Over the years, we've heard some stories. In fact, I see and hear about many interesting things dealers tell customers due to a lack of diamond knowledge or simply to try and make the sale.

Here's an example: "A jeweler  that we know claims that the brilliance and sparkle in a yellow diamond comes from the color, not the cut, unlike white diamonds."

Say what? Let me set that one straight. Cut is important in all color diamonds, from colorless D to natural fancy vivid colored diamonds.

There is a lot of misinformation out there. So here's where you post your experiences or perhaps you've heard a similar sales pitch and you're wondering if it might be true.

This is the section where we put the diamond myths to rest.

I know that it's common practice to improve a diamond's clarity by drilling holes into them to remove black spots or other impurities, and then filling them with sealant.  My question is:  how does a regular person buying a diamond know if a diamond has been drilled? Sad

The diamond will have a pained look on its face and will be seen leaving a dentist's office. Does that help any?

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.

ooooooh! I wish I had said that! By the way, what did they drill this hole with? Titanium steel?

The angle of the cut has long been established, in each type of cut, to concentrate light!

Diamonds are naturally brilliant, even uncut and cutting enhances this.

1) Diamond has a refractive index of 1.0, which is the same as water.... if you place a real diamond in water, it will disappear. (you WOULD see any drilled holes, though.)

2) Diamonds are unwettable: alluvial/placer mining used to used pitch covered plates that would be tacky under water, the diamonds, and a few other precious stones, will  adhere to these plates while other gravel passes over freely.

If you think you know of gravel that may contain diamonds, try it. A mix of resin and oil/tar, should work. Just get a mix that is barely tacky under cold water. Riffles are not much good because they will catch everything heavy.

I can't think of any diamond-studded gravel nearby...

Yes, that's very helpful.  I'll check for diamonds that look like they're drooling all over themselves, too. Tongue

There is diamond studded gravel in Alberta... I have a PDF, if I can find it, I will upload it.

Well, I looked for it,and it has disappeared like some other stuff- - - I think my program for cleaning then registry, cleans too much... but I will have another look on my other computer and, if that fails, I will get another copy.
