The object in the image is a blue glass vase, possibly the Baccarat Crystal Mosaïque Tumbler or the Iitalla Leia #2785 Cobalt Blue and Clear Cased Vase designed by Tina Nordstom. The vase features a sleek silhouette and an intense cobalt blue color. It measures approximately 5.25 inches in diameter and 8.5 inches in height. The vase is made of lead crystal and has a clear glass base that extends partially up its sides. It is described as being in flawless condition, with a bold color reminiscent of the Mediterranean. Cobalt blue glass is made by including a cobalt compound in a glass melt, resulting in a deep blue color. The color is intense, requiring only a small amount of cobalt to achieve a noticeable effect.
