Raw Chrysoprase Value Guide

Raw Chrysoprase is a prized cryptocrystalline variety of silica, distinguished by its vibrant apple-green hue derived from nickel impurities. This Australian-sourced gemstone carries a rich legacy, having been favored for Roman signet rings and Victorian-era ornamental jewelry.

What affects the value of Raw Chrysoprase?

• Intensity of the green color, with deeper and more uniform saturation commanding higher prices.
• The size and weight of the rough specimen, typically valued between $25 and $40 for standard collector pieces.
• Translucency levels, where semi-transparent sections are more desirable than completely opaque material.
• The presence of host rock or matrix, which can either add character or detract from the pure gemstone weight.

How to Identify Raw Chrysoprase?

• Look for the signature 'leek-green' or apple-green color which distinguishes it from other green chalcedony.
• Examine the specimen for a waxy or vitreous luster typical of unpolished silica and quartz compositions.
• Check for a cryptocrystalline structure that lacks the visible crystal faces found in emeralds or peridot.
• Verify the origin as Australian, as these specimens are renowned for their superior color saturation and quality.

History of Raw Chrysoprase

Chrysoprase, a green variety of chalcedony, has been used since ancient times for decorative purposes. Its name is derived from the Greek words 'chrysos' meaning gold and 'prason' meaning leek, referring to its distinctive apple-green color. It was particularly popular in the Roman Empire for seals and signet rings and experienced a resurgence in popularity during the Victorian era for jewelry and ornamental objects. Today, it remains a sought-after gemstone for its vibrant color and smooth texture.
