I can not remember the thread - but I mentioned and someone asked me to post an image of the diamond I bought for Vera because if had an almost eye visible garnet inclusion.
This is a lousy photo - cant find the pre setting ones :(

If anyone has photos of inclusions they are proud of please pop them on this thread.
I have only seen a few in 44 years!

Awesome :)

There is a similar diamond with a Garnet inclusion in the British Museum (IIRC) in London - I'd love something cool like that!

My 'bluffy' 2.21ct oval has a baby Spessartite (Orange Fanta) garnet inside it. I kinda bought it because of that. I don't know for sure, since you'd have to break the stone open to test the garnet I imagine, but I read up on the type of garnets that grow with diamonds and Spessartite garnets came up in my Google research. SInce the crystal is orange, I figured I'm on to something :D

Question: how do you make good photos of inclusions? Is there a how to? Two diamond I am considering for purchase have small (VVS2) inclusions. I was offered to look through a microscope to examine them in detail. But how do you make these photos? I could hardly see anything under the microscope. How does one train their eye for that?

With VVS2?

You don't train your eye. You use at the least, a loupe. Most non professionals, and many professionals, will need a microscope for that.

Well, I was offered a microscope to view the diamonds I am considering. And I found it hard to see anything at all! Hence my question. I also have a loupe of 10x, 20x, 30x - I can see single facets with it but not really anything helpful to me as a customer. I think you need to learn how to use these things first. And nobody's looking at diamonds this way IRL, do they?

With a loupe, you will. need to practice. I should make a new video on how to use a loupe, it is easy once you learn how. I have better equipment now for doing the video, so I will see if I can make one later today and post it in this thread.

Once you have it down how to use it, start out with your 10X and focus on a facet, most will do this with the table as it is the easiest and largest facet on most diamonds. Then, gradually bring the diamond closer to the loupe to change the focus point until you eventually arrive at the other side of the diamond. Save yourself some headaches, and learn to look through the loupe with both eyes open.

When you have gotten proficient with the 10X, then it is time to go to the 20X and after sufficient time, the 30X. Personally, I never use the higher power loupes. I just go straight to the scope if I know I am going to need a higher power. It is one of the advantages of being in the business, I got to write off the cost of my scope.

With a microscope you can place the diamond in a holder, then focus from the table and down to the culet a little bit at a time. With 10X you already have a fairly wide depth of field. With 60 x you will need to change the focus a little bit at a time.

I always start at 10X and then bring up the power if I want to really zoom in on something.

When I had my office and my laboratory set up at home back in '77, '78 and '79. my wife used to tell on me when we would go out to dinner. "If I can't find Wink, I just go into the Lab. He will be in there with the lights off peering into his scope and oohing and aahing over some inclusion or another."

I sold a lot of color back then, and man, color has some incredible stories to tell under the scope.

Wink,

what a nice, helpful and informative post! Thanks!
I'd be very interested in seeing the video on how to use a loupe. It seems very difficult to me but thanks for trying to explain it. I am not gonna become a diamond specialist any time soon but it really helps me as customer to understand for what am I supposed to look.

Seriously, that's really cool. And no need for inscription :)

Thanks! That is so cool. I guess I was doing all the wrong things :)
For starters, I have closed my left eye, then I have tried to move the ring around and could not focus....Hmm. Gonna try it again tomorrow but thank you for the tutorial.

Yes, colored gems have seriously interesting inclusions, not for nothing emerald inclusions are called and described as jardins.
Precisely right. Jardin is the French word for garden. It's used to describe emerald clarity characteristics because they're frequently heavily included.

Fun fact for those using magnification with emeralds. Surface reaching fissures are often treated with a filling substance to improve clarity and stability. Oil-based treatments tend to show as yellow (left) while resin shows as blue (right).

While we're talking color, how about silk inclusions?

Here's a nest of rutile inclusions in a Burmese Ruby.



"Silk" in corundum is formed by exsolution during cooling. Below are three sets of rutile inclusions (and a few other characteristics) intersecting at 60°, 120° and perpendicular to the c-axis.



Organized bands of silk can be used to create phenomenal optical effects by polishing en cabachon (with a domed top). When planned and executed effectively silk inclusions reflect light perpendicular to the their banded structures, as with this star ruby showing asterism.



You can see more of those inclusions in this IGI GemBlog article by Dr. Nikhil Alfred. Some related info on chatoyancy (also made possible by "silk") and color-change chrysoberyl is here.

Thank you, Wink! What a fantastic educational video! I love the tip to use your pinky to brace the hand holding the item you are viewing. This method should be so much better than whatever it is I have been doing!

Fun fact - the presence of intact silk is proof that corundum has not been heat treated. The silk melts at relatively low temperatures.

Not so fun fact - if you are a jeweler working on a customer's natural sapphire or ruby, be sure it does not get near your torch!

I bought a pin recently and was surprised when I found one of the small diamonds has a sapphire inclusion. I took the picture with my phone, through the 10x loupe.

Wow - I have never ever seen one of those either!!!
You need to get a professional photo blown up for the wall!

If you weren't so far away I'd send it to you for inspection and enjoyment. :D I know in the pictures it looks like there's two inclusions in the stone, but there is actually only one. The other is an internal reflection.

I just bought my self something. Think I am officially now a flawed collector!
Saw this on a vendors site and fell in love. It is 1.5ct G I2 and even the other inclusions are stunning!
The cut is average - but hey, its not always about the cut!
hahahaha

Wow!!! That's some serious baby crystal inclusions :kiss2:
The science nerd in me loves diamonds for this reason. The credit card also loves that I love included diamonds!
could you see the red one in bottom right corner? YouTube compressed the image a lot and made it fuzzy

Thank you for sharing! My science heart jumps! What are the white inclusions? Are they just generally called crystal inclusions? I have a stone with this sort of inclusion and the jeweller just said it‘s a baby crystal within the stone.

They have very high relief which indicates low refractive index - in a different gem I would say gas or liquid inclusions - but that is virtually impossible in diamond.
I have sent the high definition video to Ewen Tyler (found 3 diamond mines including Argyle and Ellendale) and Tom Redicliffe (Merlin). They use assoicated minerals as indicators and know heaps of this stuff.
