Prasiolite Pendant Value Guide

This striking rectangular prasiolite pendant represents a classic era of Brazilian gemstone jewelry from 1970-1990. Known as green amethyst, its delicate leek-green hue and elegant sterling silver setting make it a highly sought-after specimen for quartz collectors.

What affects the value of Prasiolite Pendant?

• The clarity and saturation of the green hue significantly impact the $150-$165 price range.
• The overall condition of the sterling silver setting, including the absence of deep scratches or tarnish.
• The precision of the rectangular facet cuts and the symmetry of the gemstone's proportions.
• The provenance of the piece as a mid-to-late 20th-century Brazilian export.

How to Identify Prasiolite Pendant?

• Verify the distinct rectangular step-cut or emerald-cut common in 1970s-1990s Brazilian prasiolite settings.
• Check for the '925' or 'Sterling' hallmark on the silver mount to confirm the metal purity.
• Inspect the gemstone for a pale, translucent green color characteristic of heat-treated amethyst from the Montezuma mine.
• Look for minor natural inclusions under magnification that distinguish genuine quartz from green glass imitations.

History of Prasiolite Pendant

Prasiolite, also known as green amethyst, is a beautiful quartz variety. While some prasiolite occurs naturally, much of the material seen in jewelry is heat-treated amethyst. The practice of heat-treating amethyst to achieve this delicate green hue dates back to the early 20th century. Its subtle color makes it a popular choice for elegant jewelry pieces.
