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, the October birthstone, symbolizes faithfulness and confidence. Unique among gemstones, especially in opal rings and opal inlay rings—top quality Australian opal is famous for its dazzling play of color. As light hits the gem, it diffracts through millions of silica spheres, creating vibrant flashes and fire. Opal is known as the “Queen of Gems” for its unique ability to display full-spectrum hues that dance and shift with every movement as demonstrated in Australian opal rings and jewelry.

Each piece of opal inlay jewelry is a one-of-a-kind work of art, showcasing the gem’s signature play of color. To explore how these stunning stones are formed, the different types of opal, and the key mining regions in Australia—such as Mintabie and Coober Pedy—visit our full Opal Information page.
