"Florence" engagement ring, lab grown diamonds, modern ethical jewellery, STEPHANIE VAN ZWAM, Swiss made

The Florence ring has a gorgeous trillion cut sapphire. A modern design inspired by Brunelleschi’s ingenious octagonal dome of Florence Cathedral. The particular shape of these eight segments is what has allowed the dome to stand without support since the 15th century. We cannot imagine a better way to celebrate your enduring love for one another than to reproduce this special shape for your engagement ring. The Florence ring breathes elegance, harmony, strength and timelessness.


Available in:
18ct white, yellow or rose gold.
