The most vivid teal colored lab gemstones are lab garnets. YB:YAG comes in an array of shades of blue / green to green / blue. Yb:YAG is often referred to in the trade as "paraiba" YAG and even sometimes labeled incorrectly as "paraiba sapphire." A windex colored YB:YAG is grown in large quantities for the gem trade. We offer that "windex" color trade material, but also a collection of different industrial Yb:YAG variations, each unique, with shades and intensities of teal. We only offer czochralski grown YB:YAG.
