Are Royal Asscher proportions patented?

[kenny]

I assume any cutter can cut for beauty instead of weight.

But are the specs of the RA patented?

 

[decodelighted]

Interesting question.

I wonder this too. I can''t see how they could prevent other folks from doing a particular cut ... they just couldn''t name it the same thing. I was under the impression the Cut-cornered-square-step-cuts WERE almost exactly, if not exactly, RA''s pattern.

Like how could McDonalds assure no one else ended up with their secret sauce recipie or something. There are whole cookbooks devoted to "taste-a-likes" of certain propietary foods.

Can''t wait to see what people say!

royal asschers'' unique 74 facet cut is patented.

 

[MacClure]

i agree with ''belle''.....not only because she''s ''belle''.......but, because she''s correct. IMLO (in my lame opinion) the royal''s will always perform differently from asscher cuts simply because of the additional 16 facets (mirrors). for most of this last week, i''ve had (still have) both types stones with me. will i say that the royal is more beautiful than the asscher cut? no. when both diamonds are spec''d closely, it''s all about a difference in ''shape'' and they way they ''perform''. when i write ''perform'', i mean the way they sparkle, glisten, look wet as you stare into them...etc. hope ''belle'', ''deco'' and i have helped...wanna learn a little more? use the ''search'' here and type in royal asscher and read the ''threads''....

 

[strmrdr]

yea its patented but its unenforceable if someone wanted to fight it.
There are others cutting them.

I am not sure the "Royal" has a utility patent..., in this case the specs are not patented...
And even if it was patented back in the early 1900''s it would be void by now...

I assume its ''not'' patented, the name could be with a copyright.

So with 16 additional facets the Royal is kind of like the Solasfera?
More opportunities for flashes of light, but each flash has to be slightly smaller?

interesting analogy kenny. i would say that is pretty accurate.

Don''t some "Cut Cornered Square Step Cuts" have the same 72 facets the Royals do? And if they happen to cut them with the crown & pavillion specs that Royals do ... what makes them any different other than the Royal inscription?

It''s not like Royal Asscher or Fabricant can "hide" the proportions of their stones from the general public - they sell them - any one can post the specs & sarin etc etc.

In my possibly faulty opinion - you pay for a Royal if you want the guarantee that it is their "ideal" specs ... but it is possible to find one with the same EXACT specs of a Royal, same # of facets, same proportions, just without the INSCRIPTION & LOGO ...if you search far & wide enough.

Am I wrong?

74 facets

and 5 pavliion breaks. it is a patented cut. like strm said and you allude to, there are others that copy the cut and nothing but the inscription sets them apart. it is not legal to copy the true ra cut but enforcing it is difficult, so you may find some .... unauthorized reproductions

you''re right.

so let it be written, so let it be done.

wonderful......

......maybe i should search for the royal look-alike. why spend the extra cash on the royal....

 

[kenny]

Indeed.
It is only a matter of cutting the right number of facets at the right angles.

Besides I''m positive even RA''s cutters cannot cut every single facet to a precision spec of .000000001 degrees anyway.
Even the RAs angles will vary within some spec range.

Oh Tierhog! That''s what I was trying to say over on your thread when I mentioned the "Cut Cornered blah blah blah" the problem with ''em is, as you discovered by looking at the ones I mentioned, is that they don''t always have the IDEAL ROYAL other proportions.

ROYAL''s are indeed very, very rare & you know catchin'' ''em is crazy difficult ... And I know you''re a self described "rarity ho" ... If ROYAL''s speak to you, by all means do it! I LOVE LOVE LOVE that 1.23 royal you have there. I would not search forever for one of these look-a-likes to save a couple bucks & give up the ROYAL name -- especially given your awesome choices/ urgent timeline

/ and LOVE of the ROYALS.

Say the "look-a-likes" were actually "more rare" & "more elusive" ... does that make them "Better" ... or "better for you?"

D''s are "more rare" too but I don''t personally adore them! Tradeoffs, tradeoffs.

Don''t put TOO much power in the stone "representing" your and Tanya''s obviously very, very special love. Any stone you choose won''t make THAT "less rare" or "less precious". Okay?

If i am not mistaken, 8 facets are calculated as girdle facets...
And again, in my "sole" opinion its not "utility" patented...
I dont think any Emerald Cuts are patented, since they originate from the Colored, Precious Gemstone "Beryll" aka green Emerald.

All Utility Patents have Angle Ranges....

asscher patent

strmrdr,

Like I wrote, it is not a utility patent, just a Design patent...

There are no Angle numbers or degrees limitations.

Everyone can cut them, just cant call them Asschers....

I believe the patent was granted in the 1920''s and so is long expired (they last about 20 years and give a monpoly to the inventor).

But the name is trade marked - wether it is registered or not.

Then anyone can cut the original stone.
Do you know the differences bt old and new Storm?

Well, I can only add that "Inside Man" has one WAY cool big Royal Asscher. Of course this is Hollywood, with rap music from Bollywood, but the lineage of this diamond was very traceable.
