This gorgeous purple sapphire displays stunning color and brilliance that emits electric flashes of blue, purple and pink. The sapphire ranges in color from a rich velvety purple to a color that is very similar to the rich periwinkle color of fine quality tanzanite. The sapphire is 4.7 mm round and is uniquely and beautifully presented and mounted with three bezel set round brilliant diamonds which are SI2 GH quality (bright, white, eye-clean and brilliant).
In total the pendant has 0.56 carats of fine quality sapphire and diamonds and is made with 14K white gold. A large bail has been placed on the pendant so that it may accommodate a variety of chains. This magnificent piece was designed by Jill Underhill of Color Symphony (http://www.colorsymphony.com) and will be shipped directly from their location in New Hampshire.
This gemstone (or gemstone that is part of this piece of gemstone jewelry) has been enhanced by traditional heat treatment. Traditional heat treatment is used to improve a stones color, remove color zoning/banding, and improve clarity. This treatment is considered permanent. The only way to tell if a colored stone has been treated is for the stone to be analyzed by a lab. Generally only gemstone laboratories have the equipment necessary to make a qualified judgement with any certainty.
Untreated gemstones are rare and should be verified by a lab independent of the seller. A good rule of thumb is to always assume a gemstone has been enhanced, unless valid certification from a reputable laboratory is available. No one that sells jewelry or gems should be doing appraisals, certifications, or analysis. It should always be an independent third party with no vested interest in the sale.
