    Had a fantastic experience with staff at Moi Moi! Puchased an amazing lab-grown diamond ring here and the quality of the ring as well as the customer service was excellent. The staff were very patient and informative. The price was of course much more reasonable than any of the other diamond jewelers we went to. Would definitely recommend to friends and family.

    I bought a ring last year my husband picked the style (online, so didn’t try it on). After crafting the ring and wore it for a while I found it a bit uncomfortable (for my personal liking). So I contacted Oz who was very very efficient on replying and helpful and he suggested to me that instead of changing the style I could craft another ring with my existing stone, it ended up saving me thousands of dollars. Now after Less than 4 weeks I’ve received my new ring and it sits perfectly with my wedding ring. Only if the review would like me share a photo of it. I love it so so so much. I already recommended Moi Moi Fine Jewellery to my friend who also bought her ring and eternity band I will continue spreading the good words and let all my lady friends know how awesome and helpful the staffs are and how stunning their rings are, also affordable!

  • Thank you for coming to the rescue Moi Moi! My wife damaged her engagement ring during a fall. The claws had retracted from the stone. The ring was entrusted to Moi Moi for repair and rhodium plating. We took the opportunity for her wedding band to be rhodium plated too. The job was turned around in 2 business days. The rings look like new (even though they are actually 12 years old). Shiny, sparkling, beautiful. Thank you Moi Moi.

    This is the second time that I have purchased from Moi Moi Fine Jewellery and on both occasions it has been an absolute pleasure. The rings that I have ordered and purchased are stunning and beautifully crafted, Moi Moi definitely know what they are doing and they produce pieces that are exquisite and are finished to the highest standard. What keeps me coming back besides their beautiful pieces is their exceptional customer service, every person I have dealt with has been fantastic, personable and honestly a pleasure to deal with, always so kind and friendly and more than willing to go the extra mile for me and make me feel valued as a customer. These days customer care and service like this is very hard to find. I honestly highly recommend Moi Moi Fine Jewellery and I will definitely be purchasing from them again, they have a customer for life here!!

Moissanite is the most brilliant jewel in the world. It has more brilliance, fire and lustre than a diamond. Moissanite is ideal for an engagement ring due to its better quality, better value and being better for the environment than a mined diamond.

Quality and value. Moissanite has better optical properties than a mined diamond and yet it is at a fraction of the price of diamond.  Its seductive beauty and exceptional value make Moissanite ideal for engagement ring.

Lab grown diamonds are identical to mined diamonds in terms of appearance, chemical and optical properties. They display the same fire, scintillation, and brilliance. Premium lab-grown diamonds are graded the same as mined diamonds using the same value factors – the 4 C’s.

You choose lab grown diamond because you are attracted by the environmental and social responsibility reasons of the lab grown diamond. Furthermore, the value is undeniable. You get a bigger look at the same budget or simply save big for the same diamond quality and size.
