And if I bought one does it tell you how good of quality your diamonds are?

Do you think the ones you buy on ebay are okay?

This is a tricky one. There are many diamond testers on the market, most of these are based on the thermal conductivity of diamond being higher than most of the other materials used to simulate it. A tiny hot point is placed on the stone and the rate at which it cools is measured by the instrument which "bleeps" if the stone is diamond. Regrettably there are now some lab. made stones which also give a "diamond" reading. These instruments are mostly quite cheap. The next type are called Reflectometers and use light reflected from the stone to extrapolate a refractive index figure. These are expensive and also have many drawbacks - for example even a slight finger mark on the stone will produce a false reading as will any small scratches.
With regard to testing the "quality" of your stone there is no such machine, there are vastly expensive colour analyzers which only professional labs can afford but at the end of the day it is down to the eyes of an experienced diamond grader to give you a definite answer.
All in all unless you have experience in handling diamonds the instruments available on the market today are only nothing more than a rough guide to what the stone you are testing really is and will tell you absolutely nothing about how good it is. Do not waste your money on these testers but spend it on taking the stone to a good appraiser and getting the opinion of an expert, it will pay off in the long run.
Sorry if I have sounded rather off putting but in my 40+ years as a professional gemmologist I have seen so many disasters caused by people thinking that you can learn "all about stones" from the pages of a book or two and doing a Google search. You can't - it takes years of specialized training and even more practice.

Have it appraised with the aid of a jeweler. Ask the in-residing house gemologist for their opinion. it rather is real that diamonds do scratch glass yet so do a impressive style of the different fakes on the marketplace. besides, it’s available to injure your rock whether it’s real throughout your hardness attempt. A severe proportion of diamonds fluorescence blue while positioned below an extremely violet gentle (black gentle). via fact that ninety 9% of all fakes don’t, a impressive identity of medium to solid blue might point out a diamond.

Look through the diamond at a piece of newsprint. If you can read the paper than the diamond is cubic zirconium. If not then you have a real diamond.
Really, I would take it to a jeweler. They can not only authenticate the diamond, but they can grade it if it is real (based on weight, clarity, color, etc)
Hope this helps

stay a way , Diamonds tester alone won't help you , You need the expert eyes and life experience

You can find them on ebay. They are on there all the time. Some go for like 100 dollars while some go for 10 dollars.

Only "REAL" diamonds "cut glass" Get a window pane and test it that way.

you dont really need to. take a piece of glass and ur diamond. scratch the diamond with the glass. if it gets scratched, its fake.
