About Us

Rohr Jewelry was established in 1951 by Alfred J Rohr in the city of Hays, Kansas. Al began as a watch repairman and moved into other areas of sales in coming years. Current owner Michael Rohr (son of Alfred Rohr) grew up in the jewelry business starting with minor jewelry repairs and clocks. Michael and his wife Susan, purchased Hankins Jewelers in Newton in 1991, and changed the name to Rohr Jewelry shortly thereafter.

Rohr Jewelry has always had a strong emphasis on, and taken pride, in being well trained in sales, service work and a strong custom work background. We are able to compete with anyone in the jewelry business because of our efforts to buy right and sell right. We have diamonds that we can sell for much less than the internets #1 diamond company.

Product Knowledge


The word diamond comes from the Greek, “Adamas,” or Latin’s “Diamas,” both of which means unconquerable. The fact that diamonds are almost indestructible makes them the perfect symbol of everlasting love. The Greeks believed that the fire of a diamond reflected the constant flame of love.


“A Diamond is a natural mineral consisting essentially of pure carbon crystallized with a cubic structure in the isometric system. Its hardness in the Moh’s scale is 10; its specific gravity is approximately 3.52; it has a refractive index of 2,42 and it can be found in many colours.” Definition supplied by the DTC.

A gemstone of this description that has been mined from the earth is the only gem that can be called a Diamond. The term “cultured” is not acceptable in conjunction with “diamond.”


Very simple in composition: C carbon---99.95%. Diamond is the only inorganic gemstone that consists of only one element Chemically its simple carbon. Its crystal form gives it three desirable optical properties:

  • Hardest gemstone known to man. Diamond’s hardness enables it to accept a higher polish than any other gemstone, thereby making it more brilliant than any other gemstone.
  • Melting point is 6,900 degrees F -4,000 degrees C – 2 1/2 times the melting point of steel.
  • Does not undergo thermal expansion (water to ice). Four times more reflective than glass
