Encased Diamonds

[ReLo442]

So It can be done....

http://www.ladiesgadgets.com/world%E2%80%99s-most-expensive-wine-glass/

just happened to come across that. Anyone tried it?

I have some cheap(er) loose diamonds in the safe that I might try it with but Id hate to burn one up.......

[HoneyCombOver]

This is a pretty cool find. I had no idea that borosilicate was compatible with diamond. I wonder if you can drop them in the end of a blowtube like an opal.

TRY IT!!!!!!!

seriously though it would suck to fuck up something that expensive. If you do try it good luck and let us know the outcome.

[JBob]

woudlnt suck that bad...if it went brittle and cracked to shit u can always get a hammer and get that shit back right?

[TlkQ]

CZ man. WAY cheaper and encases without an issue.

You need to get a diamond pretty darn hot to burn it. Its melting point is more then 6,000F But if you do try its a good Ideal to make sure the diamond is clean of any oils and dirt first. (tho then again any discoloration might be a cool effect)

Getting em back from failed attempts might not be to easy tho. Diamonds are very hard but that also makes them brittle to and they can break pretty easy if impacted or preyed on its edges in the wrong direction. So smashing them out might not be to good. But you could prob just nip out the parts around the diamond

[JBob]

couldnt u thermal shock (water) the glass without breaking the diamond or CZ?

[Logan]

If they dont melt till 6000 F, I bet you could put the piece on a raised metal mesh screen and melt out the glass in the kiln.

[T-Rex]

I'll be damned.

from the article:
"made from borosilicate, a glass type known for its high resistance to thermal shock, which maintains the wine’s properties at normal levels while the glass is held in warm hands"

I hate when the heat of my hands thermal shocks my wine glasses. Borosilicate to the rescue!

i think you misunderstood. ;)

graphite melting point is higher than diamond

they must be doing it in an oxygenless atmosphere

or its cz

[3rdI]

I fried one a while back be careful. Melting point is high but burning point was low.

[Collin]

No an easy task. I have fucked up a few diamonds !!!!!!! The Juice is not worth the squeeze.

[kage]

So basically since they're encased, we would have no way if knowing if they are real diamonds or not. Well the price tag is high, so they must be real, right?

[AdamCotter]

I do it, you can also case zircon, but tiny raw diamonds look$.

[Aymie]

Using a real diamond would be foolish. I bet bigmoney these are CZs. When even science cant tell the differemce, why use the real thing? Furthermore, any impurities in the natural stone would result In problems, whereas a cz is pure.

[TlkQ]

Plus CZ is cheaper than fuck. I've considered taking a page out of Abe's book and casing like a hundred cz's and totally covering a piece with them

[Bluemoon24]

CZ's sound like it might be the way to go..

[Aymie]

Very slow heating and cooling to prevent cracking.

[themoch]

CZ will crack on normal annealing cycles in Boro. in soft glass they seem to work way better.

[menty666]

I was always told CZs will burn at boro temps

[purdy]

I've done it with real ones for a company called vanto. Check it out http://www.vantodiamonds.com

[themoch]

nope,

they will crack the glass though, and you can recover them really easily. I've done it like 4 times trying to get it to work.

[purdy]

I promise you it works, i made those 3 years ago and they are still good.

[themoch]

sorry, i meant CZs will crack the glass, but do not themselves crack so you can recover them from boro if it doesn't work out.

[purdy]

Oh ok, thanks for clarifying. Yeah i figured as much since they are essentially glass with a different coe. Real diamonds have such a ridgid structure that they wont under go serious expansion/contraction.

[ReLo442]

been busy the last few days and havent got to check back. By the sound of a few of your posts it seems like real is the only way to go. I will def try to CZ route first tho. Using real ones is like rollin a *cigar* with a $200 bill

[Role]

they are essentially glass with a different coe.

Not at all.

Cubic Zirconia is crystallized zirconium dioxide

CZ is heavy, it is 1.7 times denser than diamond.

It is much much harder than any glass and has a refractive index close
to diamond (but it has excessive dispersion).

BTW, the picture with the blue hair = HOT.

[purdy]

well shit, good to know.

[istandalone24/7]

isn't it all in how you cool/anneal the piece? i bought 20 3mm cz's from fleabay a few weeks ago and have only had the chance to play with them once, but i did the tube encase method just to see if i could, and no cracks. it did look like shit though, there were a few bubbles around the cz.

[Kaizen]

I found to prevent cracking cool the piece in the flame slowly moving it farther back until cool. I flame cooled and took about 25 min but no cracks (small flame and put the piece in a drill so I didn't have to hold it, just moved it back every few min).

And that is a real diamond I scavenged from my mom. She got it back in a nice pendant.

[TlkQ]

Daaaaaaaamn. Look at that shine

[istandalone24/7]

Niiiice!

[LTD]

I've succeeded with real diamonds and cz. It can be done

[gambitglass]

What about herkemer diamonds? They are similar to quartz I believe and are pretty inexpensive? You can mine them yourself if you live in upstate NY.

[purdy]

You can do it with herks fosho

[BORO]

We were talking about diamond encashment just this morning in the shop. I recall a thread with a cz in a wine glass stem? (different thread)

I can tell you from much experience , herks don't usually work. Mabye tiny tiny clear ones? but I live in upstate NY I have tons of herks (for real I bet I have over 2000 pounds of them)

herks/quarts tends to just turn into a bubble cloud.
