The vast majority of commercial Citrine is actually lower-quality Amethyst that has been heated to turn the crystals yellow. Gemisphere’s handcrafted, near-flawless necklaces are true, natural Citrine with luminous yellow to golden-yellow color and without the brown tinge commonly seen in Citrine. Therapeutic Quality Citrine Only pure-yellow Citrine can draw the yellow ray to the body. The color of therapeutic Citrine ranges from light to deep yellow and sometimes possesses a golden glow. Very pale Citrine does not manifest yellow-ray energy strongly enough to produce therapeutic effects. Dark-amber or brownish Citrine can actually be detrimental, because it muddies the energy flow to the atoms, molecules, cells, and organs that are dependent on the yellow ray for life. Indeed, any degree of black or brown within Citrine is a toxic contaminant. Internal flaws dull Citrine's appearance and diminish its ability to express the yellow ray. Slight surface flaws are acceptable, as are a very small number of internal cracks, but only if they occur in Citrine that is pure, bright yellow. Ideal Citrine is flawless and the true yellow of the rainbow. Citrine that displays the special optical property known as gem candescence radiates a greatly enhanced flow of Citrine energy. Our Citrine Necklaces Our therapeutic Citrine necklaces are made with Citrine rounded chips that have been cut from the highest quality crystals, usually reserved for making faceted gems. Once we have cut the individual chips, we tumble and polish them to reveal their exceptional gem candescence, a brilliant liquid quality found only in superior quality gemstones. Citrine necklaces of this high quality are available only from Gemisphere.
