For Birmingham couples shopping for an engagement ring, traditional jewellery stores are no longer the only option. Lab grown diamonds give buyers another way to find certified diamonds while exploring different styles, specifications, and price points.
For shoppers interested in ethical engagement rings, lab grown diamonds can also be an alternative to mined diamonds. But finding the right ring still requires comparing more than the advertised price. Certification, diamond quality, setting, return policies, shipping, and customization can all affect the final value.
We compared seven retailers offering lab grown diamond jewellery or engagement rings. Some are online specialists rather than Birmingham-based jewellers, but they provide options for UK shoppers who want to compare rings beyond the traditional high-street market.

Popular Styles: Oval and Vintage Cushion
The diamond shape can have as much influence on the final appearance as the setting.
Oval Lab Grown Diamonds
Oval diamonds combine an elongated outline with brilliant-style faceting and can work with solitaire, halo, hidden-halo, and three-stone settings.
When comparing an oval lab grown diamond, look beyond carat weight. Check:
- Length-to-width ratio
- Symmetry
- Colour
- Clarity
- Cut quality
- Bow-tie appearance
- Certification
The right combination can create a ring that feels modern while retaining a traditional engagement-ring appearance.
Vintage Cushion Styles
Cushion diamonds have a softer outline and work particularly well with vintage-inspired settings.
They can be paired with:
- Halo settings
- Pavé bands
- Hidden halos
- Yellow or rose gold
- Detailed shoulders
- Three-stone designs
For couples who want something romantic and distinctive, a cushion-cut lab grown diamond can provide a different look from an oval or round.
How Birmingham Buyers Can Avoid Paying the Markup
The best way to compare engagement-ring prices is to compare similar specifications.
1. Compare the 4Cs
Check carat, colour, clarity, and cut rather than comparing carat weight alone.
2. Check Certification
Look for an independent grading report and verify the diamond’s certificate details before purchasing.
3. Compare the Setting
Metal type, side stones, craftsmanship, and setting complexity can significantly change the final price.
4. Review the Return Policy
Check whether the return period begins from shipping or delivery and whether customized or engraved rings are excluded.
5. Check UK Delivery Costs
International buyers should confirm shipping, insurance, VAT, import duties, customs handling, and return-shipping requirements.
