Appreciate help with identifying maker of bracelet & Value signed "L H": inlay, cabachon, tufa

Weight is 85 grams, the center stone is 1" x 1/2", could not identify it. There are 12 small triangle inlays of what appears to be Sleeping Beauty turquoise? Has artist hallmark, LH, on the inside along with the sterling stamp. Inherited it from my deceased aunt but am not sure if this was made by a Navajo or Zuni silversmith? It is a nice contemporary? piece but I would like to know more about the age, silversmith and the stones used in this bracelet.
