Question

How can i know the real diamond?? what's the characteristic??

Answer 1

It can cut glass

Answer 2

Identification

Diamonds can be identified by their high thermal conductivity. Their high refractive index is also indicative, but other materials have similar refractivity. Diamonds do cut glass, but other materials above glass on Mohs scale such as quartz do also. Diamonds easily scratch other diamonds, but this damages both diamonds.

Answer 3

one basic step: rub it on sand paper. if it is scratched, it is definitely not diamond

Answer 4

following are some of the characteristics of Diamonds:

1. Brilliance

Brilliance is the internal and external reflection of white light to the eye from a gemstone.

2. Clarity

Clarity is the degree to which tiny marks of nature (called inclusions), are not present in the diamond.

3. Color

Diamonds range from colorless - the rarest and most valuable - to yellowish, brownish, bluish or even reddish.

4. Crown

Crown is the top part of a diamond above the girdle.

5. Cut

Cut refers to the arrangement of a diamond facet. A diamond which is "ideal cut" captures and releases the maximum play of light. Cut can be Ideal cut, Deep cut or shallow cut.

6. Dispersion

Flashes of different rainbow colors resulting from the dispersion of light is referred as Dispersion of a Diamond.

7. Flawless

Flawless Diamonds are those without external or internal blemishes or inclusions seen under 10X magnification.

8. Girdle

Girdle is the circumference of diamond which is usually held by prongs of setting and separates the crown and pavilion.

9. Inclusions

Inclusions are the natural impurities present in a diamond which were formed during the crystallization process. Inclusions can be minute birthmark specks, bubbles or feathers.

10. Pavilion

Pavilion is the bottom part of a diamond below the girdle.

11. Shape

Shape means the geometric form of the stone. Popular shapes include the round brilliant, marquis, emerald cut, pear and oval.

12. Sparkle

Sparkle is the flashing effect produced when a diamond is moved in the light.

13. Scintillation

Scintillation is the twinkling of light that occurs whenever a diamond is moved, even fractionally. A well cut and faceted diamond will capture light from the slightest flicker of a candle. A diamond's unique beauty-the spectacular light show it puts on-is captured in every stone.
