Odd question... because I am just curious

[lakerkobe]

It appears that many diamonds, from what I can tell, are cut to maximize size. I am curious... let''s say you have a 1 carat diamond that was cut for the sake of size and the cut quality is very poor. How much size would you lose if you took that diamond and cut it down to a smaller size to make the proportions ideal?



Just wondering.

Depends on the particulars.

Pavilion re-polishing might not result in too much loss, and most problems can be fixed with pavilion tweaking. However, the crown is a whole different story.

In the majority of cases, such a diamond will inevitably wind up worth less after a re-cut. That is to say, if you had a 1.00ct AGS(X) and it was cut down to a .85 AGS0 it would not sell commercially for as much as it would have as the 1ct woofer.

Due to lack of consumer education size is what matters in the real world… Of course, here on PS you would have a lot of fans cheering you on.

You have a grammatical error my friend

Size is a measurement thing.
Weight is what you mean

 

[Rock Music]

What if a person inherits, say, a 1 ct D IF stone that was cut too deeply (for optimum weight from the rough).

Now you study PS and know you will lose weight, but just want to improve the appearance of your family heirloom.

In this case I assume it would make sense (ignoring the price to recut and the resulting value of the stone after the recut.)

BTW, approx how much would it cost to recut this stone to ideal specs?
Just a ballpark number.
$500 $1000 $3000?

Is it even possible?
Where would one go?
Fly to Israel, Belgium?
Sonoma County California?

Would a cutter even speak to a private individual?
Do PS vendors have the capability.

Would your corner jeweler have a cutting wheel, and think he is competent to recut diamonds?

Sounds like the cutter would only cut the pavilion.
So the diameter of the stone would remain the same, right?

And to repeat lakerkobe's original question.
How much weight might be lost, considering the depth of the average weight-optimized stone.
10% ?
20% ?
30% ?
More?

 

[lakerkobe]

Yeah. I actually typed weight, erased it and typed size. Figured when I typed 1 ct you'd know what I meant. Thanks for the replies. It was just something gnawing away at my brain.

This makes sense... ''cause there rounds that are way too shallow: spready but not brilliant. Such a thing with a depth around 50% will surely be larger in diameter than AGS0 of same weight but you might not take the tradeoff gladly. A one carat rose cut (shallowest cut) would be allot larger than a round brilliant and has no brilliance to talk about.

Really flat rounds are not too common. Proportions that give great brilliance but are not AGS0 can produce larger rounds (the famous 60/60 and anything slightly shallower or with larger tables). For these, larger tables and shallower crowns help spread. It just so happens that stones that are not branded for light return merit are not optimized anyway, eve if they could easily be. ''Guess this is what Garry''s HCA is good for.

More often rounds are cut too deep not too shallow. 80% depth surely is possible and the respecive diamond would be smaller. If brilliance can still look ok for such odd cut details, I do not really know.

Hi Rock.

It all depends on particulars.

A re-cut is not very common in heirloom scenarios, as the sentimental value of the object often outweighs

the concept of changing the character of the diamond great-grandmum wore when she was married back in the old country and then fled to Cleveland. With that said, people have and do get diamonds re-cut in many situations - even heirlooms (so, maybe great-grandmum was a real witch).

There are re-cutting services in many places - both in the US and abroad. Options range from repair of chips, openings, abrasions, scratches etc. to “modernizing” (full re-cut) of Old Mine and European cut diamonds and making an ‘ideal’ out of an ‘icky.’ How much weight is lost? No one can say without knowing the job and analyzing the stone. In some circumstances you may lose only a few points. In large jobs a significant percentage may need to be polished away. It is a case by case situation.

Pricing, as with everything, is dependent on the complexity of the job as well as the level of skill and service. In a very rough (get it?) ballpark, polishing out a scratch might run in the mid two figures USD, if it really is a simple job. For a full re-cut of a moderate sized stone you might expect to pay several hundred or more. Some places charge per carat of the diamond’s initial weight, others charge a flat fee, others vary depending on the nuances of the initiative. You would need to speak with the specific vendor for options and pricing. And yes, there are PS vendors who offer this service.

An added note: Another pricing consideration to keep in mind is getting the stone certified after re-cut, which adds another couple hundred dollars.

I say there are several things to consider. Best case scenario is the diamond is already quite close to "ideal" proportions and starting weight is at upper end of weight range. Then stone would lose less and resultant recut would remain within wieght range. It is difficult to argue for a recut that would change the stone''s weight category, especially at that crucial 1 carat level. A recut for purely asthetic reasons will allow you to do whatever you wish. Then an otherwise poorly cut example of really good material can be recut to produce something really special.

I don''t believe anyone''s going to be able to give particulars for weight loss except the potential cutter. They will analyze the stone for you and give you the best estimate on the final weight. Several individuals do this in the states but I don''t know if names can be mentioned here. I''m too new to PS and don''t want to offend. Price could be in the low thousands per carat range depending, with some minimum agreed upon.

If you''re shopping and you can afford it, this could be a way to get exactly the combination of color and calrity you want in a stone you know will be recut to your specs. Good luck and happy hunting.

 

[strmrdr]

recut cost:
basic recut around $300ct
super-ideal recut around $800ct
8* around $1500-$2000ct

All 3 are available from Wink.

The first 2 are recuts by Paul''s company Infinity Diamonds.
Prices may have change since the last time I heard and dont include shipping and handling costs. If your serious contact Wink.

here's the link to my wife's recut stone and now i'm thinking about recutting her earrings.size means nothing if it doesn't sparkle.
