Phillip made the process of purchasing my jewellery straightforward and pleasant. From the initial email correspondence to being welcomed in the office, I appreciated the professional approach, clarity and obvious knowledge of the trade.
I strongly believe that Phillip offers the fairest prices, and the payment was instant.
Both Phillip and Danielle are very courteous and I would definitely choose them for any future transactions. Thank you!

My reason for contacting Celsteel Diamonds is because I wanted to sell a diamond. I visited a few places close to where I live but the expertise and knowledge was missing.

The entire process was easy and I’m glad I kept searching and found them. Would highly recommend as got a fair and good price for my diamond,

I met with Phillip to get a valuation of my engagement ring. He was courteous, honest and put me at ease. I was a little nervous about the process as I hadn’t sold a ring before. He made the whole process a pleasure and I left with an amount that I was happy with. Phillip was easy to talk with and I felt relaxed and would highly recommend him to my friends and family if they want to buy or sell diamonds. , He had a professional and warm presence and was knowledgeable and transparent throughout the whole process.

I called in to see Phillip hoping to get a good price for an unwanted ring.

Over the years I have dealt with a lot of jewelers in different countries but to be honest none have been as helpful and as straightforward as Phillip was when we met.
He thoroughly cleaned the stone before valuing it. Within 20 minutes we had agreed a price and the money was transferred in to my bank account before I left his office.

If you are looking to buy a stone then a visit to Celsteel Diamond is a must. Apart from being looked after really well you will be in a very safe environment in their office.

I have friends in many countries and everyone will be told where to go if they want to buy a stone.

I emailed my signed declaration form Friday morning (around 7.30am) Phillip responded immediately (probably over his breakfast, in his own time) to let me know that when he got in to the office he would transfer monies. Money was in my account that morning. A very friendly and superb service received and a very happy customer 😊

We had a friendly greeting followed by having all details explained in selling a diamond. Each step was shown about our diamond clarity,weight etc. After all put together a price was offered, we were given time to decide or go away and think about it even go somewhere else to see if we could get a better price. The offer was close to what we already knew, agreed sale payment received. Left feeling relaxed over whole experience.
