Most collectors will encounter Montebrasite only occasionally. A parcel of this size, quality, and consistency is considerably rarer. Fine Montebrasite has always been difficult to source, and obtaining a collection of clean stones requires the selection and cutting of a substantial amount of rough, with only a small percentage meeting the standard seen here.
This collector-grade lot consists of 88 untreated Montebrasite gemstones from Brazil with a combined weight of 41.88 carats. Displaying a beautiful Baby Yellow color, the parcel contains a mixture of shapes and sizes ranging from flawless to eye-clean clarity. Rather than a matched set, this is a carefully selected collection that showcases the quality and character of one of the rarest gemstone species available to collectors today.
The appeal of this parcel extends beyond rarity alone. The combination of attractive Baby Yellow color, exceptional clarity, and natural untreated status is rarely encountered in quantity, making opportunities such as this increasingly difficult to replace once sold.
It is not about what it costs. It is about what it costs to find another like it.
The most remarkable recent development in montebrasite color documentation is the blue material from the Buranga pegmatite near Gatumba, Rwanda, formally documented by GIA researchers Wim Vertriest and Gil Yuda in Gems & Gemology Winter 2023. Learn more about Montebrasite.
