Morganite Quality Factors

Mention of the name morganite immediately brings to mind beautiful pastels of pink, purplish pink, and orangy pink. - Robert Weldon, courtesy Mayer & Watt, Maysville, Kentucky
Morganite is known primarily as a pastel-colored gem in light, soft shades of pink, purplish pink, and orangy pink. Although light tones are normal for morganite, some stones display strong color.

Morganite’s color range includes pink, rose, peach, and salmon. In today’s market, the pink and rose tints are more fashionable. The peach and salmon hues seem less popular, but some collectors value untreated peach-colored material more highly than heat-treated pink stones.

The gem is almost always heat-treated to improve the pink color. The treatment is not detectable. Heat drives off the yellow or orange tinge, leaving a purer and more attractive pink. The resulting color is stable and won’t fade.

Because morganite has distinct pleochroism—pale pink and a deeper bluish pink—it’s necessary to orient the rough carefully for fashioning. Strong hues in morganite are rare, and gems usually have to be fairly large to achieve the finest color. Morganite is cut in all standard shapes and sizes as well as in unique designer cuts.
