A 12-month stock plan connects your sales history to your buying decisions. For lab-grown diamond retailers, it serves a specific function: reducing over-ordering during quiet periods while ensuring adequate inventory depth when demand peaks.

Lab-grown diamond stock requires active management. Without a structured rotation cycle, retailers accumulate slow-moving shapes, over-represent certain carat ranges, and miss reorder windows on the shapes that drive consistent sales. A 90-day operating model gives your inventory a defined rhythm- built around what moves, what stalls, and when to act.

Stock that has not moved within approximately 90 days is unlikely to sell at full margin without a pricing or display change. Beyond that window,...

What Is Carrying Cost in Diamond Retail Carrying cost is the total ongoing expense of holding inventory over a period. In lab-grown diamond retail, it has four components: Capital cost: the opportunity cost of money...
