bee1014 :  A J color diamond that is wellcut should face-up pretty white. When color is visible, it will mostly be from the side or when you are comparing your J to something whiter. So, keep that in mind for the color of any other diamonds you will wear with the J. Our human eyes are pretty good at detecting color, but excellent as seeing contrast or differences. So, while lots of people place a J in white metal, I personally prefer a J in yellow or rose gold prongs. Here is a PS thread to look at more examples. http://www.pricescope.com/forum/rockytalky/j-color-stones-in-platinum-t24731.html

In terms of platinum vs. white gold, they offer different properties. 14k gold is harder than platinum, but more brittle. A prong that fails in gold will generally break. Platinum is squishy compared to gold. A platinum prong will tend to deform not break, so has a better chance of holding a diamond. But, the metal choice is really only one part of the equation. Stick with 6 prongs (or 4 double claw prongs). More metal = more security not just from damanaged prongs, but from bumps and chips.

Ok. I hate to see a bee get misinformed, so I’m going to be the bearer of bad news. On the diamond, Adiamor’s “Affinity” is pure marketing fluff. They do not have a unique cut or cut parameters, they are simply labelling GIA/AGSL “Ideal” as Affinity. Look at the selection tool They seem to be missing a standard grade after Excellent called “Ideal”.  It guarantees nothing about cut quality, beyond a lab-assigned grade, or performance. You still must do your homework. Ask for and read the GIA or AGSL report on every diamond you consider, use the Halloway Cut Advisor (eliminate anything under 1.9).  Ask for ASETs. If you can’t face that, look at diamonds from Brian Gavin Signature Collection, High Perfomance Diamond – Crafted by Infinity, Good Old Gold Platinum Select or Ascendancy H&A. They actually select for performance beyond ideal cut. That is not true of Adiamor.

I looked through their round Affinity Diamonds around 1.0 carat about a very large number fell outside the following parameters, which are ‘ideal’ for rounds.

depth – 60 – 62% – although my personal preference is to allow up to 62.4%
table – 54- 57%
crown angle – 34- 35 degrees
pavilion angle – 40.6- 41 degrees
girdle – avoid extremes, look for thin to slightly thick, thin to medium etc
polish and symmetry – very good and above

note – with crown and pavilion angles at the shallower ends ( CA 34- PA 40.6) and steeper ( CA 35- PA 41) check to make sure these angles complement in that particular diamond – eyeballs, Idealscope, trusted vendor input – check as appropriate

Cavet emptor.

My K colored diamond VS2 clarity I can rarely ever see the yellow this is the only picture where I’ve seen it so under sunlight it definitely looks a little yellow but other than that its always white but i love to see the hints of yellow evey know and then. I always thought i wanted a white clear diamond but this just gives my ring such a unique look to it, i love it!! 😍💍
