The Hileman Collection features exquisite Australian opal jewelry designs by Mark Hileman.  Our opal inlay jewelry is a combination of the finest opal Australia has to offer paired with expert craftsmanship.  Mark has been designing and creating inlay jewelry since 1974 and specializing in opal inlay jewelry for over 35 years.  His experience and knowledge make all the difference when working with opal to maximize the "fire" through skilled cutting and proper orientation.  Because no two pieces of opal are exactly alike, every piece of opal jewelry we create could be considered a one-of-a-kind work of art.  With top-quality Australian opal becoming more and more rare, our opal inlay jewelry is sure to become an important heirloom to be passed down for generations.  We produce a limited amount of opal jewelry every year with our focus being on quality over quantity.  Every piece of jewelry we create is made by hand in our Phoenix, Arizona jewelry studio by Mark and his son John.  We offer a full line of Australian opal jewelry including opal rings for women and men, opal wedding and engagement rings, bracelets, earrings, pendants and necklaces.  We can create matching multi-piece sets if you would like a matching opal jewelry ensemble.  Our opal inlay rings are all made to order in your specific ring size so please allow us 4 to 6 weeks to create your new ring.  All of our opal jewelry is available in white or yellow gold and can also be special ordered in platinum for an additional charge.  Keep in mind if you do not see the exact design you are looking for we can work with you to create a custom opal ring or any other type of custom jewelry you might want or need.

Opal is the October birthstone and symbolizes faithfulness and confidence.  Opal is the only gemstone known to man to have the natural ability to diffract light. As light enters an opal the light is split by millions of tiny silica spheres and voids. The arrangement and size of the spheres determines what colors the opal will fire or flash.  Opal is often referred to as the "Queen of Gems" because unlike other gemstones, an outstanding opal can flash all the colors of the rainbow. An opal's play of color is fascinating to watch as the colors dance and shift while rotating the stone. This play of color is opal's signature characteristic and helps to make every piece of opal jewelry a unique work of art.  Read more about how opal is formed, different types of opal and where opal is found and mined on our Opal Information page.
