the classic engagement ring | solid gold
Tax included. Shipping calculated at checkout
The flat, shiny ring, set with a sparkling diamond, is the classic among engagement rings. A lab-grown diamond with 0.13 carats and a high-quality brilliant cut is the centerpiece of this classic design. Who could say no to that?
We have pre-produced our standard sizes in yellow gold; these can be ordered immediately. Our regular return conditions apply to these rings.
If you need a different size, select the "Custom Size" option and enter the correct ring size in the 'Custom Size' field.
The production time for your custom size is 4-6 weeks.
Helpful tips for determining the correct ring size can be found in our blog on measuring ring size, and a suitable ring size chart for download.
We will send you the ring in a high-quality and environmentally friendly case.
Size adjustments - the ring should rather be bought a bit too large than too small; later, it can be secured with a stacking ring or the wedding ring, for example. Subsequent, paid size adjustments should be avoided if possible due to the set diamonds: the engagement ring can only be enlarged/reduced by a maximum of one size, e.g., from 52 to 53 (16.5mm inner diameter to 16.9mm) and vice versa.
Returns - Should you need to return your custom-made engagement ring, we will unfortunately only be able to refund 50% of your paid sales value. In the event of a wrong delivery on our part, we will, of course, refund 100% of the purchase price. We thank you for your understanding!

Don't know your ring size? Here we have a few tips on how you can easily determine your size.
Upon request, we can also increase or decrease your favorite ring by 1-2 sizes.
Your piece of jewelry is made of solid 14K gold and is designed to last a lifetime. Since it is not gold-plated, the gold layer cannot wear off.
Even real gold can develop fine scratches and signs of wear over time from daily wear. Cosmetics, perfume, chlorine, or other external factors can also affect the surface. We therefore recommend handling it with care and cleaning it regularly and gently, for example, with a soft cloth or a mild cleaning solution.
Is your piece of jewelry defective, or did something break while you were wearing it? Feel free to contact us. We’ll check whether it’s covered under warranty or what options our repair service offers.
