Master stones in cubic zirconia

Master stones in cubic zirconia

The best imitation of the diamond. Each master stone is guaranteed never to fade, and every set is graded to perfection.

Use the Master Set Pro 2 diamond color-grading kit from GemOro® to professionally and efficiently color-grade diamonds. Treated with the exclusive GemOro ColorLast™ Technology, each full-carat stone offers accurate and permanent color saturation across a broad, 10-stone reference range; each color is expertly hand-graded to master diamond color standards using the GIA grading scale. The set helps you to match a diamond to the correct color master. The Pro 2 includes a unique, patent pending protective storage case that doubles as an LED-illuminated grading box featuring both daylight illumination and UV fluorescence detection along with a built-in grading tray.

• Set includes comparison stones for colors E, F, G, H, I, J, K, L, M and N in 1.0-ct. stone sizes—the largest range of reference available.
• A white and a yellow base metal solitaire ring stone holder allow you to compare masters against mounted stones.
• Each master CZ is laser-etched with the color it represents, making it easy to identify the stone color using only a 10X loupe and easy to avoid mixing up the masters.
• The set comes with a carrying pouch and a multi-voltage AC adapter with USB cord.
