Jacobijoux's discerning eye is drawn only to the most exquisite diamonds, which serve as the focal points of our distinctive engagement rings, reflecting his artistic vision and inspiring creativity.
Each stone is carefully inspected by a Jacobijoux diamond expert to ensure it meets our high quality standards.
We meticulously choose diamonds from the top tier of each aspect of the 4C’s, which are the universally recognized benchmarks of quality established by The Gemological Institute of America (GIA). All our diamonds undergo evaluation by the GIA, an impartial global authority, to ensure their quality.

The cut of a diamond refers to its proportion and the precision of its facets, which are crucial factors determining the stone’s sparkle and brilliance. In our engagement rings, we exclusively use diamonds with an “excellent” cut grade, and occasionally a “very good” cut grade, ensuring exceptional quality. Fancy-shaped stones, on the other hand, are assessed primarily for their polish and symmetry.
At Jacobjijoux, our specialty lies in round and cushion-shaped diamonds, including our distinctive DY Signature Cut™. This patented cut features well-defined corners and a graceful curvature along the diamond’s edges. Each Jacobjijoux diamond is meticulously cut to enhance its beauty, even if it requires sacrificing more of the original rough diamond.
The 4 C’s—Color
What You Can’t See
Jacobijoux’s engagement diamonds span from D (colorless) to F on the diamond color grading scale. Each selection by Jacobbijoux is meticulously chosen to be either entirely colorless or very close to it, making every piece a coveted rarity and a symbol of the promising future ahead. In our Wedding Collection, Jacobijoux exclusively opts for untreated, natural diamonds.
Moreover, Jacobijoux provides a diverse range of engagement rings featuring center stones made of sapphire, emerald, and ruby, alongside Fancy Intense yellow diamonds. These options cater to brides seeking to express their love with vibrant and colorful statements.

In general, diamonds with fewer distinct characteristics are considered rarer. When a diamond is described as “flawless,” it means it lacks any unique characteristics such as inclusions.
The term “flaw” is commonly used to denote these distinctive traits and gauge the diamond’s rarity. In crafting our engagement rings, Jacobjijoux exclusively chooses stones from the highest clarity grades, ranging from IF (Internally Flawless) to SI1 (Slightly Included).
The 4 C’s—Carat
Choose Better, Not Bigger
Jacobjioux’s engagement diamonds start at 0.30 carats and increase in weight, offering a comprehensive range of options. It’s important to understand that carats measure mass—where one carat equals 0.20 grams—rather than size. Whether you prefer something discreetly intimate or dazzlingly grand, Jacobbjioux ensures there’s a stone to perfectly match every bride’s unique taste.
GIA Reports
Every diamond featured in our engagement rings comes with a comprehensive grading report from the Gemological Institute of America (GIA), a renowned independent authority on quality. Each GIA grading report is assigned a unique number, meticulously detailing the characteristics of the diamond and providing a thorough assessment of the 4 C’s of diamond grading.
Furthermore, the unique report number is laser inscribed on the girdle of the diamond, creating a direct link between the stone and its corresponding GIA grading report. This ensures transparency and authenticity in every aspect of our diamond selection process.
