Songea Red Round Unheated Untreated Sapphire 0.65carats 5mm

Songea Red Round Unheated Untreated Sapphire 0.65carats 5mm

$58.00

This is a fine round we had specially cut for us from a friend in Tanzania. Fine deep burgundy red color with lots of sparkle that the Songea rubies and sapphires are synonymous with.
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.
