red treasure

The synthesis silicon carbide (Synthetic Moissanite) also names synthesizes the Morsan stone, the synthesis carbon silica (chemical composition SiC), chromatic dispersion 0.104 compared to diamond (0.044) big, the refractive index 2.65-2.69 (diamond 2.42), has with the diamond same adamantine luster, “the fire color” is stronger, compared to formerly any replica closer diamond.

This is Carrow comes that state by the US north C3 Corporation to make the production, had various countries production synthesis silicon carbide patent,honored guests
to the world promotion application. according to the diamond 4C grading standards, the synthesis silicon carbide's color (Color), (Clarity), stone cutting (Cut), and the weight (Carat) characteristic is only:

　Color: At present synthesizes the silicon carbide not to have the achromatic color, many for the shallow celadon, light yellow, the ash is blue. According to GB/T 16554-1996 "Diamond Grading standards" the color level in 96, 95 (H, I) below,diamond ornamentses
(sees next table).

Has the dichroism (diamond not to have dichroism). GB/T 16554-1996 colorless - yellow (brown) diamond color grading standards diamond color rank D 100 extremely white E 99 F 98 superior white G 97 H 96 white I 95 micro yellow (brown, ash) white J 94 K 93 light yellow (brown, ash) white L 92 M 91 light yellow (brown, ash) N 90 < N < 90 yellow (brown, ash) only:

The synthesis silicon carbide is the cubic system, may crystallize to 2-3 inches columnar crystals, the partial material may achieve the IF level (Internally Flawless) in the non-flaw level (in diamond not to contain thing, only then extremely slight slight defect, usually may by polish elimination);

The majority of synthesis silicon carbide has the lemon spot composition thin white striation content, examines many for micro flaw level VS or slight defect level SI. Among them including object space to approximately with tabletop approximately vertical, not completely parallel (has several degrees disparities) mutually; Has the dark color metal globe few.

　Weight: The synthesis silicon carbide proportion is 3.22 (diamond 3.52), is approximately lighter than the diamond 10%. Standard lathe worker who drills according to the garden, when the diameter is 6.5mm, the diamond general weight is 200mg (i.e. one carat).hotel interior design
But manufactures according to the standard lathe worker 6.5mm garden shape synthesis silicon carbide, weight only then 160mg (80 points) many spots.

　In 12 kind of wonder stones which in the fable red treasure is God makes when myriad things makes to be most precious. "Holy Bible" said that the wisdom “is also more precious than the ruby”, is the priceless meaning. In ancient Sanskrit, ruby Italy is “king of the gem”.

But in China, is symbolizing many meanings red, at holidays, is presents relatives and friends' very good “the high quality goods”.VERTICAL CONSTRUCTION even if today, the ruby scaled height of burst quality's diamond is rarer and is precious. But the superior ruby is especially rare, 5 carat above extremely rare.

Affects its value is its color. The best quality goods may be red the dissimilarity which imagines with you; One kind is purely saturated the near deification color, does not have to be slightly brown and the blue color diffraction.

The high quality ruby's color is intense the coal which looks like blushes together, this is the most intense color which probably our ancestor can see. No wonder they the flame which this never extinguishes converge the charm.
