What You Can Customise

• Gold purity and colour: 14K or 18K, in yellow, white or rose.
• Necklace length to suit your neckline.
• Matching earrings to complete the set.
• Diamond shapes and sizes on many designs.

Planning a Wedding Necklace

Order at least four weeks before the wedding to leave time for any changes. Send us your outfit colours and neckline on WhatsApp, and we will suggest designs that suit them. Made-to-order pieces cannot be returned or exchanged, so ask us anything before you order.

Why Lab Grown Diamonds Are the Smarter Choice

Lab grown diamonds are real diamonds. They have the same carbon crystal structure, the same hardness of 10 on the Mohs scale and the same fire and brilliance as mined diamonds. They cost almost 90% less than natural diamonds of the same grade, so your budget buys a bigger, finer stone. For a clean, bright look we recommend VVS1 or VVS2 clarity.
