Lab-grown stones above 5 ct are now realistic special orders, not novelties

Growers can now reliably produce lab-grown stones above 5 ct to order, a size that was a rare novelty a few years ago and is now a realistic, if still costly, special order.

• This builds on the growing availability of lab-grown stones above 3 ct we flagged previously, with the realistic ceiling continuing to move up.
• Growth time increases with target size, so a large stone still means a longer lead time than an off-the-shelf smaller one, even though it's no longer a sourcing gamble.
• Cut quality at this size has also improved, since cutters now have enough large rough to practise on rather than treating every big stone as irreplaceable.

A large lab-grown stone is worth planning for rather than expecting off a shelf. Contact us to discuss timeline and cost for a specific large-stone specification.
