Madagascar Alexandrite Rough for Gem Cutting

Natural alexandrite rough is highly interesting for experienced gem cutters because its colour-changing effect can create distinctive faceted gemstones.

Each rough crystal should be carefully examined for colour-change strength, transparency, internal fractures, crystal dimensions and potential finished gemstone yield.

Suitable material may be fashioned into oval, cushion, round, pear or custom-cut alexandrite gemstones. The cutting orientation is particularly important for displaying the best possible colour change.

Evaluating Madagascar Alexandrite Rough Quality

The value of Madagascar alexandrite rough depends on several important factors:

• Strength and quality of the colour change
• Natural colour under daylight and incandescent lighting
• Carat weight and crystal dimensions
• Transparency and clarity
• Internal inclusions and fractures
• Potential finished gemstone weight
• Verified geographical origin and treatment status

Independent gem laboratory testing can help confirm alexandrite identity, assess colour-change characteristics and establish detectable treatments.
