The fourth reason is design flexibility. Because lab-grown production is controllable, specific shapes, sizes, and qualities can be found or commissioned on predictable timelines. This matters for custom jewellery in concrete ways. If a design calls for a matched pair of 0.5 carat pear-shaped side stones, finding them through traditional supply channels can take weeks of searching across multiple wholesalers. In lab-grown, they can often be found quickly or produced to specification.
This flexibility enables design ambition. Three-stone rings with precisely matched sides. Toi-et-moi designs with complementary shapes. Larger centre stones in unusual proportions. Coloured lab-grown diamonds in fancy yellows, blues, pinks, and greens that are extremely rare and prohibitively expensive in traditional supply channels. For clients with a specific design vision, the lab-grown category opens options that traditional sourcing would severely constrain.
At Tailor Diamonds, our sourcing depth amplifies this flexibility. Because we work directly with leading growers and see broader inventory than most retailers, we can often present options that smaller specialists cannot match. Our thirty plus years of industry experience also means we know which growers produce which characteristics most reliably, letting us steer clients toward stones that will perform well both on paper and in the hand.
