Located in New York, NY
Opal Tsehay Mewcha, Wegeltena, Delanta Woreda, South Wollo Zone, Amhara Region, Ethiopia Measures: 14.4 cm tall x 11 cm wide Precious opals are a hydrated amorphous form of silica (amorphous meaning a non-crystallized solid), unlike crystalline forms of silica, which are classed as minerals. Australia is the locality most associated with precious opal. The precious opals of Ethiopia were only discovered recently in 2008. Opals are formed over thousands of years when rain frees spherical silica particles from sandstone. These microscopic particles spread deep into underground cavities and are then compressed into a closely-packed interlaced structure. When miners bring them forth from the earth to the surface, sunlight travels through this microstructure creating the dazzling kaleidoscope of flashing rainbow colors that we see here. This opal may be unique. The colors are like no other we have seen from Ethiopia. There are several names given to opal (Black Opal, Boulder Opal, Fire opal, etc.). This piece begins an entirely new genre - Candy Opal.

Antique Lion Figures French Creamware 18th Century
Located in Katonah, NY
We are thrilled to offer this exceptional pair of creamware lions, each elegantly resting on a tall base adorned with sumptuous swags of dark blue "curtains" with gleaming yellow tassels and trim. Crafted in France, these figures are unparalleled and truly a masterpiece of 18th-century creamware. They date back to the late 18th century, circa 1790. Each lion's head and mane is exquisitely painted with vibrant yellow and lined in striking midnight brown. Their mouths are painted in delicate pink, adding an extra touch of charm. Not only are these lions a sight to behold, but they will also bring a touch of humor to your home. Their jovial expressions make it impossible not to laugh along with them.

Placed on a mantel, they would undoubtedly be the focal point of any room, commanding attention, and admiration from all who see them. These lions are genuinely a one-of-a-kind treasure that is not to be missed.

Creamware was first produced in England sometime before 1740. Foremost of the pioneers of creamware in the Staffordshire Potteries was Thomas Whieldon. The young Josiah Wedgwood partnered with Thomas Whieldon from 1754-1759. When Wedgwood left to set up his own business, he immediately directed his efforts to developing creamware. Around the same time, in the mid-18th century, French potters developed their creamware known in France as "Faience Fine...
