Prime Standard
True Hearts & Arrows
Prime SOB Diamonds are true H&A BRD selections — Brilliant Round Diamonds, not broad “H&A-looking” marketing stones. The focus is optical alignment, symmetry, and real light behavior.

PRIME BRD = PRIME BRILLIANT ROUND DIAMOND
Craftsmanship is our foundation — not our ceiling.
SOB Diamond is the Shade of Brilliant allocated for a specific group of Prime BRD — Brilliant Round Diamonds — true Hearts & Arrows diamonds selected for better light performance than regular non-Hearts & Arrows diamonds.
Outlet Philosophy
Beyond Ordinary 3X
Many Prime stones are cut beyond traditional Triple Excellent expectations, while the lab report may remain conventional 3X to keep outlet pricing practical.
Craft Ladder
Not the Ceiling
SOB demonstrates where StarVinci craftsmanship begins. Beyond Prime SOB is the Harmonised Bonded Diamond reserved for the Treasure Bond Box™.
Why True H&A Defines Prime BRD
Hearts & Arrows is not decoration. It is optical discipline.
A Prime BRD — Prime Brilliant Round Diamond — uses true Hearts & Arrows cutting to show precise optical symmetry. Under a dedicated scope, a true H&A diamond displays eight balanced hearts and eight aligned arrows, revealing a level of cutting precision beyond ordinary brilliant round diamonds.
Maximum Light Return
Precise facet alignment helps light return through the crown instead of leaking away, creating stronger brightness, fire, and scintillation.
Balanced Contrast
The arrow pattern creates controlled bright and dark contrast, giving the diamond sharper visual life and more vivid sparkle.
Whiter, Larger Feeling
Stronger white-light return can make a well-cut H&A diamond appear brighter, cleaner, and visually larger than a standard-cut diamond of similar size.
True Prime Rarity
True H&A requires exceptional cutting control. Many stones are marketed as H&A-looking; Prime SOB focuses on genuine H&A BRD selection.
For SOB Diamond, Prime does not mean a marketing label. Prime means a true Hearts & Arrows Brilliant Round Diamond selected for real optical precision, practical outlet value, and stronger beauty than ordinary commercial 3X diamonds.
Prime is not a marketing label. Prime is a true H&A Round Brilliant Diamond.
SOB Diamond keeps the promise simple: stronger craftsmanship, practical certification choices, and better value for customers who want a beautiful diamond without paying for every premium layer.
