A rare bicolour beryl from Minas Gerais, Brazil, combining fine aquamarine with clear white beryl in a single crystal. The transition between the two is natural and distinct, creating a striking contrast between soft blue and colourless clarity. Known as Alpine Aquamarine, this material has been found only once, with a very limited parcel available. Each stone is inherently individual, defined by the balance and movement between the two zones. An unusual and collectable gemstone, valued for its rarity as much as its quiet visual interest.
