The ZULTGEMS name is your guarantee that each gem is cut by some of the world’s most experienced lapidaries to optimal proportions.
Zultanite® tests the skills of even the most experienced lapidaries due to its very low yield (2 percent), tendency to cleave, or split apart, in a single direction (much like a Diamond) and its trickier-than-usual crystal orientation. Most Zultanite® rough yields the popular jewelry sizes of one to three carat gemstones. Sizes exceeding 5 carats are exceptionally rare. A wide variety of classic and specialty cuts are available.
Some Zultanite® even displays the coveted cat’s eye effect. The cat’s eye effect, also known as chatoyancy, appears as a single bright reflective line of light, similar to a cat’s eye. This optical effect is created by the reflection of light from long needle-shaped inclusions occurring in a parallel arrangement. Similar to star gems, the cat’s eye effect is dependent on a gem being cut ‘en cabochon’ and is most visible in a direct, single beam of light. Sporting a phenomenal dual effect (color change + chatoyancy), these Zultanite® varieties are exceedingly rare.
