Diamonds Buying Guide

Our specialty is coloured diamonds which range in colour through pink, green, yellow, orange and blue. We offer these stones with a carat weight of between 1.50 to 2.50 carats and clarity from VVS2 to S1. Tone refers to the lightness or darkness of a diamond’s colour and is a critical aspect in evaluating the overall appearance of a fancy colour diamond. The tone scale ranges from Fancy Light, Fancy, Fancy Intense, Fancy Vivid, and Fancy Deep. The tone scale provides a nuanced framework for assessing the richness and depth of colour of fancy colour diamonds. A Fancy Light tone exhibits a delicate, subtle coloration, while Fancy Vivid strikes a balance between vividness and sophistication. Stepping up, Fancy Intense showcases a more pronounced and vibrant hue, commanding attention with its radiant presence. 4C Diamonds also sells a range of colourless diamond rings with a stone size from 1.50 to over 2.00 carats. These are mounted in thee most popular ring settings. The diamonds supplied range in colour from D to F and with a clarity grading of F (flawless) to VVS1 and each stone is certificated by IGI (International Gemological Institute).
