Orange flor. And chamelion pink

[Brockmccrory]

There is 2 pinks 1 blue and 1 colorless in the bag. Guess what.....I heated the pink up this morning. Hot hot. It turned brown, then colorless, then within a millisecond of stopping heat, right back to pink. Is this normal

you must have nerves of steel

 

[Brockmccrory]

Someone please give me some info on this pink chameleon diamond. Its bothering me that I can not find anything online about it. Is there no one crazy enough to risk destroying a 50k+ $ stone for science and knowledge?

 

[lovedogs]

We can't give you any information from the small and blurry pictures, unfortunately.

 

[Brockmccrory]

New info. I just got it to change to brown using only UV light. Not as drastic or quick of a change, but still a change in color and back.

I’m not sure why or how you are heating them? True Chameleon diamonds change colour for a short time due to either deprivation of a light source for 24 hours plus or upon heating but aren’t necessarily more valuable because of that attribute.
The normal factors for diamond value are more important ie Size, Clarity, cut and colour.
Natural fancy colour diamonds are generally more valuable than their colorless counterparts. However diamonds are also treated to create or enhance colour. Such treated diamonds are of lesser value.
With any coloured diamond you really need a GIA lab report to confirm natural colour.
As for UV fluorescence, many diamonds fluorescence, and in basically any colour except violet. Artifically coloured diamonds can fluorescence strange colours. My yellow diamonds glow vivid neon green under UV. Again, the colour under UV doesn’t necessarily make it worth more or less maybe just more interesting.

Are they graded by GIA or AGS or another lab?

These stones were found in an old abandoned nunnery. Supposedly haunted St. Scholastica Academy in the nunnery they had been using the nuns as free labor to make jewelry. There were cutting wheels and all other diamond cutting tools left there. I found a huge cache of blue and pink diamonds. I took them to a diamond shop and they tested as diamonds. Then I brought them to a local"gia" cert. gemologist and he told me that they are really old stones, but they are not diamonds because they exhibit color zoning. Lol. He need to have his certificate revoked. I had to inform him that fancy colored diamonds exhibit color zoning. So to answer your question, no no certs. The color is unlike anything over seen before.

 

[lovedogs]

Without a cert you have no idea what these stones are.

cz and common commercial grade sapphire. rofl

So I guess that 50 years ago they would have spent the time to cut common saphires down into marquis cut shapes, then nuns would have hidden these marquis and other common diamond shaped cut "saphires" in a cache in between some bricks in their living quarters? I dont buy I. I thought the same until I had them tested with a diamond tester, all tested positive, and I heated them up to over 1000⁰ 3 or 4 times and dropped them into a cup of ice cold water. A couple shattered because several are heavily included, but most, including the pinks, survived the tests over and over. Any opinions on this?

If you don't believe us, then fine. That's your prerogative. But posting about it continuously won't make us think these are diamonds.

St. Scholastica academy in covington la. I had no idea about it being supposedly haunted until I started researching why the nuns were cutting stones there. Still can't find any info as to why. I'm just looking for some help identifying them. The pink turned colors when heated. From pink to brown to clear then back to pink. The same result with heavy uv light. From pink to brownish pink.

 

[Brockmccrory]

I don't know if saphires will survive the heat/ cold test. Will they? And will they turn colors, also what color do they fluoresce

 

[Brockmccrory]

can you give me some info on saphires and let m know if they will act the same as these stones have

A local independent jewelry store with a GIA gemologist would be a much better (albeit less spectacular route) to test your mystery stones. I'm going to hazard a guess these are not a bag of blue diamonds. Trust me, someone would have missed them by now. I mean, if you have a bag of diamonds worth a house, it's time to have a professional test them.

Crack them and heat and cool them to your heart's content, but I don't think you're any closer to figuring out what they are. If they have any value, you may damage them.

PS - Man-made stones often fluorescence under blue light...it doesn't mean much.

No idea what will happen with heating and cooling of sapphires, but they are a hardness of 9. You should look up info on sapphires. If anything, these stones are sapphires or heavily treated diamonds.

 

[Brockmccrory]

I went to a gia gemologist in Covington la. He looked at the stones and said that the stones are very old. (Not sure how he knew that, maybe the cut) however he then said that the stones exhibit color zoning so they cant be diamonds. This is absolutely untrue. Fancy colored diamonds do exhibit color zoning, dont they?

Heating gems and then plunging them into cold water isn’t a way out of identifying them.
Diamonds hardness is a measure of its ability to resist abrasion and is a relative test against other crystalline structures and not whether it survives being struck with a hammer or thermal shock.
The testing that a gemologist does to determine crystal type includes looking for inclusions within the crystal under a microscope and testing the specific gravity and the refractive index. Also a using a dichroscope, Polariscope and spectroscope. It takes the correct equipment, knowledge and training to correctly identify gemstones as many look similar to others.
The types of Gem Testers available are limited and specific. They only measure the heat transfer rate. A jeweller or pawnbroker might use them to quickly ID cubic Zirconia (glass) from Diamond and likewise other types of coloured CZ glass from natural gemstones and Garnet from ruby, amethyst from purple sapphire etc. That said, no gem tester can ID lab grown material from natural as both have the same chemical composition and thus the same rate of heat transfer. A microscope is needed to separate lab grown from natural as lab grown have a distinctive growth pattern (curved striae) and lack natural inclusions.
The gem testing pens from eBay and similar are very unreliable and even the Presidium Gem Tester would not be used by a gemologist. Why? Because there’s now a man made gem with the same heat transfer rate as Diamond! This is Moissanite. However Moissanite has no other diamond characteristics in terms of inclusions AND it is doubly refractive. Here’s my pink Moissanite. It tests as Diamond on a Presidium gem tester.
I think your gems are sapphires. Pink sapphires turn orange under long wave UV lighting. This is due to Chromium.
However subjecting sapphires to heating / thermal shock not only reduces their value because “unheated” is considered more “pure” and better, sometimes there are trapped liquid inclusions inside and heat causes them to expand and possibly shatter the gem. Thermal shock can also turn internal fingerprints into fractures aka cracks. Cracks can render a gem valueless.
So, if you want a proper identification you need a lab report from a trusted source ie GIA or AGL. Lab reports are what buyers expect if you were wanting to sell them. They need proof that the gemstone has been tested for treatments and identified correctly.
Please don’t do any more “at home” testing as you are likely to wreck your gemstones.

Depends on the type of zoning he was talking about, I think. But again, the chances that you just randomly found hugely valuable colored diamonds is approximately zero.

Perhaps destruction-testing what you think are $$$$$$ diamonds might not be the best idea.

Send a sample of the stones to GIA for definitive assessment by a top-tier grading lab.

Until/unless you do that, you can hypothesise until the cows come home but you'll be no nearer the definitive answer you are seeking.

Come back when you have done that and post the reports.
