How to value "spready" versus customary dimension diamond

[steponapoptop]

I was viewing some of Alex Park's inventory and noticed the term "spready." For the uninitiated how do I value and review a stone like that ? I saw a beautiful pear setting in a prior instagram post and was very curious about perhaps doing something like that instead of a single stone ring. I am sure there is a lot more value in the setting since it has other diamonds and the design is so detailed; however, the price is much higher than the single stone options. Brand new to this but I am excited and very thankful to have a resource like this forum!

Hi Step!
The term "spready" isn't really a technical term, easy to define.
Generally speaking, if a diamond looks large for it's weight, the term "spready" is applied.
Compare it to the word "Buff"
Could be like Arnold ( I'll be back!)....or not

Spread is a real thing.
HCA has an additional Looks Like diamond size relative to its carat weight. There are very large variations and this formula is the main function in looks like - along with an estimation of the light return near the edge of the diamond. (rounds only until someone wants to help me do fancy shapes).

Spread (ct) =(D/6.44)3-C​

I would value it just the same as any similar weight diamond.
Right or wrong thats the market.
I would also give it a more critical look than more normal combos.
Shallow spready stones can suffer from to much response to obstruction and or to a lot of leakage.

An over spready diamond is going to look like a lifeless dull boring lump of glass and will be hard to sell at any price.

I really hesitate to make absolutes.
Of course "spread" is a thing to consider...a big thing...YUGE....
But the term "Spready" is overly general.
I've seen some really shallow stones that had incredible charm-= they could easily be termed "spready"
Rose cuts come to mind

This is about a pear shape.
The proportions that create ugly bow ties are those that make nice rounds.
There are nice shallow pears and nice slightly deep.
So it's horses for courses folks.
