Questions & answers
Everything you might want to know before you visit or buy. If your question is not here, call us and we will help.
Help
How can we help?
Call +44 20 7430 9691 or email hello@platformjewellers.com.
Showroom open Monday to Saturday, 10am to 4:30pm.
Appointments
Do I need an appointment?
No, but we recommend it. Booking means a jeweller is set aside for you, with the right stones and settings ready when you arrive.
How long does an appointment take?
Around 45 minutes in the showroom. There is no obligation to buy.
Can I speak to someone before I visit?
Of course. Call us on +44 20 7430 9691 and one of our jewellers will talk it through with you.
Do you offer virtual appointments?
We do not offer video appointments, as we believe fine jewellery is best seen in person. We are always happy to talk on the phone first.
Can I bring my partner, or come alone?
Either. Many clients come alone to keep it a surprise, others come as a couple. We will make it comfortable either way.
Bespoke
How long does a bespoke piece take?
Typically 4 to 6 weeks from first design to finished piece. If you have a date in mind, tell us and we will be honest about what is possible.
Can I remodel a piece I already own?
Yes. We can reuse the stones, the metal, or both. More about bespoke.
Buying online
How long will my order take?
Most pieces are made to order in Hatton Garden. The estimated delivery date is shown on each product page before you buy.
How is my order delivered?
UK delivery is free, fully insured and signed for. You are also welcome to collect from the showroom.
Can I see a piece in person before buying online?
Yes. Book a private viewing from any product page and we will have it ready for you to try on.
Sizing
What if I do not know the ring size?
Very common and not a problem. Choose your best guess and we can size the finished ring afterwards. Our ring size guide has tips for finding it discreetly.
Can every ring be resized?
Most can. A few designs, such as full eternity rings, cannot. We will always tell you before you order.
Warranty & returns
What warranty do you offer?
Every piece is guaranteed against manufacturing faults. Read our promise for the full details.
Can I return or exchange a piece?
You can exchange within 30 days if the piece is unworn and in its original condition. Online orders can also be cancelled within 14 days of delivery. Full details.
Diamonds
Are your diamonds certified?
Yes. All our diamonds are ethically sourced and certified, and we will talk you through the certificate of any stone.
Do you sell lab-grown diamonds?
Yes, alongside natural diamonds. Our lab-grown vs natural guide explains the difference.
