I've had jewellery custom made from this store - they were great, had time to sit down and talk through their metals and gemstones etc. were willing to work with my design and have designers of their own with feedback to contribute.
I have also had jewellery resized here. Ranging from a bracelet (with several cord strands and sterling silver, they were able to add more links to the clasp and you would never know the difference) to a diamond ring (gold, with diamonds running along the band, they were able to make it significantly bigger - as I received it as a child it was very small, and still keep the diamonds intact, the shape is a little odd when you look at the ring on a table - due to the line nature of the diamond setting, however when you put it on, you don't notice at all!)
Great service, reasonable prices, great quality, fast turnaround!
