The historic term water describes which property of diamonds?

• A. Color or transparency
• B. Clarity
• C. Carat
• D. Fluorescence

Answer: (A)

The historic term water describes how a diamond appears in terms of colorlessness and light transmission. In old gem-trade language, “water” (often used as “water white”) referred to a stone that looks exceptionally colorless and very clear, with high transparency that lets light pass through easily and evenly. That makes it a description of color and how transparently the diamond ends up looking to the eye. It isn’t about carat (weight), fluorescence (glow under UV), or clarity (inclusions), which are separate properties. So the best answer is color or transparency.
