Blue sapphire
Look for a pleasing balance of hue, tone, and saturation. Very dark blue is not automatically better; the stone should remain attractive in ordinary lighting.

A sapphire for your style
Sapphires come in many shapes and cutting styles, not just one outline. Compare color in more than one type of light, then look at transparency, proportions, and overall brightness.

Choosing your sapphire
Pink sapphire
Soft pink through stronger pink shades offer different moods. Color intensity, clarity, size, and treatment can all affect value.
Yellow sapphire
Yellow sapphire is a distinct color choice. It should not automatically be described as padparadscha.
Padparadscha sapphire
This rare designation refers to a delicate pink-and-orange color range. Ask for independent documentation rather than relying on a trade name alone.

Treatments and reports
Not all sapphires require heat treatment. Untreated and treated stones are available, and heat, diffusion, and fracture filling are different processes. Ask for disclosure and consider an independent report for an important purchase.

Care
Sapphire has good durability for jewelry, but treatments can change its care requirements. Warm, soapy water is suitable for many untreated and heat-treated stones. Fracture-filled or dyed material should be cleaned with a damp cloth. Confirm suitability before using ultrasonic or steam cleaners.
