Vintage artisan made 14k yellow gold Atomic corundum ring

Vintage artisan made 14k yellow gold Atomic corundum ring. Such a cool unique ring - bright purple asymmetrical stone set in prongs with a unique, atomic style cut out on the sides. High hardness testing for stone. between 10-14k gold - given the color of the mark, I think it’s true 14k (at least 10k) with a copper rich mix that etches a bit - results in kind of an orange mark ultimately. Some kind of corundum - synthetic sapphire or spinel. Very very light yellow gold. Stamped 14k, size 8.75, 2.81g. 6040
