1.25ct Cushion Amethyst

Amethyst is the purple variety of quartz and has been treasured since ancient times. Its color ranges from light lavender to deep violet, caused by iron impurities and natural irradiation.

Our gemologists hand-select each stone, examining hundreds to find those with the perfect combination of color, clarity, and character that meet Giraux standards.

Color is the most important quality factor for colored gemstones. It's evaluated based on three components: hue (the basic color), saturation (the intensity of the color), and tone (lightness or darkness).

The most valuable gemstones display vivid, saturated colors that are neither too light nor too dark, allowing the stone's natural beauty to shine through.

Carat is the standard unit of weight for gemstones, with one carat equaling 200 milligrams. Because different gemstones have different densities, two stones of the same carat weight may appear different sizes.

For example, a one-carat sapphire will appear smaller than a one-carat diamond because sapphires are denser. What matters is how the stone appears when set in jewelry.
