What Our Clients Are Saying

My husband and I chose NCD to assist us in finding the perfect engagement ring that would compliment my style. We mostly dealt with Stephen who was very knowledgeable and really took the time to listen to what I was looking for and offered a really great selection of options to choose from. Thank you Stephen and NCD; I couldn't be any happier with my brand new canary yellow diamond ring. You wouldn't believe the compliments and interest that people give it. I just love it!! Thank you again for everything!

Working with Northern Cross Diamonds was great!  The staff was very knowledgeable and provided me with a great deal of information about the canary yellow radiant cut diamond that I purchased.  They wanted to make sure that I understood everything about the stone before I made my decision.  The price was very competitive, less than other diamond providers.  Once I had made my decision to purchase, the process and delivery time was very quick.  Now I have a beautiful and valuable diamond in my possession, thanks to Northern Cross.  I hope this helps spread word about your services.

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.
