“…exactly what we were wanting.”

“I had a set of custom-made earrings for my partners birthday. Ron was extremely easy to deal with and managed to get us exactly what we were wanting. I would highly recommend Adamastar to anyone. Great service, great quality and reasonable prices.”

“…made it very easy to bring my dream engagement ring to life.”

“Ron & team are awesome to work with. He made it very easy to bring my dream engagement ring to life. I haven’t seen the ring yet (we’re keeping it hidden until a specific time) but from what I’ve heard, it’s stunning!”

Sarah C

“… the communication from Ron and the team was really great…”

“The ring is beautiful! It took a tad longer to receive than expected, but the communication from Ron and the team was really great, keeping me in the loop at every stage of the process. The ring was also a tad big, but they put it right and paid for the resizing since we don’t live in Auckland, and they couldn’t do it themselves. My fiancé is really happy with the ring, and it looks amazing.”

Nick S

“I love my beautiful diamond ring!”

“A chance venture on the web led us to Adamastar and using the website made the choice of the ring a stress-free experience. As well, the gemmologists were extremely generous in sharing their time and knowledge with us. Overall, a very enjoyable and satisfying experience…”

Anne, Auckland

“Can’t recommend Adamastar enough.”

“Enjoyed dealing with the guys at Adamastar. Their site is easy to use, and we were able to make a few changes to the ring we liked so we managed to get exactly what was our dream engagement ring….”

Petra, Manukau

“The compliments keep coming!”

“We never considered a lab grown diamond before we saw them on Adamastar.co.nz and were surprised how beautiful they look and how reasonably priced they are. We were able to buy a bigger diamond than we thought we could…”

Colleen, Auckland

“Adamastar were absolutely fantastic to deal with! “

Excellent service and friendly staff! Thank you for a great experience!

“The Adamastar site made it so easy for us…”

“I bought a Lab Grown Diamond for my fiancée knowing nothing about diamonds and jewellery, but the Adamastar site made it so easy for us to make up our minds and the green ethical side of these diamonds really appealed to both of us as well as the fantastic price. My fiancée is wrapt in the diamond. Thoroughly recommend these guys who answered all our questions, and we were able to see the diamond before we purchased the ring….”

Jonathan and Karen, Northcote

“Very happy with the whole experience”

“These guys know their stuff about lab diamonds and talked us through the whole exercise, and we ended up with a beautiful diamond ring. I love it. Definitely recommended….”

Nicky, Whangarei

magnicent gemstone

If you were fortunate enough to discover a rough diamond in the ground, you might assume it is just another unremarkable, irregular shaped pebble.

It has taken diamond cutters generations of experimenting and passing down the (often jealously guarded) knowledge, of the physical and optical characteristics of such an unremarkable pebble, to bring out the brilliance and fire of a polished round brilliant cut diamond.

There is a wonderful symmetry with artisans skilfully beautifying this magnificent gemstone and now, with human ingenuity, actually creating it.

A lab-grown diamond is a diamond for the future. We invite you to experience the wonder of lab-grown diamonds for yourself in an exquisite piece of jewellery from Adamastar.
