The other notable sale was a rare antique Renaissance Revival suite of sapphire, demantoid garnet and enamel jewelry attributed to Louis Comfort Tiffany for Tiffany & Co Tiffany & Co., circa 1920.

The hardness is only 6.5, or lower even than that of quartz—a character rather adverse to the use of demantoid as a gem.

The green garnet that is called "olivine" in the trade also approaches diamond in luster, hence the name "demantoid," or diamond like, sometimes applied to it.

It sits within a scrolling frame suspending a flexible swag, accented by circular and oval-cut demantoid garnets and sapphires, highlighted by enamel floral sprays and suspended from a chain of floral links.

As was explained under garnet, jewelers frequently use the term "olivine" to designate demantoid garnet.
