TrueSpark™: The ARCA Diamond Standard
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.

How to Clean Your Ring: Simple Tips for Lasting Shine
Everyday activities can leave your ring covered in oil, dirt, and dust, which may reduce its sparkle and hide the diamond’s brilliance, which also harm the plating or delicate surfaces of your ring. Regular cleaning protects your diamond’s shine and helps prolong the life of both the stone and the ring.
How to Clean Your Ring at Home
Cleaning your ring at home is simple and doesn’t require any special tools. Start by soaking your ring in a bowl of warm water. Add a small amount of mild dish soap, body wash, or a jewelry cleaner—but avoid any moisturizing products, as they can leave a coating on your ring.
After soaking for about 15-20 minutes, gently scrub the ring with a clean, soft-bristled toothbrush to remove any remaining dirt. Pay special attention to the underside of the stone, where grime can build up. When you’re done, rinse the ring with clean water and let it dry naturally on a paper towel or soft cloth.
Other Tips and Precautions
For best results, clean your ring every one to two weeks. Avoid using harsh chemicals like bleach, alcohol, toothpaste, or ammonia, as these can corrode the plating or damage the stones. If your ring is plated, be especially gentle—excessive scrubbing can wear away the surface layer.
With these simple steps, your ring will keep its sparkle and beauty, letting you enjoy its brilliance every day.
How to Choose the Perfect Lab-Grown Diamond Ring
Choosing a diamond ring is a special journey, whether it’s for an engagement, anniversary, or simply a personal treat. Lab-grown diamonds offer a sustainable and cost-effective alternative to mined diamonds, without compromising on beauty or quality. Here’s a step-by-step guide to help you select the perfect lab-grown diamond ring.
Diamond Shapes
Round
The round diamond is the most popular and classic shape, known for its exceptional brilliance. With 58 facets, it maximizes light reflection, making it a timeless choice for any occasion.
Radiant
The radiant diamond combines the elegance of a square or rectangular shape with the brilliance of a round cut. Its trimmed corners and 70 facets create a stunning, fiery sparkle.
Princess
The princess diamond is a modern favorite, featuring a square shape with pointed corners. Its unique cut combines brilliance and contemporary style, making it a versatile option.
Cushion
The cushion diamond, often referred to as a "pillow" shape, blends a square cut with rounded corners. Known for its vintage charm, it offers a softer, romantic brilliance.
Heart
The heart-shaped diamond is the ultimate symbol of love. Its distinctive shape and complex craftsmanship make it a romantic and unique choice, with 59 facets for a brilliant sparkle.
Oval
The oval diamond offers a classic silhouette with an elongated shape. Its rounded edges and brilliant facets enhance its sparkle, creating an elegant and flattering appearance.
Pear
The pear-shaped diamond, resembling a teardrop, combines the best of round and marquise cuts. Its unique shape makes it ideal for those seeking a distinctive and graceful look.
Emerald
The emerald diamond features a rectangular shape with step-cut facets, emphasizing clarity and elegance. Its large, open table highlights the diamond's natural beauty.
Marquise
The marquise diamond, with its elongated shape and pointed ends, creates an illusion of greater size. Its striking silhouette and brilliant facets make it a bold and dramatic choice.
4Cs of Diamonds
The fundamental process of determining the worth of a diamond revolves around understanding the 4Cs, a set of standards that enable gemmologists to objectively assess the quality of such precious stones. The "4" signifies the number of critical factors, while each "C" represents the first letter of an essential criterion. The desirability and market value of a diamond are largely determined by these key factors.
How are Diamonds Made in a Lab?
Lab-grown diamonds are produced in controlled environments that simulate the natural conditions under which diamonds form deep beneath the Earth’s surface. There are two primary techniques used to manufacture these diamonds: Chemical Vapour Deposition (CVD) and High Pressure High Temperature (HPHT). Both methods are highly effective at producing authentic diamonds of exceptional quality, indistinguishable from those found in nature.
What are Lab Grown Diamonds?
Lab-created diamonds are genuine diamonds in every sense of the word. They possess the same chemical composition and physical properties as diamonds that are naturally mined from the earth. The primary distinction between the two lies in their origin. However, lab-grown diamonds offer several significant advantages: they come at a lower price point, are produced under more ethical conditions, and have a smaller environmental impact.
