At ARCA, we believe that only the finest diamonds deserve to become part of your story. Our in-house experts have created the TrueSpark™ selection process, a set of requirements even stricter than those of major grading labs like IGI. Our process begins with the basics: each diamond must have a IGI certificate and meet the highest grades in the 4Cs—cut, color, clarity, and carat. But this is just the first step. Next, we look closely at the diamond’s cut parameters. Details like table percentage, crown angle, pavilion angle, girdle thickness, and culet size are carefully checked to ensure every diamond falls within the ideal range, which guarantees the stone’s proportions are perfect for brilliance and beauty. After that, we use advanced tools like ASET and IdealScope to test each diamond’s light performance. Only diamonds that show outstanding brilliance and fire, reflecting and dispersing light beautifully, are selected to move forward. The fourth step is a detailed clarity check. Using a 10x loupe or microscope, we examine the location of any inclusions or flaws. We select only those diamonds whose imperfections are hidden at the edge or bottom, away from the visible center. Finally, we compare several diamonds with similar grades under different lighting—natural daylight, incandescent, and fluorescent. We choose the diamond with the most vivid fire, the brightest table, and the best symmetry. After this careful five-step selection, just l the finest diamonds are worthy of the TrueSpark™ standard. When you choose ARCA, you know you’re getting a diamond that truly stands out for its quality, beauty, and brilliance.
