Welcome to GemMatrix

High-Quality Loose Stones
SINGLE GEMSTONES
For 17 years, we have been experts in our field, offering only the highest quality gemstones on the market. Whether the stones are mined in Madagascar, Tanzania, Sri Lanka, Colombia or any other part of the world, our experienced gemologist experts frequently pick them up directly from their source. They also ensure that each stone is of high quality and can be used in fine jewelry.
From rough to cut and polished calibrated gems
CALIBRATED GEMSTONES
Calibrated stones are a must for producers of jewelry to create pieces that are standardized in color and quality. Tolerances for size and hue are our main quality. We are consistent and efficient. We understand the market demands and store sufficiently rough/cut products to satisfy on-time demand.
