Rhino: gem file please?

[hbright]

Rhino,

Crown angle: 34.3%
Pav. angle: 40.9
table %: 56%
girdle: medium
carat: 0.845
culet: pointed

crown height: 14.9%
pav height: 43.2%


Stone 2
total depth: 60.9%
Crown angle: 34.1%
Pav. angle: 40.9
table %: 56%
girdle: medium

Hi Hbright,

Without seeing the diamond in hand trying to make a prediction could be very misleading. For example the combination of angles on these next 2 pictures I post are diamonds based on the measurements you gave me on the first diamond (the .84ct) but the differences in the minor facets can change the LightScope image of these stones affecting both their appearance and their light return. I would have different commentary on each one of these stones that would vary in their description and frankly there are hundreds of combinations I could show you.

Even when I've analysed diamonds in certain brands there would be diamonds I would turn down or accept based on this type of analysis and would NEVER endorse a diamond I did not personally inspect. Any appraiser however would say this. So in these next 2 pics are 2 of many possible combinations that you may have.

Sorry I can't be more specific.

Peace,
Rhino

btw, scintillation would be dramatically different between these 2 stones.

Thanks for posting those images Rhino. So facet dimensions affect the stones a lot too? I was hoping for the gem files I could open with the gem advisor.

It'd be great if anyone else could post the actual downloadable gem files for the stones described above.

Thanks.

Rhino can not do what you ask unlesss he sends the stone to someone with a Sarin Diascan or Diamoension.
Ogi machines can not make 3D files.

Fortunately I can accurately measure the minor facets with the OGI that I don't need a Sarin diascan! I can create models that are minor facet specific on any stone I inspect.

Peace,
Rhino

Rhino -

Aren't you on vacation?? And what are you doing up at 3 in the morning?

Have a great holiday!

Thanks Rhino. The diamond I bought has an image more like the first with thinner arrows.

Here's Ideal-Scope image. I adjusted the brightness and contrast to make it look more like what I actually see. It's got some table leakage and some leakage near the hotspots between the arrow tips. It score a 1.1 on the HCA.

Remember, this is a non-H&A branded stone. It's an AGS ideal cut that I handpicked among 3 other AGS ideals which had similar patterns at local B&M (superstore type).

I used a Nikon Coolpix 2500 digital cam with an ideal-scope (thanks Gary!) attachment in the "close-up" mode.

This is a pic of the ring I'd like share. My fiance loves it!

Thanks to all in this forum for educating me!

Rhino I emailed you about this. It is a completely different thing than knowing the length of lower girdle facets that the Sarin 3D scan lets you do with DiamCalc2.
You can work with the actual model of the stone with every facet placed in its actual real world position, so if one facet is slightly tilted, then the what you see is the effect of that tilt.

Good Lord HBright! What a blazing ball-of-fire.

That thing is a traffic hazard.
