About Lime Diamonds
Lime color can vary from an unripe lemon with greenish tint (greenish-yellow) to the bright color of grass, or leaves, which is yellowish-green. In the case of greenish-yellows and green-yellows, the green fluorescence in the stone is the primary cause for the color. On the other hand, when talking about yellow-green and yellowish-greens, in most cases, the color is caused by natural irradiation.
When placed in daylight the fluorescence is accentuated giving the stone the appearance similar to highlighters. The stronger the green fluorescence, the more the diamonds take on an apple color. Whereas it is not a pure color, they are considerably rarer than yellow diamonds and due to the lack of information about them, they are extremely underpriced.
The only mines that producing lime coloured diamonds are situated in South America, Indonesia, and Africa. Considering their beauty, and rarity, natural lime colored diamonds are extremely good value for money.
