Blue Zircon Oval Faceted Stones, AA Grade


This AA-grade oval faceted zircon stone features an attractive shade of light blue and would be an excellent choice for pendants, necklaces and earrings. Use the stone by itself for simple designs, or highlight the subtle color by pairing it with contrasting-color stones in more complex pieces. Blue zircon is one of the birthstones for December.

Zircon is a hard, naturally occurring gem mineral. Faceted zircon has a brilliance that rivals a diamond, making it an economical alternative. Most natural zircons are brownish orange; heat enhancement results in yellow, gray, green, red, blue or colorless stones. In the Middle Ages it was believed to protect against evil spirits, improve sleep and cultivate honor, wisdom and wealth.

The oval cut is an even, symmetrical shape but elongated. The arrangement of its facets is similar to that of a round brilliant, designed to maximize light and color.
