Sub-translucent opals are represented in a wide spectrum of colors.

There are many shades of citrine which can be seen in nature (such as the yellow quartz variety). We produce a few of the most popular ones: green-gold (with a slight greenish tint), canary (bright yellow), orange (orange-yellow) and Madeira (dark red-yellow). Nanosital #144 can also be used as a yellow sapphire imitation.
