The best color of sodalite is typically considered to be a deep, rich blue with well-defined white veins. High-quality specimens with this coloration are considered to be the most desirable and can command a premium price. However, personal preference plays a large role in determining the "best" color of any gemstone, and some people may prefer lighter or more uniform sodalite blue color shades. Ultimately, the best color of sodalite is the one that appeals most to the individual buyer.
