If you don't mind potentially damaging the stones (if they are fake), you could see what they scratch and what scratches them. Diamonds are among the hardest substances known and will easily scratch glass, while cubic zirconia (one type of fake diamond) will be scuffed by rubbing it with sandpaper.
But ... is it really important whether they're fake or not? Diamonds aren't actually all that valuable; the price is artificially inflated by a cartel, as you'll quickly discover if/when you try to resell them.
Also, artificial diamonds are "real" (chemically identical to, and just as hard as, naturally occurring diamonds), but typically sell for considerably less even when new (because the supply of these is much harder for the cartel to control). In order to distinguish between an artificial diamond and a natural diamond you'd probably need to look at it with a loupe (jeweler's eyepiece). A natural diamond will have almost certainly have small "inclusions" (pieces of crud) in it, while an artificial diamond probably will not. And remember that in this case, you'll be paying extra for that crud.
By the way, "925" is, if true, circumstantial evidence that the diamond is NOT real ... 925 is the percentage of silver in "sterling silver", and a real diamond is more likely to be set in gold or platinum than in silver.
Of course, it may not even actually be silver; somebody who can make a convincing-looking fake diamond is going to have no trouble whatsoever mastering the ability to stamp "925" or anything else they like on a zinc or nickel alloy.
Take your earrings to a local jeweler who can use a probe to confirm that the diamonds are real -- or not.
Swarovski earrings are not real diamonds, therefore there is no concern about conflict free diamonds. Swarovski jewelry is made from crystals, not diamonds.

Oh, dude, 925 su ch cz on a diamond earring means that the earring is made of sterling silver (925), and the "su ch cz" likely refers to the type of stone used, which is probably cubic zirconia. So, basically, it's a fancy way of saying, "Hey, this earring is not real diamonds, but it's still shiny and nice, so who cares?"
The markings you describe are probably in the metal holding the stones. Take your diamonds to a local jeweler and ask for a determination as to the value of the stones.
To test the authenticity of diamonds in cluster earrings, you can use a few methods: Thermal Conductivity Test: Diamonds disperse heat quickly, so you can breathe on the stone or touch it briefly to warm it up. Then, place the diamond against a glass surface. If it fogs up and clears almost instantly, it's likely a real diamond. Other stones may retain the fog for a longer time. Water Test: Drop the earrings into a glass of water. Diamonds have high density, so they should sink rapidly. If the earrings float or take a long time to sink, they might not be genuine diamonds. Scratch Test: Diamonds are the hardest natural substance, so they should not be easily scratched. You can try scratching the surface of the stones with a material known to be softer than diamonds, like glass. If the stones show scratches, they may not be real diamonds. Professional Assessment: For a more accurate evaluation, consult a professional jeweler or gemologist. They have the expertise and tools, such as a loupe or refractometer, to examine the diamonds closely and determine their authenticity. Remember, while these methods can provide some indication, for a definitive answer, it's always best to seek the expertise of a qualified professional.
I have some earrings that say 14k jad and I was wondering the same thing I thing they are real diamonds and sapphires
There is a special test to use to find that out. Put them in a glass of water and leave it there for 36 hours or more. If you take it out and scratch the "gold" part, it should NOT feel like sandpaper. If it does, it is not a real gold earring.
I'm wondering if my earrings are real titanium?

Kiran diamonds are manufactured diamonds: real, manufactured diamonds.
Now here are a few ways to know the authenticity of the diamond stud earrings. First and foremost, for certification generally, an original diamond comes with a certification from a reputed gemological institute like GIA or IGI, which carries detailed information regarding the characteristics of the diamond. Use a Loupe: The easiest method is to make use of a jeweller's loupe, which is actually a magnifying glass that may help you see any flaws or inclusions in the diamond. There will usually be some kind of natural imperfections in real diamonds; a fake diamond, on the other hand, may seem too flawless. Fog Test: Put the diamond in front of your mouth and fog it with your breath. Since diamonds disperse heat quite fast, if it is genuine, then the fog will immediately be cleared out; if it's some kind of phony diamond, then the fog will stay there for a couple of seconds. Setting Check: Observe the setting at which the diamond is mounted onto the earring. Real diamonds are usually mounted on good metal settings, and fakes on cheaper ones. Water Test: Drop a diamond in a glass full of water. Since diamonds are so dense, they will sink, whereas most fakes will float or hover close to the surface. Have Them Professionally Appraised: This will mean a visit to an accredited jeweler or gemologist who has tools that would legitimately determine whether your diamond studs are real.
