    So happy with our rings!

    Greg made the whole process of viewing/designing rings a very relaxed event with no feelings of pressure or uneasiness. He is super friendly, kind and knowledgeable about gems and jewelry. He discussed differences of mined diamonds vs. lab gown diamonds and helped us make an informed decision. He created my engagement ring and our wedding bands exactly how we wanted them! He also helped us convert a family heirloom pendant into a beautiful ring. We are completely satisfied and immensely happy with each piece of jewelry he has crafted for us. Thank you, Greg!
