We invite you to an exclusive five day private showing of an exquisite array of jewelry from Featherstone along with a deep collection of colored and fancy gemstones from Gem Dealer and Australian native, Mark Tremonti who has supplied the world’s most prestigious jewelry houses for over thirty years. We hope you can join us for this unique opportunity to purchase rare gems from the source.

For five days this June, Deirdre and Mark will accept clients together. Mark is flying in with his stones from Australia to co-host this private event at the Waldorf Astoria Towers, where the Featherstone Collection will be on display for private appointments. This is a unique opportunity to work with some of the world’s most spectacular stones and envision a one-of-a-kind piece of custom jewelry.

Mark Tremonti has created the most direct link possible between the miners who find and process stones and their final destination. By being associated with both the mines themselves, as well as processing and distribution, Mark is able to ensure the utmost clarity and quality in every gemstone he offers. Mark’s mining career began in an Australian sapphire mine in 1985. He soon expanded to colored diamonds and opals, which eventually led to his work in mines all over the world. Mark has sourced stones for countless award-winning designs and prestigious jewelry houses. He is one of the most eminent sources of Australia’s coveted Black Opal and Argyle Diamonds – two of the most valuable stones in the world – as well as sapphires and other colored diamonds.

In September 2014, Deirdre went on a ten-day private tour through the Australian Outback. She visited five different mining regions to meet the miners and families that have provided gemstones for Featherstone Design’s award-winning creations. The tour was arranged by the National Opal Miners Association (NOMA) and the Gemological Association of Australia (GAA).
As a central point for the Featherstone collection, Australian opals provide a spectrum of color that not only complements the other fine gemstones in the collection, but also intensifies the overall impact of each piece.
