A brief description of the color types for ruby and sapphire used at Lotus Gemology.

A loving look at ruby – the gem of passion – from the standpoint of the connoisseur.

World auction records for ruby, sapphire and spinel.

Since the turn of the millennium, the price of fine spinel has risen at an incredible pace. No longer simply the poor man's ruby, spinel is finally getting the attention it deserves as one of the world's premier gems.

To the jeweler, spinel is famous for its vivid colors. But for the gemologist, this gem is unlike any other. Its extreme hardness allows a fine polish. Couple this with single refraction, which eliminates the image blurring found in most other gems, and a varied landscape of inclusion subjects, and the result is an unparalleled canvas of delight for the photomicrographic artist.
