How stones are grouped for your project.

Pair
Two emeralds selected for close consistency in shape, size, color and clarity — for earrings or symmetrical settings.
Trio
Three harmonious emeralds selected together, for three-stone rings or coordinated pieces.
Production Lot
A larger quantity of emeralds sourced to a consistent specification, for collections or repeat production.
What are matched emeralds?
Matched emeralds are selected to look harmonious together, with the closest possible consistency in shape, size, color, clarity and overall appearance.
What are Requested Units?
Requested Units reflects how many of a given selection you need — for example, 3 requested units of a Pair means 3 pairs, or 6 emeralds in total. Carat Weight always refers to each individual emerald, not the combined total.
