What Our Clients Are Saying

I have used Northern Cross Diamonds for the last couple years. I have a full time job, rental properties, stocks and mutual funds, yet I am always looking for new investment opportunities. Meeting and dealing with the professionals on staff (especially Stephen) has pointed out creative ways of maximizing the investment potential within coloured diamonds. They are always there to answer questions when I am curious on making a new investment and the experience has been nothing but great!

I found Northern Cross Diamonds because I was looking for a colored diamond for an engagement ring to propose with. There are not many companies that have colored diamonds but they have quite a few. After considering for a couple of weeks, I decided to contact them to discuss the diamond I was looking at. The guy I worked with, Stephen, was very kind and helped me with the purchase process. I even had to ask them to ship my stone across the world to China.  After I received it I had no doubt about the high quality of their products. I appreciate Stephen and Northern Cross to help me to achieve my perfect proposal plan. I am very happy to have done buisness with them and I will definately recommend Northern Cross Diamonds to anyone looking to get married or who would like to add more stones for their collection. Again, thank you Stephen

I have bought several coloured diamonds from Northern Cross Diamonds.  I have found that Northern Cross gets me the best prices -- even when the diamonds come from another vendor and are listed with the other vendors at a higher price.  Stephen Mitanidis has spent hours of his time educating me on coloured diamonds and helping me to choose diamonds that have the best investment potential.  He has also allowed me to trade coloured diamonds that I own for coloured diamonds that I want and has assured me that Northern Cross will help me to sell my coloured diamonds if I choose to do so. If you buy a coloured diamond, I recommend that you consider showing it to your family members and friends. Most of them will be impressed with how it looks and might want to seize the opportunity to buy one or more before the value of coloured diamonds appreciates further.
