Identify the real quality issues before you order

Start by defining your quality standards for sparkle, symmetry, and color stability so you know what “good” means for your end customers.

If you need uniform brilliance for a collection, you must verify that stones match in size tolerance and visual characteristics. Ask for details about grading and consistency practices, and request examples that reflect the exact stock you plan to buy. This reduces the risk of receiving stones that appear different from lot to lot, which can disrupt design timelines and production schedules.
