⚠️ Important Notice to the Gem & Jewelry Trade ⚠️

We have noticed that many people are misusing the Gemological Institute of America (GIA) logo on business cards, gemstone reports, and certificates.

❌ This is NOT allowed.

Even if someone has studied or graduated from Gemological Institute of America, it does NOT give permission to use the GIA logo for business purposes.

🎓 Once you graduate from Gemological Institute of America, you become a GIA Alumni Collective Member.
✔️ You can only use the official Alumni logo
✔️ And it must be used according to GIA guidelines and standards

🚫 Some local gem labs are using the GIA logo on their certificates to show they are “certified by GIA.”
This is false and strictly prohibited.

📌 Gemological Institute of America clearly states in its official website and documents:
• The GIA logo cannot be used without permission
• It cannot be used to promote personal or business services
• It cannot be used on gem reports or certificates unless issued by GIA

⚖️ This is misleading to customers and may lead to legal action.

🚨 If you see this kind of misuse in local gem reports:
👉 Please report immediately to Gemological Institute of America
👉 And also inform the GIA Alumni Association in Sri Lanka

🇱🇰 Sri Lanka has a GIA Alumni Association, and we are very concerned as a nation about this kind of wrong promotion and misleading practices in the gem trade.

🙏 We kindly request everyone in the industry:
• Use correct titles and qualifications
• Do not misuse logos
• Follow proper guidelines

Let’s keep the gem industry honest, professional, and trustworthy

🌍✨ Grandidierite – One of the Rarest Gemstones in the World

Grandidierite is an extremely rare blue-green gemstone, admired for its unique color and strong trichroism (showing three colors from different angles). First discovered in Madagascar, this gemstone is now also found in Sri Lanka.

💎 Most gem-quality stones are very small, and clean stones above 2–3 carats are exceptionally rare.

🏆 The largest recorded faceted Grandidierite in the world is around 764 carats, making it a true collector’s masterpiece.

📌 Due to its rarity, large transparent specimens are considered museum-grade gemstones and are highly valuable in the international gem trade.

🌿✨ Grandidierite – ලෝකයේ දුර්ලභම මැණික් ගල් අතරින් එකක්

Grandidierite කියන්නේ නීල-හරිත වර්ණයෙන් යුත් ඉතාම දුර්ලභ මැණික් ගලක්. විශේෂයෙන් කෝණය අනුව වර්ණ 3ක් පෙනීම (trichroism) මෙහි වැදගත් ලක්ෂණයක්.

💎 සාමාන්‍යයෙන් gem-quality ගල් ඉතා කුඩා වන අතර, 2–3 carats ඉක්මවන පැහැදිලි ගල් ඉතාම දුර්ලභයි.

🏆 ලෝකයේ වාර්තා වූ විශාලම faceted Grandidierite ගල 764 carats පමණ වන අතර, එය අගනා collector piece එකක් ලෙස සැලකේ.

📌 මෙවැනි විශාල සහ පැහැදිලි ගල් museum quality ලෙස සැලකෙන අතර, ජාත්‍යන්තර වෙළඳපොළේ ඉතාම වටිනා වේ.

Deeply saddened to hear the passing of Jeseel Haji, a great gem dealer from Beruwela. He was not only a respected figure in the gem trade, but also a kind and generous person who supported many in the industry, including myself and my business.

His loss is truly heartbreaking. May Allah grant him Jannah and eternal peace. Our thoughts and prayers are with his family during this difficult time.
