Tanzanite

• Color: The most valued tanzanites display deep, saturated blue or violet-blue hues; lighter shades are more common and affordable.
• Clarity: High-quality stones are generally eye-clean. Inclusions can slightly affect transparency but rarely color.
• Cut: Faceted shapes like oval and cushion maximize brilliance and pleochroism (blue–violet–burgundy tones).
• Carat: Stones over 5 carats show stronger pleochroism and color depth; very large clean stones are rare.
• Treatment: Nearly all tanzanite is heat-treated to produce or stabilize the blue-violet color — a standard, permanent enhancement.

• Clean gently with warm water, mild soap, and a soft brush.
• Avoid ultrasonic or steam cleaners — tanzanite has distinct cleavage and can crack under sudden temperature changes.
• Store separately from harder gems like sapphires or diamonds to prevent scratches.
