The 813-carat Constellation Diamond cut with Synova’s DCS 300 Laser Diamond Cutting System

[@Muonium1]

Some beautiful and interesting physics and chemistry going unremarked on here. The laser is clearly a high power, frequency doubled Nd:YAG system - that neon green color is just unmistakable. But it seems they are using a thin laminar jet of water as a waveguide for the beam, just like a fiber optic! That's very clever! Also the diamond looks totally black on the cut surfaces, why? It's become graphitized - the diamond allotrope of carbon is only metastable, graphite is much more stable and is what the molecular structure naturally reverts to in high heat. Finally, lasers are by definition just a single color, green here, so why does the beam appear bright cherry RED in some shots like at 3:05? You're seeing the Stokes shifted Raman scattering effect in water! The beam is behind a safety plastic window that blocks the main 532nm green beam and so you can see the red scattered light coming directly from the symmetric and asymmetric stretching modes of the O-H bonds in the molecules themselves! I've never seen that directly before! Wow!

[@InvictusByz]

@@StuartGray Right, because I think high quality uncut gems are astronomically more beautiful than the same cookie cutter designs I must be some radical hippie who condemns all mankinds labors. I'm not. I just think cut and polished diamonds look generic, boring as hell, and ultimately quite cookie cutter. Not to mention the fact that polished diamond has the visual properties of well polished *glass* unless you are highly trained and using magnification.

[@StuartGray]

@@InvictusByz Everyone else in the world sees the beauty in the cut gem and the way it plays with light. You though think a cloudy rock is more beautiful. How in touch you are with nature.

[@InvictusByz]

@@StuartGray Right, everyone thinks cut diamonds are just the greatest! That's why the diamond market has consistently expanded to match the growing population of cut diamond loving, economically active population! Except... oh golly looks like it hasn't! In fact, the size of the global diamond jewelry market hasn't increased noticeably in around 10 years. If you want to see light do cool things get some cut glass. Maybe a nice optical prism. Maybe a whole set!

[@StuartGray]

@@InvictusByz I don't give a fuck about diamonds. I do realize, just like everyone else that if you are looking at a diamond. A cut one that captures and plays well with the light is superior in looks to a milky, fractured, expensive rock. It is not hard or complicated and does not require a doctorate in gemology to understand. The only way to not know this is if you are one of those people that need to feel superior and only has the depth of character to pull it off by pretending being contrary makes you superior. It works sometimes till you fuck up and do it somewhere that there are no even subjective positions to make it right. You are just a little person who stroked your ego by saying contrarian, dumb shit online.

Am I missing something or does the wavelength/ color of light keep changing? From green to yellow to infrared to near infrared… Is that just different filters in front of the camera?

[@Muonium1]

I've seen your comments around since we seem to subscribe to the same kinds of channels, even the rare ones like RadiumQuetzal, Nick Moore, and Zenodilodon! Anyway, you have 'tuned in' to some very interesting and subtle effects in these laser diamond cutting videos that I just recently noticed here too. First, it's clearly a doubled Nd:YAG system. I've seen the green color hundreds of times and it's just obvious. Second, look at the color of the beam at 3:05, it's bright cherry RED, but the clue here is that everything else in the shot is amber! It's being shot from behind the laser safety filter glass/plastic in the door! The safety filter is totally blocking the 532nm green fundamental line of the doubled Nd:YAG. So where is the red light coming from? ...It's RAMAN SCATTERING!! I've never actually seen this before but I'm certain that's what it is. The O-H symmetric and asymmetric stretching modes of the water molecule cause a Raman shift of 3410 cm-1 or 118nm. 532nm + 118nm = 650nm, or deep red light. In some shots taken from inside the chamber and on the other side of the filter window the beam appears yellow because green 532 + red 650 = yellow. In fact, I suspect there may even be some Raman lasing going on 650nm due to whispering gallery oscillation modes in microdroplets of the water jet as it breaks up some distance from the outlet probably due to laminar-turbulent transition in the flow, see "Raman lasing near 650 nm from pure water microdroplets on a superhydrophobic surface" by Kiraz et. al. 2009. I think some of the shots appear mostly green and not yellow due to exposure levels on the camera being stopped down and reducing the amount of red Raman light available for the image, preferentially showing the much more intense green. Just a guess but the green shots appear much darker overall than the yellow ones.

[@kodakandladevapriyam6788]

Every good video🎥 views thanks🌹🙏❤ it's clear

[@latinogott]

It's just amazing what lasers can do considering that diamonds slow down natural light speed hence the beautiful colors of the spectrum and scintillation that they produce once finally cut and polished. Thats going to be one beautiful diamond when it's finally presented to the world. Can't wait to see the final footage. Natures gift human technology equal greatness. Great awesome video.

[@stonkintv]

This is the CUT after next process is POLISH where diamond grit (in a disc) rubs against the “charred” carbon face eg diamond & polishes off the black skin... like polish your car! The skill is remove defects & make great intricate shapes that capture & direct the output light. To me more skill in the 3D scanner tech to be sure which points will be removed.... then extra layer of skill if the output cut diamond is to be left / right mirror symmetrical or not where maybe one zone designed to capture more light in so more “sparkles” outward. The huge amount of hours to design & then so many faces to work ultimately together...they are VERY proud NO HEAT as that had been a major source of cracking... imaging working each who day for 7 weeks & then “smash”? Would feel like build a custom car & first day out a hail storm damages every panel & then slide into ditch.

[@stonkintv]

@Draziw Drow Thanks, I agree & had put heat damage risk to back of my mind... because I saw the heavy volume of high pressure water. It is EXACTLY SAME as cooling system I used on a world class Weinig Grinder - German technology for tooling used in wood working industry. I ground High Speed steel, High Carbon High Speed & TCT tungsten (with Diavak wheel diamond grit in resin aluminium wheel body)... when Tungsten TCT 3mm is heavy ground & does NOT get hot - digital probe: never even hit 40 degrees C... just works “cool”. Whether it is wise to laser cut - others can decide. i just understood cleavage diamonds “hit” with hammer can follow an internal GRAIN... just like grown timber has a grain. It seemed like pressure wants to follow weakness in grain eg summer wood fibre less dense than cold winter growth fibre - same logic as tectonic plates - pressure wants to dissipate along weakness not in the line that you like so wastage is lower (higher recovery - bigger output assists selling). Just like grinding tungsten you do last pass very light touch & effectively slow it removes the “chatter marks” even if microscopic - which seems equivalent to POLISH to remove black microns? thick layer caused by laser edge heat for moment. The background showed (imo awesome) raw diamond scan (full 3D shape & internal defects)...there were many cuts to be made to get output more than 1 blank that expert cutters then work on their traditional horizontal surfacing discs with diamond grit. Those jeweller discs seem hugely slower RPM vs what I used 2D working vertically left right. They remind me of a clay pottery wheel 400 years ago vs a F1 Ferrari now. What is interesting to me is the BLACK FACE created a consistent thickness to polish off... my guess is if speed / rate “cut” was steady then black thickness consistent - because the rate of heat transfer to water is consistent... high volume water means contact point water never stays there hot - next molecule in place... this seems to agree with mist created as RUN which is logically nano stream which rapidly drops part of its energy to next molecule as collide. I will reconfirm with my nano-tech Professor brother. Perhaps like silver at nano-scale behaves differently to what human eye observes “macro”. I guesses the machine maker (inventor) liked do eg 3/4 depth cut & then intersect with second cut from second angle results in less wastage... more into several blanks for individual finishing. Else small triangle offcuts - many worthless. To me the clay putty holding the US$1m stone does not want to be crap clay! Sorry Boss - wtf!!!
