4 min read

The quality of a lab-grown diamond jewel is often determined long before the final piece is completed. It begins with the selection of each diamond and continues through every detail of craftsmanship - from proportions, prong placement, and settings to the harmony of precious metals and refined design. At RAGAZZA, lab-grown diamonds are valued not simply for their size or grading, but as an integral part of fine jewelry.

From diamond selection, data analysis, expert evaluation, certification standards, and in-person inspection to jewelry design, craftsmanship, and final quality control, RAGAZZA follows a comprehensive set of standards to achieve exceptional clarity, brilliance, refinement, and lasting beauty. The following are the 11 standards that define RAGAZZA's premium lab-grown diamonds.

1. Eliminating Diamonds That Compromise Luxury Quality

RAGAZZA’s diamond selection begins with elimination. Before any lab-grown diamond is considered, it is carefully inspected for visual issues such as brown or green undertones, milky appearance, haze, grayness, darkness, or a lack of transparency. Certain HPHT-grown diamonds may also exhibit a blue tinge, while some inclusions can appear artificial and reduce the diamond’s natural purity. These characteristics are not always reflected in grading reports but can significantly affect the diamond’s overall appearance. Only diamonds with exceptional clarity, transparency, and natural beauty proceed to the next stage.

2. Expert Visual Inspection & Optical Evaluation

D Color, VVS, 3EX diamond does not always guarantee outstanding brilliance. RAGAZZA evaluates every diamond through expert visual assessment, examining brightness, fire, transparency, and overall light performance. When required, professional tools such as the ASET Scope and H&A Scope are used to analyze light leakage, light distribution, cut symmetry, and Hearts & Arrows precision, ensuring only diamonds with superior optical performance are selected.

3. Selecting Better Diamonds with DAII™

After the initial screening, RAGAZZA applies the DAII™ Diamond Quality Index to compare diamonds of the same 4C grade and similar price. By analyzing 16 key parameters, including proportions, angles, fluorescence, symmetry, polish, and certification DAII™ identifies diamonds with better light performance, proportions, and overall brilliance.

5. Dedicated Standards for Fancy-Colored Lab-Grown Diamonds

For colored lab-grown diamonds, RAGAZZA focuses on color quality rather than color names. Fancy Intense and Fancy Vivid grades are carefully evaluated for tone, saturation, balance, and overall elegance, ensuring each diamond complements its jewelry design beautifully.

6. Crafted to High Jewelry Standards

Every RAGAZZA diamond is set in 18K gold or platinum and paired with carefully selected accent diamonds. From setting proportions to metal finish and structural balance, every detail is refined to maximize beauty, durability, and sophistication.

7. Fine Craftsmanship in Every Detail

8. Bespoke Jewelry Design

RAGAZZA transforms each diamond into a meaningful jewelry creation. Whether for engagement rings, anniversary gifts, or personal milestones, every design is tailored to the client's style, story, and preferences.
