Medallion or red carved item seems to me as a focal point for something else.
Very red. Jade comes in various colors but rarely in red if red Jade [Keep].
Never sell.
Red jade — symbolic.
Personally I suggest getting a Presidium II tester will run nearly $500 but worth the money. Tells you conductivity of material to the material type present. Follow instruction in owners instructions included in purchase and will guide you toward material matching type.
Other machines can provide additional clarification of type, reflectometer provides spectral feedback upon gem light penetration which matches materials to the exact frequencies derived upon light penetration not as expensive as prior mentioned device except oil required to determine costs $100 per bottle and you get a half bottle upon purchase. Worthwhile purchases. If you can afford to acquire. Remember identification of material is more valuable the longer your doing these types of transactions. Maybe we do not buy exactly what was sold but we could determine to our best ability the actual type before we sell or keep or give away as gifts. Teaching others is a valued gift. Even if no respect is given eventually provides value later when others follow your efforts. Focus on correcting industry failures. Industry my great grandfather left me is full of failures. It is time I deal with issues head on.
