Facet Grade Alexandrite – Natural Colour Change Gemstone Rough

Discover facet grade alexandrite, a remarkable variety of chrysoberyl valued for its distinctive colour-changing effect under different lighting conditions. This rare gemstone attracts collectors, professional gem cutters and jewellery designers seeking exceptional natural gemstones.

What Makes Alexandrite Special?

Alexandrite is famous for its colour-change phenomenon. Depending on the gemstone, it may appear green or bluish-green in daylight and shift towards reddish-purple or purplish-red under incandescent lighting.

The strength and attractiveness of this colour change are important factors when evaluating alexandrite quality.

Characteristics of Facet Grade Alexandrite Rough

Facet grade alexandrite rough is natural crystal material considered suitable for cutting and polishing into finished gemstones.

Important characteristics include:

• Colour change: The strength and contrast of the colour shift under different light sources.
• Body colour: The attractiveness and saturation of the colours.
• Transparency: Clear material with good light transmission is desirable for faceting.
• Clarity: Inclusions and internal fractures affect cutting possibilities.
• Crystal weight: Original rough weight and potential finished carat weight.
• Cutting yield: The amount of usable material remaining after cutting.
• Mineral identification: Reliable gemological testing helps confirm natural chrysoberyl and distinguish it from imitations or other colour-change materials.

Alexandrite Rough for Custom Gemstone Cutting

Each alexandrite crystal requires individual evaluation before cutting. The cutter must consider its natural shape, colour distribution, inclusions and orientation to plan a suitable faceting design.

Possible finished shapes include oval, cushion, round, pear and other custom cuts, depending on the available rough material.

Factors Affecting Facet Grade Alexandrite Value

Alexandrite value depends on the strength of its colour change, body colour, clarity, carat weight, cutting quality, treatment status and verified geographic origin.

Natural alexandrite with a strong and attractive colour change can be particularly desirable. However, facet grade is a descriptive trade term rather than a formal universal quality certification.
