Technical

- With no cleavage and hardness of 6.5 - 7 on Mohs scale, Chrysoprase makes an excellent gemstone for jewellery.
- Its specific gravity ranges between 2.65 - 2.90. This measures the density compared to water. Stones with higher specific gravity tend to be more vibrant and flawless.
- High quality Chrysoprase will be highly translucent, untreated and unaffected showing no cracks, fissures or inclusions, the colour should be evenly distributed.
- Chrysoprase has a unique ability to reflect and refract rays of light in a way that makes the stone glow as if it were alive.
Chrysoprase vs Jade: Distinguishing Two Green Gems
Chrysoprase and jade are distinct green gemstones often confused due to their colour.
Each possess their own unique characteristics. Chrysoprase, a variety of quartz, dazzles with its apple-green hues as a result of nickel content. Jade, encompassing both nephrite and jadeite, offers different green shades and occasionally surprises with colours like lavender or yellow.
The formation of these gemstones also differs. Chrysoprase forms in weathered nickel-rich serpentine rocks, while jade forms under high-pressure, low-temperature metamorphic conditions. This difference in formation contributes to their unique textures - chrysoprase typically has a smoother, more uniform appearance, while jade, especially nephrite, can have a more fibrous structure.
While both stones are prized for their beauty, their rarity and value can vary. High-quality Chrysoprase is appreciated for its vivid colour, rarity and smooth texture. Chrysoprase has been highly valued in Western cultures, particularly in ancient Greece and Rome, and throughout medieval Europe.
