Description
Description
This 5.13 carat natural sphalerite originates from Spain and displays a warm orange-red hue, cut into a rectangular fancy emerald shape measuring 11.40 × 6.80 × 5.40 mm. With VS clarity, the gemstone shows good transparency and brilliance, enhanced by its untreated and natural origin. While the stone’s color appears highly saturated in photos, in reality it is slightly softer, giving it a refined and balanced look. Sphalerite is renowned for its exceptional dispersion—greater than that of diamond—producing remarkable fire and vivid flashes of color. Due to its relatively low hardness, sphalerite is best suited for collector’s stones or for bespoke statement jewelry intended for occasional wear.

Production & Certification
Production & Certification
Every Sosna Gems gemstone undergoes careful expert inspection before shipping and is delivered in a tamper-proof Gemstone Security Seal to protect its authenticity and origin.
Each piece includes an authenticity certificate, confirming its natural origin, authenticity, and key gemological characteristics – weight, cut, color, and clarity.
Some gemstones in our collection already come with a valid certificate from an international gemological laboratory– such as GIA, IGI, or another globally recognized institution.
These gemstones are clearly marked in our catalog and ready for immediate dispatch.
If you wish, we can arrange independent laboratory certification for other gemstones as well – either before or anytime after purchase.
Our gemologists will be happy to assist you in choosing the most suitable laboratory and explain the entire process.
