  • Gold or Silver for your Skin Tone

    A good example of a cool skin tone complimented by the right jewelry choice.

     

    Most people naturally have a preference for gold or silver–often for life. But certain skin tones are better suited for one metal over the other.

    First you need to identify whether you possess a warm or cool tone. This can be done easily enough by looking at the veins on the inside of your arm. If they are blue, you are probably tend toward a cooler skin tone. If the veins are predominantly green, you have a warm skin tone.

    So what metal and stone goes with your particular type? According to one source:

    Cool skin tones favor silver, platinum, and white gold. Stone colors for cool skin tones are pink, blue, purple, red, and magenta. Warm skin tones favor gold, pewter, brass, and copper. Compliment colors for warm tones are brown, green, orange, yellow, coral, and turquoise.

    Of course, fashion rules are occasionally meant to be broken. If you prefer gold and you’re of the cool skin tone variety, don’t let us stop you! What looks best on you is often what you like best.

  • Information regarding coating on SiC

    Excerpts from an email from Jay Neogi, Serenity Technology to C&C.

    <<Bob: As you know when Moissanite is slightly heated in air it has a tendency to form a thin layer of SiO2 (silicon dioxide) layer over the gem and since there is a huge RI (refractive index) mismatch between SiC (Moissanite) and the thin layer of SiO2 that forms, one will see this golden tone when the thickness of this SiO2 layer reaches few nanometer. It is an inherent behavior of Moissanite (SiC) material and this behavior is well documented in various technical journals. . . . . Please note: that golden tone is just the native SiO2 that forms on Moissanite and is falsely claimed by NAGL to be the color enhancement coating.

    Please see this technical article and there are numerous such reputed publications that you can find.>>

    ABSTRACT

    Amorphous and single-crystal α-SiC were exposed to various oxygen sources at room temperature. The oxygen sources included the residual gas in an ultrahigh vacuum environment, ambient air, ozone, and oxygen plasma. X-ray photoelectron spectroscopy (XPS) was used to follow changes in the surface composition and to determine the local bonding environment of the Si atoms. It was found that silicon oxycarbide species are formed when these SiC materials are initially exposed to oxygen. With extended exposure to ambient air, a SiO2 layer is subsequently formed over the silicon oxycarbide. However, the native oxide on the single-crystal SiC consists mainly of silicon oxycarbide species. The thicknesses of these native oxides were calculated using the XPS data. © 1997 American Vacuum Society.
