Captivating 18.37ct Oregon Sunstone Intaglio

You've seen Oregon Sunstone before,  but have you seen an Oregon Sun stone? 
The intaglio carving weighs 18.37ct and measures 27.2x18.8x4mm.  
The stone is a red/orange and green dichroic with a beautiful shiller pattern across the face.  This stone is a dazzling one. 
This needs to go into a custom designed pendant or necklace for a high-end custom piece. Retail on this stone is well over $5000, so this is also a great investment as it's sure to gain in value.
