To test the diamond's refractivity, place the stone on its flat side onto a piece of newspaper with lots of lettering . Make sure to use bright lighting and that no objects are casting a shadow on your diamond. If you can read the letters from the newspaper — whether they appear blurry or not — then the diamond is fake.
Are real diamonds reflective?
The way that diamonds reflect light is unique: the inside of a real diamond should sparkle gray and white while the outside should reflect a rainbow of colors onto other surfaces. A fake diamond, on the other hand, will have rainbow colors that you can see inside the diamond as well.
Do real diamonds reflect light?
ilovebutter/Flickr The way that diamonds reflect light is unique: Inside the stone, the diamond will sparkle gray and white (known as “brilliance”) while outside of the gem, it will reflect rainbow colors onto other surfaces (this dispersed light is known as “fire”). ... “They do sparkle, but it's more of a gray color.
Do real diamonds refract light?
Diamonds are so sparkly because of the way they refract and bend light . Glass, quartz, and cubic zirconia may mimic a diamond's brilliance, but they have much lower refractive indexes.
How can the average person tell if a diamond is real?
To tell if your diamond is real, place the stone in front of your mouth and, like a mirror, fog it up with your breath. If the stone stays fogged for a few seconds, then it's probably a fake. A real diamond won't fog up easily since the condensation doesn't stick to the surface.
How can you tell difference between diamond and cubic zirconia?
The best way to tell a cubic zirconia from a diamond is to look at the stones under natural light : a diamond gives off more white light (brilliance) while a cubic zirconia gives off a noticeable rainbow of colored light (excessive light dispersion).
Can I trust a jeweler with my diamond?
I would say that the majority of jewelers in the industry are trustworthy and won't risk jeopardizing their reputation for a small gain. Even for a diamond that is valued at $50,000, it doesn't make good business sense to commit a crime for such a small amount of money.
How much are real diamonds worth?
| Diamond Carat Weight Price (Per Carat, Round Brilliant Cut) Total Price | 1.0 carat $2,500 – $18,000 $2,500 – $18,000 | 1.50 carat $3,300 – $24,000 $4,400 – $32,000 | 2.0 carat $4,200 – $29,000 $8,400 – $58,000 | 3.0 carat $7,200 – $51,000 $21,600 – $153,000 |

What does a diamond look like when it's found?
Diamonds found at the Crater are typically smooth and well rounded. Their shape resembles a polished stone with smooth sides and rounded edges . Size: The average size of a diamond is about the size of a paper match head, approximately 20-25 points weight.
How should a diamond look in sunlight?
Although the sun's UV rays don't affect most diamonds, diamonds with very strong fluorescence glow blue under direct sunlight . While the amount of fire and brilliance is not changed, the diamond's color appears blue. However, even very strong diamond fluorescence will still be faint in most sunlight.
How can you tell if a blue diamond is real?
Most diamonds will reveal blue florescence under a black light; therefore, you'll see a medium to strong color of blue , which means the diamond is real. If you don't see the blue color and instead see a slight green, yellow or gray fluorescence then this usually indicates the gem is not a real diamond.
How much is a 1 carat diamond worth?
According to diamonds.pro, a 1 carat diamond costs anywhere between $1,800 and $12,000 . However, a quality diamond doesn't just come down to size. When assessing stone value four very important factors are always taken into consideration – the four c's of diamond quality: color, cut, clarity and carat.
How accurate is the water test for diamonds?
Since diamonds have high density, if you carefully drop one into a drinking glass with 3⁄4 water, it will sink to the bottom . If it floats in the middle or at the surface of the water, then you know it's not real. Though, this test shouldn't be enough as a moissanite or a cubic zirconia may also sink if too heavy.
How much is a 1 carat cubic zirconia worth?
Cubic Zirconia: Diamonds Price. Cubic zirconia simulants are much, much cheaper than mined diamond. For example, a flawless 1 carat round colorless diamond graded D costs around $12,000 whereas a 1 carat cubic zirconia is only worth $20 .
Will cubic zirconia pass a diamond tester?
Common diamond simulants include cubic zirconia, white zircon, white topaz, white sapphire, moissanite, white spinel, quartz (rock crystal), and glass. ... Note that lab-created diamonds have identical properties to mined diamonds and will pass all of these tests .
What's the closest stone to a diamond?
Moissanite is a form of silicon carbide and is usually produced synthetically. Because of its hardness (9.5 on the Mohs scale), it is perhaps the diamond imitation material that is closest to the real thing in terms of durability.
