Whether you’re looking for vibrant green or yellow diamonds, delicate pink diamonds that are perfect for a romantic gift, stately gray or black diamonds, or chameleon diamonds that are sure to inspire amazement, Astteria offers the highest quality of rare coloured diamonds in a variety of hues, tones, saturations – and price points.
Our coloured diamonds for sale come in a variety of shapes, including classic shapes such as round, princess, and marquise, as well as in a variety of non-conventional shapes that maximize the stone's natural colour.
Our diamonds are of the highest quality and extremely rare, having been created by organic processes over millions of years. Carefully selected for their quality, our natural coloured diamonds are evaluated based on a standardized grading scale that measures the cut, colour, clarity of each stone.
As colour values are the most important factor in determining prices for coloured stones, our diamonds are stringently measured by standardized colour parameters. These include measurements of the hue (which represents the stone’s primary shade) tone, (which measures the penetration of light), and saturation (which gauges the intensity of the colour.)
Our diamonds are inspected by the world’s leading gemological institutes and come with a certificate that testifies to the origin and authenticity of each stone, in addition to listing the diamond’s unique characteristics and colour qualities.
