Synthetic Corundum Rough – Varied Green-Blue Chunks with Cracks (Special Purchase)

This is a limited batch of synthetic corundum rough featuring a captivating mix of green and blue tones, with color variation that closely resembles our #85 Tourmaline Green Cracked listing—but with a cooler, slightly more vibrant palette.

• Color: Varied green with hints of teal and blue; visually dynamic under different lighting.
• Sold in chunks and broken pieces.
• Material: Lab-grown corundum with a unique fracture pattern—ideal for faceting, cabbing, or collectors who appreciate raw beauty.
• Availability: Special purchase—this material is not part of our regular inventory and likely won’t be restocked once sold out.

If you liked #85, you’ll love this batch for its added color complexity and one-of-a-kind look. Perfect for artists and lapidaries who embrace the unexpected.

If you would like to see additional pictures of the piece(s) you would like, please feel free to contact me and I will be happy to provide additional pictures for you to review.
