Faceted Tourmaline Price Factors

Color: Color of Tourmaline is natural or heated. Heat treatment will lower the price than the natural. Light color tourmaline has less inclusion but they are very less liked by the buyer. Dark tourmaline stones have more inclusions especially in case of rubilite tourmaline. The inclusions give dark color to the stones. They are often replaced with rubies.

Cut: Cut of Tourmaline in loose stone matters a lot. If the cutting is excellent and there is no window, it will give brilliance to the tourmaline. Poor cutting lower down the value of a stone.

Clarity of stone is the third factor. The more the stone will be clean, the more its price will be higher. Dark color with minimum or less inclusions will be more ideal for buyers than the light color with less inclusions. Some buyers preference to have inclusions for their being close to the natural. Red and pink tourmaline inclusions are more visible and they are also the most desired tourmaline stones than the other colors despite less clarity. In faceted stones, buyer prefer eye clean to loupe clean stones.

Size Carat Weight: Bigger tourmaline stone will have more value and expensive than the low weight stone. For example, 1 carat tourmaline price will be less than 10 carat size stone. 

Shapes: Shape of Tourmaline Cut Stone:  The long shape of tourmaline crystals give the idea to the final gem's shape and size while leading to many narrow sizes. Tourmaline buyers prefer to buy standard sizes because they are easier to fit into standard gems jewelry settings.
