Heat Treated Citrine Crystal Polished Quartz Brazil Golden Orange Gemstone Specimen with Certificate of Authenticity

Description

Heat Treated Citrine Crystal from Brazil – Genuine Quartz Specimen

This beautiful Heat Treated Citrine crystal from Brazil is a genuine, natural quartz specimen that has undergone careful heating to produce its rich golden-orange colour. The specimen you see in the photographs is the exact piece you will receive, selected for its vibrant tones, structure, and polished finish. As with all our crystals, it comes complete with a Certificate of Authenticity confirming it as a 100% genuine mineral specimen sourced from Brazil. Heat-treated citrine, made from natural amethyst or smoky quartz, remains a highly popular and visually striking gemstone appreciated by collectors, decorators, and mineral enthusiasts.

Geological Background: Quartz Formation in Brazilian Environments

Citrine belongs to the quartz family, one of the most abundant and diverse mineral groups on Earth. This crystal originates in Brazil’s extensive quartz-bearing geological formations, which include pegmatite veins and hydrothermal deposits. These environments allow silica-rich fluids to cool slowly over long geological periods, forming large quartz crystals with hexagonal prismatic structures. The quartz used to create heat-treated citrine begins its life in these natural settings, developing internal clarity, fracture patterns, and characteristic growth lines.

Brazil is internationally recognised for producing high-quality quartz, and the country’s mineral-rich environments are uniquely suited to the formation of large, pure crystals. Over millions of years, geological processes such as volcanic activity, tectonic movement, and hydrothermal fluid circulation have contributed to the growth of quartz clusters that serve as the base material for heat-treated citrine.

Transformation into Heat Treated Citrine

Heat-treated citrine is created when natural amethyst or smoky quartz undergoes controlled heating that enhances or changes its colour. This process mimics natural geological conditions in which iron-bearing quartz crystals are exposed to high temperatures deep within the Earth’s crust. The heating alters iron impurities within the crystal lattice, resulting in the warm golden, honey, or amber tones characteristic of citrine.

The Brazilian quartz used for this transformation often displays pronounced internal zoning and natural structural features. After heating, these internal characteristics interact with light to create a bright, fiery glow unique to heat-treated specimens. The resulting colour distribution varies from deep amber at the base to lighter, glowing gold towards the tips or edges, highlighting the natural architecture of the quartz crystal.

Crystal Habit, Colour, and Mineralogical Features

This specimen retains the essential structural qualities of quartz: a trigonal crystal system, prismatic habit, and naturally occurring faces shaped by geological growth. Heat treatment brings out intense colour saturation, often accentuating the crystal’s termination points, ridges, and internal planes. Variations in colour intensity, small inclusions, and subtle fracture lines are typical features of genuine quartz and reflect the conditions under which the crystal originally formed.

The polished finish enhances clarity, allowing the golden hues to shine while revealing natural textures within the quartz. The combination of heat-induced colour and authentic crystal structure makes these specimens visually appealing and rich in mineralogical character.

Origin and Authenticity

Brazil remains the leading source of quartz suitable for both natural and heat-treated citrine. Its geological formations provide quartz crystals with optimal purity, internal consistency, and structural beauty. Your specimen has been carefully selected from these Brazilian deposits, ensuring a high-quality piece with vibrant colour and strong visual presence.

You will receive the exact crystal shown in the photographs, with full sizing visible in the images. Each specimen is individually chosen, and every purchase includes a Certificate of Authenticity confirming its genuine origin and mineral identity. This makes it an ideal choice for collectors, display, crystal enthusiasts, or anyone seeking a striking, naturally formed quartz crystal enhanced through traditional heat treatment.
