning yourself with a toothbrush and a little windex, then rinse and dry well. I'll bet it will make a difference.

Dirty Diamond is the first thing that came to mind.

Soak in HOT HOT water with Dawn for a while. Scrub with an old (soft) tooth brush, soak some more, this time in Windex. Then rinse and scrub while rinsing. Dry.

What kind of lighting?

more than likely the virtual facet size of her ring combined with the distance and the direction the light was hitting it was just right for fire.

While at a close range with different size virtual facets white light was seen from yours.
The dirt didn't help any of course.

Thanks for all the advice. Looks like I'll put in a request for my fiance to clean my ring ASAP
We were sitting in her dining room at the time and I supposed the light fixture had incandescent bulbs in it.
