Tourmaline comes in the widest color range of any gem, from vivid pinks and greens to the famous watermelon slices. Color, saturation and clarity drive its value.
With tourmaline, the specific color and its saturation matter most; some varieties are far rarer than others.
Vivid pink to red tourmaline that stays saturated in any light; the most valuable of the common colors.
From olive to vivid emerald-green; chrome tourmaline rivals tsavorite in color at lower cost.
Pink-and-green zoning, often cut in slices. Prized for clean, well-defined color boundaries.
Six main criteria determine the price per carat. It is their combination that sets the final value.
The dominant factor. Vivid, saturated colors (especially clean pink-red rubellite and intense green) command the most; muddy or pale tones far less.
Brazil (notably Paraíba) and Mozambique lead; Afghanistan and Nigeria supply fine pinks and greens.
Some tourmaline is heated to lighten or improve color; this is common and stable. Untreated vivid stones are preferred.
Pink/red rubellite often shows inclusions and is accepted slightly included; greens and blues are expected cleaner.
Price per carat rises sharply with size: fine large stones are rare, so they are proportionally far more expensive.
A report from a recognized lab (GIA, SSEF, Gübelin, GRS, AGL) confirms identity, origin and treatment, securing the valuation and resale.
Tourmaline's appeal is its color diversity, but value concentrates in vivid, pure hues with strong saturation.
Open, lively stones with good transparency are worth far more than dark or greyish ones.
Common greens and pinks are affordable; rubellite, chrome green and bi-color stones cost more.
The neon Paraíba variety is in a class of its own and is covered on a dedicated page.
Geographic origin can be a strong prestige marker that weighs on value.
