GiL Certified 15.14 ct Natural Untreated Blue Zircon SKU.1

Item InformationDimensions (mm)14.49 x 11.4 x 8.69mm

Weight (carats)15.14 carats

Colors

Certified Gemstone

No Treatment

Radiant zircon is the oldest known gemstone, with some crystals dating back 4 billion years, but also perhaps the most misunderstood. Unfortunately, due to the similarity of zircon’s name to the lab created diamond simulant cubic zirconia, many people don’t realize that zircon is a beautiful, naturally occurring stone with its own merits. Thanks to its tremendous fire and dispersion, it has been considered a less-expensive stand-in for diamond for many years, although zircon gives us many reasons to sing its praises and appreciate it in its own light.\

Treatment None (Permanent Color)

General Info:

A brilliantly transparent gem, sphene has fire greater than that of diamond! This gem is named from the Greek word for “wedge,” as its crystals are typically wedge shaped, but may be referred to by its mineral name, titanite. Another characteristic sphene possesses is birefringence, or double refraction, meaning that light splits into two rays as it passes through the gem. As a result, the back facets appear as double images, giving the gem a soft, hazy appearance, similar to the doubling seen in zircon.
