5 /5 Sara Just: Mireya worked with my husband for almost two years, on and off, to design the most amazing emerald and diamond earrings and pendant set for my 50th birthday. The emeralds are exquisite and I am amazed at how beautiful the set is every time I wear it. Even though it took him quite a bit of time to make a final decision and purchase, she was attentive, responsive and extraordinarily helpful in teaching him about emeralds and providing design ideas. We would highly recommend them to anyone that wanted high quality gems and fabulous service.
