We evaluate each diamond using the highest standards for Cut, Clarity, Color, and Carat Weight. Our commitment to sourcing the best means we focus on diamonds that excel in all four categories. This results in diamonds with superior brilliance, minimal imperfections, and exceptional overall beauty. By setting thresholds that exceed industry averages, only stones of the highest quality make it into our selection.
Each diamond we select comes with certification from a trusted body, primarily the GIA (Gemological Institute of America). GIA certification is the gold standard in the industry, providing an unbiased and thorough analysis of a diamond's characteristics. This credential confirms the stone's authenticity, precise quality, and grading. Additionally, we also consider diamonds that meet ethical and environmental standards, ensuring that each stone is not only beautiful but responsibly sourced.
Our dedication to innovation and sustainability means we prioritize lab-grown diamonds created using the CVD (Chemical Vapor Deposition) method. This advanced process allows for precise control over the diamond’s growth, resulting in fewer defects and inclusions compared to other methods like HPHT. By selecting CVD diamonds, we ensure that our clients receive diamonds that exhibit the highest standards of purity and brilliance, often outshining other lab-grown alternatives.
We also apply strict ethical criteria to our selection process. Each diamond is carefully vetted for conflict-free origins, and we seek out diamonds that meet our sustainability standards. Our commitment to responsible sourcing ensures that the diamonds we offer align with modern values around ethical consumption. The region that produces the most diamonds in the world uses primarily the HPHT grow method and their electricity is produced in excess of 60% by coal. By not supplying HPHT stones we can ensure that our stones are grown using solar and other renewable energies.
Our long-standing relationships with trusted merchants allow us to access an exclusive pool of diamonds that are not available to the general market. With our industry expertise and deep connections, we are able to filter this selection further, ensuring we have access to the very best diamonds. By applying our knowledge of the market and quality standards, we identify and hand-pick only the finest stones.
By applying these stringent filters, combining advanced certification, sustainability standards, and industry expertise, we can confidently say that the diamonds we offer represent the top 1% of stones available from our merchants. This exceptional level of curation ensures that every diamond from Kate & Kole is among the finest available anywhere.
