While 2024–2025 was the era of the 2-carat stone, B2B wholesale orders for March 2026 delivery are showing a massive surge in 3.5ct to 4.5ct center stones as the primary choice for “Spring Bridal” collections.

B2B Market Intel Insights:

• Consumer “Size Creep”: As LGD prices have stabilized at lower levels, consumers are not pocketing the savings; they are “trading up” in size. The 4-carat LGD has become the new “aspirational standard” for the $5,000–$7,500 retail price point.

• Setting the Challenge: This shift is creating a B2B bottleneck for high-quality, large-carat mountings. Manufacturers of “heads” and “settings” are scrambling to update their stock catalogs, as traditional “standard” settings are often too small for these larger LGD crystals.

• The “Table Percentage” Warning: With the rush to grow larger stones, some wholesalers are pushing “Deep” or “Spread” stones to hit the 4-carat mark. Retailers need to be warned to check cut proportions (Table/Depth) more carefully than ever to avoid “fish-eye” or “nail-head” effects in these larger sizes.

Intel Action Item: Retailers should audit their mounting inventory. If your store only stocks settings for 1–2ct stones, you are effectively “merchandised out” of the most profitable segment of the 2026 Spring bridal market.
