Founded 1974 by Spencer Morgan, after a Royal Navy commission as a Lieutenant. Today run with his son Dorian, who trained at the Royal School of Jewellery in Birmingham and apprenticed in the Jewellery Quarter. Spencer's wife Julia and Dorian's wife Katy are on the shop floor. Two generations, two couples, fifty-two years, one Oxford Street address.
Round, princess, baguette, pear, cushion and oval cuts, set in platinum, 18 ct or 9 ct gold. Diamonds hand-selected and graded on the four Cs at the bench. Complimentary private consultation by appointment, with a side-by-side comparison of cuts and settings on the customer's hand.
Plain and stone-set bands in 9 ct, 18 ct gold and platinum. Profiles in stock: flat court, court, D-shape, bevel edge, deep shape. Eternities set with brilliants, baguettes or alternating cuts. Engraved on site. Sizing-down usually same day; sizing-up four to six weeks where additional metal is added.
Pieces created to the customer's drawing or to a redesign of an existing heirloom. Precious stones supplied and set: sapphires, emeralds, rubies, amethysts. The on-site bench means a redesign keeps every stone the customer brings in. No piece is sent away.
Chain and bracelet repairs, loose-stone securing, rhodium plating (usually within an hour), stone replacement and resetting, claw re-tipping, new shanks, ring resizing. All work on the premises. Your piece never leaves the shop.
The original idea is small. One shop on the main retail street, work done at the bench at the back, every ring sold from the same room it was made in. Five decades later, the shop, the bench and the room are still in the same place.
Today the workshop is run with Spencer's son Dorian, who studied at the Royal School of Jewellery in Birmingham and served his apprenticeship in the Jewellery Quarter. Spencer's wife Julia and Dorian's wife Katy are both on the shop floor most days. Two generations, two couples, fifty-two years, one Oxford Street address.
“They put me at ease straight away and my wedding band was resized by Spencer at the time in less than an hour.” Suzanne W. · Google review · January 2025
Most Oxford Street and South Wales jewellers send repairs away to a trade workshop in Birmingham or Sheffield. That means your grandmother's ring is in a courier's bag for ten days. Spencer Morgan runs the bench inside 247 Oxford Street, so a resize-down can be done at your coffee break and a rhodium re-plate on a white-gold band is usually inside an hour.
Metal removed or added by hand at the bench. Never stretched. The original profile is restored and the band refinished, so the alteration is virtually invisible and the shank keeps its full strength.
The original setting is examined, the matching stone sourced, the claws retipped and the setting rebuilt before final polishing. We do not cast-and-swap.
White-gold rings need re-plating every one to three years to keep their cool platinum-like finish. We do it on the premises, usually within an hour, no appointment required.
Bring a sketch, or bring an heirloom. Dorian or Spencer will talk through stone choice, setting style and metal weight with you across the counter, and the workshop will do the rest in the room behind. The bench is on Oxford Street, so the stones you bring in stay with us; nothing is sent away. Indicative turnaround on a from-scratch bespoke ring is four to six weeks once we have the design signed off.
A short form to book a complimentary private viewing on Oxford Street. We'll have the cuts and settings you mention pulled from the safe and laid out on a tray ready, so the appointment is spent talking through the choice in front of the stones, not waiting on them.
We'll confirm by email or phone, usually within the working day. Or call the shop direct on 01792 654 800.

Closed Sunday and Monday. Those are the days the bench gets the quiet hours it needs for the work that cannot be done with a counter open.
On site, at the bench inside 247 Oxford Street. Your piece never leaves the shop. That is the difference between us and almost every other South Wales high-street jeweller, who send repair work to a trade workshop in Birmingham or Sheffield.
Some are the same hour. Cleaning a ring is usually under an hour. Sizing down can be same day. Sizing up takes four to six weeks because additional metal needs to be added and finished. We call you when it's ready, never the other way round.
Yes, on the premises, usually within an hour. White-gold rings need re-plating every one to three years to keep that cool platinum-like finish. No appointment needed for the plating itself, but call ahead on a Saturday so we can have the bench ready.
Yes. Bring the piece in. We will talk through what stones you want to keep, what new setting style suits them, and what metal weight makes sense. The whole job is done on the bench in the back, so every stone you bring in stays with us. Indicative turnaround four to six weeks from sign-off.
By mid-October. The bench gets busy from November onwards and the sizing-up jobs need four to six weeks. If you bring it in by mid-October we can almost always have it back to you in time for the wrapping.
