Calculator

Our pricing model is designed for straightforward precision. To estimate market value, simply enter the stone's shape, carat weight, colour, and clarity into the calculator. This comprehensive guide is specifically calibrated for officially certified gems, requiring an accompanying grading report from the IGI, GIA, or CDL. To ensure you are comparing top-tier quality, the pricing baseline also assumes the stone possesses an Excellent to Ideal cut, complete with excellent proportions and excellent symmetry.

Carat

Measures the physical weight of the precious stone, with one unit equating to 200 milligrams. This metric is the most direct indicator of the gem's overall size.

Cut

Refers to the precision of the facets, proportions, and symmetry crafted into the stone. This dictates how effectively light travels through the material, determining its overall brilliance, fire, and sparkle.

Colour

Evaluates the absence of natural tinting. The grading scale ranges from completely colorless - which generally allows the most light to pass through and holds the highest value—to stones with noticeable light yellow or brown hues.

Clarity

Assesses the internal and external purity of the stone. This involves checking under magnification for internal characteristics (inclusions) and surface defects (blemishes), with fewer imperfections resulting in a higher grade.
