Sugilite is a relatively rare pink to purple cyclosilicate mineral. The mineral is also referred to as lavulite, luvulite, and royal azel by gem and mineral collectors. Zambia has many rich sugilite deposits and unfortunately it is often illegally mined. Two types of sugilite occur in the country, Massive sugilite and Gel sugilite. Massive Sugilite is the most common type found in Zambia and is characterized by its dense, opaque appearance. It typically ranges in color from deep purple to violet. This variety is not considered gem-quality due to its lack of transparency but is highly sought after by mineral collectors due to its rarity and distinct characteristics.

Gel Sugilite is a much rarer and more valuable form found in limited locations. It has a translucent to transparent appearance with a vibrant purple to lavender color and a gel-like consistency. This variety is highly prized for its gem-quality and used in exquisite jewelry pieces due to its exceptional beauty and rarity. However, recent years have seen a significant decline in specimen-grade gel sugilite, making it even more valuable to collectors.
