We are situated in the heart of the Birmingham Jewellery Quarter, at 46/47 Warstone Lane – just by Chamberlains Central Column clock, right next door to Barclays Bank.

Yes, we are open 7 days a week (except Easter Sunday, Christmas Day, Boxing Day and New Years Day).


Diamonds sparkle because of the way light works within the stone. Light funnels into the top of the diamond, disperses in a circle and then funnels back out of the top of the stone again. Therefore, round diamonds give the most sparkle of any diamond shape.

There is no need to pre-book a consultation, as our showrooms are open 7 days a week and all our staff are experts in assessing the suitability of a particular design for each individual – so simply come along at your leisure and we will assist you.


We use the Royal Mail. All shipments will need to be signed for at delivery and all are trackable.

Please contact us for more information on international shipping.


Any purchase made from Marlow’s comes with a lifetime free cleaning and polishing service.

We can certainly arrange engraving for you, as we utilise a specialist engravers within the Birmingham Jewellery Quarter. Alternatively, you are free to visit them directly.

We have 3 manufacturing workshops, so depending on the complexity of the design, we can manufacture a customised engagement ring in as little as 2 hours.

All our products come packaged in presentation boxes.

Our product range is too vast to be covered in a catalogue, but we show a wide selection on our website. There is no equivalent for seeing a diamond in the flesh, though, so a trip to our showroom is a must.

We want the best for you, just like you do. All our diamond jewellery, including engagement rings, is made with the highest quality diamonds. It’s okay if you don’t believe us but you will have to believe the GIA which is the most trusted diamond grading organization in the world. All our diamonds are tested and graded by the GIA experts. We will provide you the proof in form of certificates issued by the same so you can check the details of the diamond engagement rings you have shortlisted. In fact, you can check these certificates online on our product pages before you even make the purchase!


The carat is the physical weight of the diamond and not the actual measurements of the stone. We hold a huge range of different carat weights in our showrooms, in a multitude of shapes. We have one of the largest stocks of diamonds available to view in the UK, ranging from 0.20cts – 10.00 cts.

All our certified diamonds are provided with their authentication certificate and a valuation certificate for insurance purposes.

We strongly recommend you consider the GIA, IGI and HRD laboratories. Our diamonds are renowned for superb quality and all come with independent certificates from internationally recognised bodies, such as GIA.

Despite being one of the hardest natural substances, diamonds can be cut. Expert diamond cutters will use the cleaving or sawing process to cut diamonds. To shape, facet, and polish a diamond, diamond-coated tools are used. 

Cleaving and sawing are the two main methods for cutting diamonds. Cleaving is used when the diamond has notable grains, allowing the diamond cutters to easily identify structural weaknesses to split the rough stone. Sawing, which uses lasers or diamond-coated saws, is more commonly used as it offers greater control and precision. 

Before cutting, a diamond looks like a translucent stone. It lacks the iconic shine and facets but has a unique raw beauty.

Before polishing, a diamond has its shape and facets but lacks the final shine. It will appear a bit cloudy, waiting for the final polish to glow brilliantly.
