WHAT YOU SAY ABOUT US
Reviews from our clients
Rebecca Schott
Nissan, David and his team were extremely accommodating, understanding and patient with our purchase. They took the upmost care to find the best solution for our needs and went above and beyond normal 'customer service' standards. I have absolutely no qualms recommending their products and services. Both were absolutely flawless. I will continue to sing them praises and will most definitely purchase from them again in the future. Thank you again!

After checking their website I sent an inquiry. The following day Nissan contacted me to help me further pinpoint what I was looking for. Both Nissan and Grace are very helpful and thoughtful of helping you getting the right diamond. Grace took the time to explain me the differences which was very helpful. Will recommend this place to friends and family.
James Prince
An amazing experience from the moment I arrived for my first meeting with Nissan. I was a complete innocent about diamonds and jewellery, and Nissan put me at ease, and gave me the confidence to make a perfect choice. I honestly could not recommend him more. And I now have a VERY happy fiancée!
Gershom Menachem
Great team of diamond experts who show personal care for the client’s needs and aftersales service. They really go the extra mile to make it happen no matter the challenges ahead. Rush orders, international shipping, upgrade service, jewelry repair, large diamonds, small items, precious stones. Very honest and open information to the clients. You will feel like talking to a friend.

We had Grace to help us with the engagement ring, the marriage band for both of us and some earrings. She was extremely helpful through the entire process, and even with the earrings I got them exactly how I wanted them. Can recommend anyone who is looking to buy diamonds to buy from Diamond registry. Good service, beautiful stones, quick respond rate.

We were referred by a close friend and we were extremely thrilled with their excellent service! Both Grace and Nissan were patient , polite and professional and found us a top quality diamond. The ring was exactly what we wanted and the price was very reasonable complete with certification . I would highly recommend them and we will be going back ! Thank you Grace and Nissan.

Bought a beautiful stone here for an engagement ring. I was a little apprehensive since you're buying something unseen. But Cid made it easy. In fact, Nissan, the owner also gave a call to make me more comfortable. They sent me the stone to take to a local jeweler with only my Amex in case I bailed on them.
David L.
I am absolutely thrilled with my experience at Diamond Registry. I have purchased many expensive pieces of jewelry, including large diamonds, for my ex-wife over the past 20 years. My recent purchase from Nissan and Shai Perla was by far the most pleasant, courteous, transparent and efficient. Never was I pressured or "sold."
Valerius Reza
Very recommended! Grace from Diamond Registry is very helpful and patient to help me finding the perfect engagement ring for my fiancé. The diamond is also affordable with very good quality. Thank you, Grace!
