Across the room sparkle....?

[gromit]

So, I have come across this term on a number of occasions when describing excellent cut/performing stones...but what size room would this refer to? I mean at some stage I would think that the ''room'' would just be too big, so there must be some parameters. Also, I assume that this may also be related to the size of the diamond.

Any thoughts???

I''ve heard this terminology used, too, but I think it might have more to do with lighting than room size. Hearts on Fire says that you can see their diamonds from "ten tables away" in a restaurant. In an office lit with fluorescent lights, it might be a different story.

Well a well cut stone will throw out more across the room sparkles than a poorly cut one.

A larger diamond will throw off larger flashes than a smaller diamond.

An emerald or asscher will throw off larger (but fewer) flashes because of the large facets.

And yes the lighting is key.
A darker room with tiny light sources is where you'll see this effect most dramatically.

In a car at night and hold your diamond up in front of the rear view mirror and point the table back towards the headlights of the car behind you.
Don't get into an accident when you see the fire.

Thanks sarap333, that''s a good definition. Am testing out my new ring and just wanted something as a fun comparison :-}

Oh, take it to a Home Depot or Lowe''s and you will be blown away by its sparkle! And another fun thing to do is look at its reflection in a mirror in a bathroom under the bright spotlighting many bathrooms have (especially in office buildings, hotels, and restaurants).

Have fun!!!

Yep, don''t even need to be in the car. Get a pretty good effect just walking home at night with cars passing.

I did an experiment a while back, comparing a poorly cut brown diamond I had to my ISEE2. I put them both in the sun, and began backing up to see where the sparkle died out. The flashes (what few there were) from the poorly cut diamond did not go beyond 5 feet. The flashes from the ISEE2 went all the way across the room. At least 20 feet, then I ran out of space.

I think the point is that the better the cut of the diamond, the further away you can see the flash.

I have to comment on this: the sparkles my 2ct rb emits under a tree are amazing. They're so - bold and demanding, they make my old 1ct look positively twinkly.

If that's what an rb can do, I want to see one of storms new asschers in that size!

(on second thought, I don't, cause I'd blow our wedding fund).

ETA: Fly Girl - how saturated was the brown colour? If it was dark - you think that might have had something to do with the lack of sparkle too? I love dark, rich stones but I'm always wondering how far you can go before you start to sacrifice sparkle.

Valerie''s three quarter carat each, round brilliant ideal cut diamond earrings have been noticed from across a decent size restaurant... Definitely forty feet or so. A lot of it depends on lighting...

Cool...I have been doing little experiments by trying to catch reflections of my ring (how insane) but great fun!...and only dangerous when walking down stairs/escalators :-]. And definitely dependant on the type of lighting.

I remember seeing flashes in the earrings of a speaker at our church, and I was seated near the rear.

gromit - to check "across the room sparkle" you can''t be holding your own ring. It is referring to a distance measurement, as to how far away the sparkles can be seen. I know there is another thread here about this, but I''m not having much luck in finding it. As I recall, better cut diamonds have sparkle that can be seen for a greater distance, hence my experiment with the two diamonds I had at hand.

yssie - The brown diamond was sort of a medium brown, and it had fewer sparkles to begin with. What I was interested in was how far away I could see the sparkles that it did emit. And, it wasn''t very far compared to the better cut stone.
