A necklace moves with you, so we design ours to keep the diamond facing forward: short bails, balanced pendants and chains matched to the weight of the stone. Neckline Sonnet is the result, a set of pieces meant for daily wear rather than the safe.

Each necklace set is made to order in 18K gold, PT950 platinum or sterling silver with a lab-grown diamond from our own production. Production takes 10 working days; we ship worldwide by air with tracking.

FAQs about Lab-Grown Diamond Necklaces

Is a chain included?

Yes — each necklace is made as a complete piece with its chain, in the same metal as the setting.

Which stone weights are available?

From 0.3ct to 5ct on most designs. Five-stone and cluster necklaces state the total weight, for example 0.2ct×5 = 1ct.

Which necklace suits everyday wear?

A single-stone pendant in a bezel or low prong setting sits flattest under clothing. Necklace lengths and necklines covers how length changes where the stone sits.

Which metal suits a necklace worn every day?

The chain is made in the same metal as the setting. 18K yellow, rose or white gold, PT950 platinum or S925 sterling silver are all offered; silver is the one that tarnishes over time and needs the occasional polish, gold and platinum do not.

Will I pay import duty?

Import duty and tax are paid by the recipient. For a US delivery that currently adds roughly a quarter of the item value; the UK and EU are similar once VAT is counted, and Japan, Singapore and Taiwan are much lower. Full country list.
