Frequently Asked Questions

What materials are used in your engagement rings?

All our engagement rings are crafted from the finest materials including 18k white gold, 18k yellow gold, 18k rose gold, and platinum. We source ethically and responsibly, ensuring each piece meets our exacting standards for purity and quality. Every ring is hallmarked and comes with a certificate of authenticity.

How do I determine my ring size?

We recommend visiting a local jeweller to have your finger professionally measured. Alternatively, you can use our free ring sizer kit, which we'll post to you. For the most accurate fit, we suggest measuring your ring size in the afternoon when your finger is at its warmest. If you're between sizes, we recommend sizing up slightly for comfort.

What is your delivery timeframe?

Standard delivery for our ready-made collection is 5-7 business days within the UK. For bespoke commissions, the timeframe is typically 8-12 weeks, depending on the complexity of the design and current order volume. We offer expedited shipping options for an additional fee. All rings are insured and delivered via secure courier.

Do you offer bespoke commission services?

Yes, we specialise in bespoke engagement ring commissions. Our master craftsmen will work with you to create a truly unique piece that reflects your vision and personal style. The process begins with a consultation to discuss your ideas, budget, and timeline. We'll create detailed sketches and 3D renderings before crafting your ring.
