Natural Alexandrite & Diamond Ring. Photo MS Rau Antique

A stunning 1.41-carat natural Alexandrite sparkles in this beautiful ring. Changing from a violet shade to olive green, this rare stone is surrounded by .77 total carats of round brilliant white diamonds, and all are set into a ravishing 18K white gold filigree setting. An intriguing stone with a noble history, Alexandrite is one of the most valuable gemstones in the world. Its most unique property is the spectacular change of color. This color change depends on the stone's reaction to different types of light. It displays a lovely greenish hue in daylight, and a beautiful purplish-red color in incandescent light. The first Alexandrite was discovered in Russia in 1834 on the birthday of Czar Alexander II. The czar claimed all subsequent finds of this natural chrysoberyl, making this truly the gemstone of royalty. Price Upon Request

Ludovisi Ares, Roman after the Greek original from ca. 320 BC.

Some restorations were made to the sculpture by Gianlorenzo Bernini in 1622. 

This remarkable sculpture was rediscovered in 1622, on the site which was once apparently the temple of Mars, of which very few traces remain today. It was recovered near the more distinguishable site of the church of San Salvatore in Campo, which Pietro Santi Bartoli recorded as been found during the digging of a drain.
