Its difficult for various reasons, such as the cut quality of each stone, both are of different shapes, faceting arrangements, performance nuances and so forth....Your best bet would be to have a trusted vendor compare two diamonds you were interested in and if you could get a comparison video, that would be really helpful. Some vendors use BrillianceScope which might be helpful if they were able to run the diamonds you were interested through that for you.
Yes but a conditional yes.
Absolutely YES. We can show you comparative sparkle, brightness, fire, patterned scintillation etc. Watch the clips and you''ll plainly see the differences. Hope that helps.

Hi soontomarry,
I will try to help.
Yes but a conditional yes.For the discussion I''m going to assume you mean ''sparkle scintillation'' as observed in spot lighting. Most layman associate scintillation with this appearance although scintillation embodies another type of appearance which is only observed in diffuse lighting and is referred to as ''contrast or patterned scintillation'' (for the differences between the 2 types of scintillation I have an article on it beginning here).
There are cushions with sparkle scintillation that is identical to rounds (as is Square Cushion Hearts & Arrows) and there are cushions with as much scintillation (or perhaps more depending on your preference) depending on the facet structure and proportions of the cushion which reflect light back to the eye as effectively as these Square Cushion Hearts & Arrows but thow back light to the viewer differently.
I would break them down to the following 3 types of sparkle scintillation.
1. Emphasis on broad flash with some pin flash. There is only one brand of cushion that does this by design (August Vintage). If you enjoy a soft appearance, chunky facets and bold broad reflections of light you must see it to appreicate it.
2. Medium sized flash (not bold as above) but mixed with more pin fire flash. This is the type of sparkle scintillation you see in top performing rounds and also in Square Cushion Hearts & Arrows. To many this represents a very nice balance and appeals to many who want a more modern instead of a vintage appearance. These are the most valuable as these diamonds are cut to the same geometry of a modern Hearts & Arrows round. More rough diamond is cut away to acheive to the final product.
3. Emphasis on pin fire flash. This is seen in many modern faceted cushions on the market today though most lack great optics. The reflections are more splintery in appearance and can be brighter or duller depending on the proportions and symmetry.ir
Most cushions on the market fall under category 3 above but cut with bad proportions as there are no official guidelines for cutting cushions. Independant optical analysis is required to objectively judge the light performance with tools you can read about here and on our site as well.
When we are helping clients my first objective is to learn what appearance it is that appeals to their eyes most and there are a number of steps we take to learn this. So a question I would want answered from you is what kind of sparkle exactly appeals *to you*. Do you enjoy bold broad flash, medium sized with pin fire, or emphasis on pin fire?
The best video you could watch to learn your preferences and at the same time get educated on the subject of cushions would be this here (bonus footage here).
More importantly I would want to learn what brightness and contrast patterns appeal most to your eyes (even over sparkle scintillation) as you will most likely be observing brightness and contrast/patterned scintillation more than you would sparkle.
Absolutely YES. We can show you comparative sparkle, brightness, fire, patterned scintillation etc. Watch the clips and you''ll plainly see the differences. Hope that helps.
Kind regards,
