This treatment is a common standard practice in the gemstone trade. The addition of oil or resin serves to increase the stone’s stability during the cutting and polishing stages. The treatment is reversible at any time. Aquamarine is commonly heated to enhance its color. Currently, there is no scientific method to determine whether or not this stone has undergone any enhancement treatments. Weights and dimensions are approximate.
