Bianca Tavae I have purchased a beautiful diamond cross and necklace for my daughters Christening and a Gold Chain for my husbands Birthday from Gilian Jewellery, and I couldnt be happier with my experience. The craftsmanship of the cross is outstanding—elegant, detailed, and clearly made with care. The cross has a timeless design that feels both meaningful and stylish, and the chain is sturdy yet delicate enough to wear comfortably every day. Customer service from Mary was excellent from start to finish. Mary was knowledgeable, patient, and helped me choose the perfect pieces. I would definitely recommend Gilian Jewellery, to anyone looking for high-quality jewelry and a smooth, professional shopping experience. I’ll be coming back for future gifts and personal pieces.

Toni Galavin Excellent communication throughout each step of the design process!! Absolutely beautiful, custom creation on a quality wool hat!! LOVE it and will wear it for years to come!! You won’t be disappointed… excellent price for a quality, custom designed hat!!

Vanessa Toutounji Had a great experience with Cosimo. I had a ring that was missing a diamond and Cosimo was able to give me options with different budgets to suit my needs which was great. He also identified a crack in the ring which had led to the diamond falling out and fixed it. Would definitely recommend Cosimo for all your jewellery needs!
