Diamond And Jewelry Information

John asks…

how can you tell a real diamond, without paying to have it appraised?

Diamond And Jewelry Information

answers:

There are several tests:

1) Diamonds refract light so well that if you hold the flat surface of the diamond against typed print, you shouldn’t be able to see any of the print on the other side of the diamond. Glass or other fakes don’t refract light so well and you’ll be able to see some of the print.

2) Diamonds conduct heat so well that if you breath on the surface of the diamond you won’t see any condensation. Almost all other fake diamond materials will allow the fog of moisture to stay on the surface of the crystal for a few moments.

3) Don’t do the scratch glass test as even though diamonds are one of the hardest materials, you can still crack or chip your diamond this way.

4) Only an appraiser can tell for sure. Even they cannot distinguish between perfect diamonds that were mined and those grown in the lab. Manufactured diamonds are chemically the same as mined diamonds and are nearly impossible to tell the difference. Mined diamonds usually have some form of inclusions (non-diamond material captured inside the crystal) that will identify them as natural, but some perfect diamonds don’t.

Lizzie asks…

how do you tell if a diamond is real or not?

Diamond And Jewelry Information

answers:

I’m sure this will sound too obvious, but why not bring it to a jeweler? If its real, they can tell you almost everything that you have to know to estimate the value (color and clarity) and though it’s very hard to weigh a set diamond, the size will be a general indication of the karat weight.

Please don’t give it a scratch test. Diamonds will scratch most anything, but in doing so, it is very possible to ruin or chip an excellent cut.

Finally, some diamonds (usually in the the >1.5 karat range for quality stones) have a laser etching on the girdle (the ‘rim’ that separates the top from the bottom facets may have a GIA# it has ever been graded), but you will need a very high magnification (100X+) to see it.

Lisa asks…

Can u drill a hole through granite?

Diamond And Jewelry Information

answers:

Well, I guess it all depends on just exactly what type of hole you’re drilling, and for what purpose. Let me explain, most likely you are adding some kind of appliance to your kitchen/bar/bathroom setup? When you are drilling a hole into a granite counter top for this sort of application you need three main tools, first what I use everyday is a variable speed angle grinder, makita is very nice. Second you need a core bit, the is a drill bit hollowed in the center, you want to make sure it is a diamond tip, if it is not a diamond tip you are going to be drilling for quite sometime. Last but certainly not least is water, nice cool water. If you want to ensure a very easy clean core you want to have a cup of water next to you for cooling purposes. So take some scotch tape, a couple strips on the counter covering about three inches out any direction from the actual size of the hole you will be drilling, this will ensure if the granite do crystallize, the face will not chip due the tape holding it together. Mark your hole (measure twice, cut once) I can’t stress that part enough…..different guys will take many different approaches when it comes to starting the actual hole, many experienced installers will rough in the hole with no template at all. I recommend since you probably have never done this before to take a simple piece of cardboard, start your grinder with the core bit attached to it and run the core bit throught the cardboard, (perfect template). Tape your template over your marked out hole, (make sure your template cannot move around). You want to make 100% sure that the cardboard will not move at all, you do not want to scratch the face, (that is a whole different question and answer). Once it is secured, if you do use a variable angle grinder, you want to start it between speeds 3 and 4 and place the running core bit into the predrilled template and allow it to create the soon to be hole, (make sure to try and place the core bit evenly on the top or you run the risk of it jumping off). Once hole is started then turn speed down and start rocking the grinder in a circular motion, and removing and cooling off every time you see the sludge (I say sludge because that is what it looks like, you will understand what I mean) turn to dry dust. Keep doing this for roughly five mins. Depending on how cool you can keep the bit.

Well to go back to your question again, it all just depends on the type of hole.

P.s. If you are doing something like installing a dishwasher, then it is best to use a hammer drill with a
3/8″ masonry bit.

Chris asks…

Which material is the strongest?

I know, some of the objects I listed might sound dumb but I don’t know a lot about either of them.

Pearl, Silver, Gold, Iron, Titanium, Amber, Sapphire or Diamond?

By strong, I mean which one would require the most impact force to bend or chip it?

Diamond And Jewelry Information

answers:

“The Mohs scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.”

Mineral: Mohs scale hardness
Amber: 2.0 – 3.0
Gold: 2.5 (most malleable of metals!)
Silver: 2.5
Iron: 4.0
Pearl: 2.5–4.5
Titanium: 6.0
Sapphire: 9.0
Diamond: 10.0

This isn’t the only physical measurement of “hardness,” of course, but it gives you an idea. Definitely Diamond!

Mandy asks…

Scratched Diamond again!?

Sorry if I wasn’t more specific! My diamond is a 1/2 Carat round pink with some inclusions. I took it to a jewler and it was tested and real and he just gave me an estimate of $1,000 to $1,200 (I only paid $180.00) Anyways I just had it set and then went on vacation! I don’t know when or when but it has a slight scratcth where a visible inclusion is. I know it wasn’t there when I bought it or after it was set cause I ‘ve been examing it like crazy since I got it! Anyways I hope that helps since most of you told me it it fake and that diamonds don’t scratch or chip.
Ok if it is fratured what can I do? I heard you can get them filled or buffed out ??

answers:

Diamond can be chipped by a hard blow.

You might ask, “how can one chip a diamond, isn’t it the hardest substance on Earth?” Indeed, diamond is the hardest substance known to man, but it is not the toughest. Hardness refers to scratchability, nothing can scratch a diamond except another diamond. Toughness, however, refers to crushability – while you could never scratch a diamond with a big piece of steel, you could easily shatter it in a thousand pieces by hitting it with a hammer.
