Meet The Opal Man - Dennis Dahl

Dennis Dahl

Opals. Of all God's creations, opals are the most amazing stones he has created. Opals come in a wide variety, in colors, in patterns, in types of background color and in the intensity of the color, it is a kaleidoscope of pure joy. People love diamonds because they sparkle, but opals you can fall in love with because they appeal to the heart.

The Opal Man carries a great variety of opal; Black, Boulder, Koroit Boulder Opal, Crystal, White, Honey Matrix, Treated Matrix, Opal Doublets, Opal Triplets, all for your viewing pleasure. Colors, patterns, and flashes of anything you can imagine.

I am a professional opal cutter with over 50 years of experience in cutting all types of opals from the rough that I buy on the opal fields.  I cut opals to maximize their innate beauty and display their exciting array of colors.

I enjoy all the many varieties of opal that are produced in Australia and many other countries throughout the world. Most of the opals I carry are from Australia which produces about 90% of the world's opal supply.

Few other places produce opal that has the depth of Black Opal, the crisp colors of Crystal Opal, or the flashy brilliance of Boulder Opal.

We have a huge range of cut and polished opals. If you are looking for something specific please send an email. Additionally, I am always cutting new opals. If you are in the trade, please let me know.

~ Dennis Dahl, The Opal Man


I have been in the wholesale opal business since 1970 and started cutting opals in 1972. The business started in Rockford, Illinois under the name of Harlequin Enterprises, renamed in 1973 to Midwest Gem Cutters. In 1975 I moved to Hanover, Illinois, and in 2001 another move was made to Spring Green, Wisconsin as well as a name change which is now The Opal Man.

In 1976 I started buying rough in Australia with the intent of carrying as many varieties of opal as I could, since most people here in the United States thought opal was just white. Having spent 4 months working in an opal shop in Surfers Paradise, Queensland in 1969 I had seen a lot of beautiful opals of all types: Black, Crystal, Boulder, Koroit Boulder and Treated Matrix, as well as Opal Doublets and Opal Triplets.

Australia has become like a second home to me since the first time I went in 1969 for a three-month working vacation and ended up staying almost a year, which wasn't nearly enough.
The bulk of my business has been in the Midwest serving Illinois, Wisconsin, Iowa, and Minnesota but also Denver and Boulder, Colorado. Over the years, I have developed customers in a great many states.

The reason for this web site, is hopefully, to be of better assistance to my customers by displaying a portion of my stock on the web but certainly not all. If you have a specific request please send an email and let me know what you are looking for. If we don't have it in stock we have the ability to cut from the rough opal we have on hand.
