Just as the wool is dyed, the brown leather and wood furniture is stained and sealed, many of the colored gemstones on the market today have been treated to enhance their natural beauty and durability, baby music and to make a wider variety of jewelry quality gemstones available and affordable. A treated gemstone is still a real diamond created by nature and its forces. Some of the most common treatments used today as heating stones to enhance their color, have been used for centuries to finish what nature started. Without heat treatment, there would be no bright blue topaz, would the intense blue-violet of Tanzanite be a dull brown, and most rubies and sapphires would have a less-than-vibrant hue. Your great, grandmother sapphire brooch may have been tempered way back in 1800! Most jewelers sell processed goods. The practice baby music is ethical as long as the treatments are given, and their degree of permanence taken into account when pricing the gem. Below are ten treatments that require action by the Federal baby music Trade Commission: Bleaching Chemicals baby music as hydrogen peroxide, baby music diluted acid or chlorine are used to lighten or remove color or stains. Lotions and skin oils can sometimes stain bleached stones. Oven Filling: Fillers such as glass or plastics baby music are used to seal holes or pits on the surface of a bead. Cavity filling is sometimes used to emphasize too. Heat from a light microscope, a jeweler's torch, shop lighting, baby music or even sunlight can cause fillers to leak. Colorless Impregnation: Molten wax or plastic is used to fill the pores in a bead, then allowed to solidify in order to improve the pearl color, and forms a protective seal. The heat can kill the seal. Dyeing Chemicals or colored oils used to add color or to deepen baby music it. Dyes can fade in sunlight. Fracture Filling: Like the cavity filling, fracture filling used to seal narrow baby music fracture of stone to improve its clarity. Most often colorless glass, plastic, or oils are used as fillers. Temperature can cause fillers to leak. Heat Treatment: Heat is the oldest gem therapy, and the most common. Today it is becoming baby music quite science: depending on the temperature used and the length and degree of heating and cooling, the color may be lighter, darker, deeper, or changed completely. Heat-treating is very durable, but the intense heat from a jeweler's torch can destroy it. Irradiation: Scientists began experimenting with gem radiation as early as the 1900s. The process of irradiation arrange a stone's throw atoms and electrons to change the color. The new color is not always stable, though. Exposure to heat or even daylight is sometimes enough to fade color. Lattice Diffusion: By combining extremely high temperatures, chemicals, bright jewels can be applied to a shallow layer of almost any color. Lattice diffusion can also improve asterism-star of the star ruby or sapphire. Sugar and Smoke Treatments: These simple surface treatments can darken pale opal and enhance its color. If the stone is soaked in a hot sugar solution or roasted over a fire, the result is the same. Surface Modifications: Bonding various backing, such as foil, fabrics, or even spring underneath the stones can enhance color or provide color where there was none. Coatings such as wax or varnish bring out the luster of porous stones. Painting is also used to improve a pearl color. A small dab of nail polish baby music on the underside of a pearl can provide a reasonable colorless bead appearance of a ruby. Here is a shortlist of the most common treatments for popular gemstones. , Amethyst: heat treatment; Aquamarine: heat treatment; Chalcedony: dyeing, Citrine: heat treatment, Emerald: fracture filling, dyeing, Jade: impregnation, bleaching and impregnation, dyeing, Lapis Lazuli: dyeing, coating, Opal: impregnation (oil, wax, plastic ), sugar processing, smoke treatment; baby music Pearl: bleaching; Ruby: heat treatment, lattice scattering, fracture filling, cavity filling; Sapphire: heat treatment, lattice baby music scattering, fracture filling, cavity filling, Tanzanite: heat treatment; Topaz: heat treatment, followed irradiation heat treatment , Tourmaline: heat treatment, irradiation, Turquoise: impregnation (wax, plastic, dyes); Zircon: heat treatment Some treatments, such as heat and radiation is undetectable even by gemologists, so be careful: Suppose a colored gemstone is treated baby music until proven otherwise.
