I heard about Twinkle Diamonds through one of the people that work there, Devansh (Dave). To provide background, I was in need of a pair of wedding rings and Dave made the process as smooth and uncomplicated as possible. I am going to speak with Twinkle Diamonds again around my soon-to-be wife's birthday to get her another ring as a gift.

I have recently dealt with Sunjay regarding an online purchase from SA. His communication, service and delivery on what he said the product was has been exceptional. I am extremely happy with my new 80cm pearls.
— Jayne McLaren
Went to Sunjay to design an engagement ring he was really helpful from beginning to end. The quality and look and the ring is stunning.
— Joachim Jenni
Sunjay was incredibly helpful when I came into custom design my wife’s engagement ring and offered an amazing price for the high-quality ring he created. Naturally, we came back to organise our wedding bands and of course he was equally amazing as the first time. I would highly recommend Twinkle Diamonds if you want top quality, professional service and excellent value.

My fiancé and I came all the way from Melbourne to pick up my engagement ring because we couldn't find a trustworthy diamond dealer who could provide us with a clean diamond. Thankfully Sunjay in Sydney was able to provide us with a flawless diamond and he was able to design my dream ring. I couldn't be happier and I can't stop looking at my beautiful ring. If you are looking for a diamond ring I can assure you that twinkle diamonds will not only provide you with the best diamond but he will give you the best price.
We thank you dearly Sunjay and we will see you in the near future to design my wedding band.

Never have I had a better experience than dealing with Sunjay. The flawless finish of the diamond ring and quality of the cut surpasses all comparable vendors. It is without a doubt that if you want a piece of jewellery that makes a statement and lasts an eternity there is only one place. Will be going back for all future items of jewellery.

Excellent service and prices. Sunjay was amazing to work with. He teaches you everything you need to know about the diamonds, the ring, and the crafting process. He is clear about pricing upfront and delivers a premium finish. Bought both the engagement ring and wedding ring from him.

I have to thank Sam for putting up with me while helping me pick out just the right diamond for an engagement ring. He provides excellent service and he made sure I knew everything I needed to know before I went ahead with the purchase. Many thanks.
