Ruby and Sapphire Calibrated Buying Notes

How calibrated ruby and sapphire parcels can support repeatable design programs when sizing, color, and availability are reviewed together.

Calibrated buying works best when dimensions, color impression, and production tolerance are considered as a group instead of as isolated product attributes.

For jewellery programs, the goal is often dependable replenishment and consistent presentation across multiple pieces, not only a single standout stone.
