I Had the privilege of working with Heidi to design a truly special pair of diamond studs. The quality of the stones combined with an embellished border was the perfect combo. The piece de resistance! Heidi`s idea to add a gorgeous aquamarine drop for black cocktail dress evenings. Integrity and creativity...Thank you, Heidi!

Ms Ortman Sheff has a discerning eye and has been a joy to work with throughoutt the years. She made a spectacular diamond wedding band for me, upgraded the look of my engagement ring by redesigning the setting, and has made an exquisite custom necklace for me. She is very well versed in market trends and value. I trust her implicitly to provide the highest quality at the best value.
