Setting The Benchmark In Color Calibration

Our Gemstones

Our Zambian emeralds are celebrated for their rich, saturated green color and clarity. Each stone is ethically sourced and hand-selected for its inherent beauty, then precisely calibrated in our state-of-the-art facility. With uniformity in shape, size, and brilliance, our emeralds are ideal for fine jewelry, bridal collections, and matched layouts.

We offer Mozambique rubies known for their tone, vibrant saturation, and radiant luster. Sourced from ethically responsible mines, each ruby undergoes careful selection and expert cutting to ensure precise symmetry and dimensional accuracy. Our calibrated rubies guarantee repeatability, strength in color, and refinement in make, suitable for both high jewelry and commercial excellence.

Our blue sapphires, sourced from Ceylon, exhibit the finest velvety hues, ranging from royal blue to midnight tones. Each stone is cut to exact proportions and polished to perfection, delivering exceptional brilliance and unmatched color consistency. With premium calibration across shapes and sizes, our sapphires are widely used in watches, bespoke jewelry, and brand collections that demand both beauty and batch consistency.
