A question for diamond experts about cut

[tulip928]

I would really appreciate some teaching regarding a diamond''s cut in relation to my diamond. I''ve posted before about resetting my diamond because I desired a different setting. Hubby had bought a diamond through a friend without a certification and designed a setting for it. It took months to get the setting to his liking (I was not allowed in on the process). Now I think I know why it took so long and why I was not really thrilled with the setting (too much prong, and too much gold surrounding the .75 stone). Hubby told me it was such a good diamond and that''s why he didn''t mind that it was a .75 and not bigger. After 8 yrs. I decided to buy a setting of my choice, a Royal X prong in platinum.

When I went to pick up the ring, my first impression was that it was set crooked. My salesman took it back to the setter and what was learned is that it was the diamond that was not right. The table and girdle are not parallel, slightly off and I could see it with the jeweler''s loupe.

Now that I am over the emotional disappointment, I''m ready to look at this as an educational opportunity.

The diamond is a good color, G, looks very white, very sparkly, very reflective - is beautiful - I don''t see any dead spots. I can''t see any inclusions with the naked eye - only with a loupe I see 2 small ones. The setter was able to "tweek" the stone so the crookedness is not apparent.

My questions are: how does the fact that the table and girdle are not parallel affect the quality of the diamond? How can it be off like this and still look good? If there was a certification for this diamond where would the numbers address this? Would it be in the crown angle, or would it be the symmetry?

In this situation where the culet is off center -when you look at the stone (outside) an hold it straight to your eye, the internal patterns are off center - so then you center and align the patterns - then the ring is not straight. The stone would have Fair or Poor Symmetry on a lab report.

I suggest you let hubby know if you have not yet, and make a trade up.

Let him know that it is very possible for such a stone to still sparkel - so he did not buy a dud, but that you see the stone as a symbol - but it is NQR.

Find a retailer who will give you a fair trade up deal - maybe even the same one - but use ideal-scopes and all the other stuff you learn here to ensure you get the right ice.

Thanks, Garry - that''s the information I was looking for.

I don''t think there will be any further diamond purchase, unfortunately. This diamond was purchased from a friend of his who dabbles in jewelry making. My husband''s personality is such that he would never admit that he made a mistake in selecting this diamond. He always thinks he''s getting a better deal by doing things the unconventional route, so really this diamond is more symbolic of that

I really admire the guys on this board who are so dedicated in selecting the right diamond for their special gal - it''s really wonderful to see.
