Very good

The ring came out great, and despite pressure from me on time, they delivered it earlier than promised. Very pleased.

A very happy returning customer

I have been a returning customer to this company over the past few months. I have purchased some beautiful loose sapphires which have all been as stated and photographed. They have been really helpful when ordering diamonds too.
Postage is quick, free and tracked. When one stone didn’t quite fit in with the ring stack I am building, the returns process was easy.
They all seem like genuinely nice people to deal with via email too. I am looking forward to diamonds being back on the website as I have some plans for new jewellery and I don’t want to take my business anywhere else for loose stones.

I cannot thank you all enough. The quality of product from stone to setting is astounding. The stone is so bright its encapsulating. Very prompt responses to email and the design process quick, easy and above all - accurate! Exactly what i wanted and the finished result is nothing short of amazing.

Beautiful rings

I purchased two vintage rings from this store. These 20+ year old rings are in perfect condition, even more beautiful in person and they came in original boxes. Shipping to the US took less than a week! I’m very happy with my purchases and will be returning.
