Vintage Native American Sterling Gemstone Ring, Southwestern Ring

Vintage Sterling Silver Gemstone e Ring Size 8.5 Very unique handcrafted vintage ring with Southwestern Style. I believe this was made by a Native American artist (its signed either SMH or HWS) but I have not been able to attribute it to anyone Sterling silver, marked and tested Abstract, southwestern stylized frame Rectangular reddish brown stone with white inclusions - I believe this is red jasper with white quartz. I am not a stone expert, but Im happy to answer any questions Fits size 8.5 Measures .75" tall and weighs 5.7 grams In very good vintage condition, only minor signs of wear appropriate to its age.
