Great asscher specs but average cut rating...I''m confused

[mia1967]

Although we have already purchased my "perfect asscher" (I just can''t have the ring until my actual anniversary) I often still browse other asschers using PS. I noticed a specific asscher with roughly the following specs:

1.00 L:W ratio
EXCELLENT symmetry
67% depth
57% table

yet - it says it''s an "average" cut! How can that be - what would be wrong? The diamond was rated average by DCD - it doesn''t have sarin specs/ideal scope images or anything like that so what would they base the term "average" on?

Just curious...thanks!

Mia I raised the same question some time back, because I found different answers about the quality of a stone''s cut from different vendors. I think the key question is how stones are rated when they aren''t even in the possession of a vendor. Maybe some of the experts can explain.

Perhaps it has a crown height that's too low?
Perhaps the pavillion step facets do not create the look of concentric squares when viewed down through the table?
I'm sure there are other reasons why it might be considered not an ideal cut.

When I was searching for my asscher, I found a couple of stones that had specs my appraiser specifically told me to look for, and yet the vendor they were listed with considered them only "fair" or "good".

It might be a good example of how there is no industry definition if "ideal", in an asscher cut.

Maybe Jim is trying to be on the conservative side since rating the cut on an Asscher is an iffy proposition - especially sight-unseen.

I don''t think the search engine at DCD is even supposed to be rocket-science diamond cut grading tool

Sure those numbers sound great ! And... unless this diamond is presented with complete specs, DCD does not know any more about it than they post (at least in terms of rough data availability).

As you already know Mia, there is not enough information provided to determine the cut rating. The crown and pavilion angle measurements along with the girdle and culet size would be needed to make that determination.

no one and i mean no one can tell if an asscher is a good one from a sarin file or from a cert.
The numbers and cert give you 20% of the information you need to know at most.
The rest comes from good pictures and a trusted vendor that knows asschers.
They will allow one to quickly dismiss the worst ones but thats about it.

No it is not possible to tell if an Asscher or any other fancy shape is a good one from the Sarin file or diamond grading report, but the Sarin report is a good "starting place" for "us" to start looking within the inventory of a trusted vendor before deciding what to have shipped to us for physical evaluation.

We''ve seen a LOT of Asscher cuts as produced by different cutting houses and are frequently disappointed by what we see being represented as an Asscher by most of them. As dealers, you learn over time to stay within the production of suppliers who have proven themselves to be consistent in their production.
