Gorgeous rare RED TOPAZ Gemstone measures 7.05 x 4.70mm and weighs .80 carats. Hand cut in our Tolpa design studio using the "Marquise del grillo" cut to maximize the red in the host gem (see pics). Red is one of the most sought-after topaz colors and represents less than one-half of 1 percent of facet-grade material found. The color the trade calls imperial topaz is highly prized and very rare. Many dealers insist that a stone must show a reddish pleochroic color to be called imperial topaz. Refractive index tested for authenticity. Natural and untreated gem. Shipped promptly, fully insured and giftboxed. We use PayPal for payment and shipping.
