Cushion Cut Lab Grown Diamonds Wholesale

What Is the Cushion Cut?

Retailers and designers sourcing cushion cut lab grown diamonds wholesale will find Guru Diam's selection purpose-built for today's bridal and fashion jewelry market. The cushion cut combines old-world romance with modern brilliance, delivering the chunky fire and soft silhouette that consumers increasingly prefer over traditional shapes. Our IGI/GIA-certified cushion lab grown diamonds ship same-day from New York City, giving jewelers immediate access to both classic and modified cushion variants at competitive B2B pricing.

The cushion cut — historically known as the "old mine cut" — is one of the oldest diamond shapes in the trade, with origins tracing back over 200 years. The modern cushion retains the original shape's signature rounded corners and pillow-like silhouette while incorporating contemporary faceting technology that dramatically improves light performance. Today's cushion cuts feature 58 to 64 facets, depending on whether the stone uses a standard brilliant or modified brilliant faceting pattern.

Two primary variants exist in the wholesale market. The classic cushion brilliant (also called "chunky cushion") displays larger facets that produce bold flashes and prominent fire. The modified cushion brilliant adds an extra facet row below the girdle, creating a "crushed ice" appearance with more scintillation. Stocking both variants allows retailers to serve a wider customer base.

The ideal L/W ratio is 1.00 to 1.10 for a square cushion and 1.15 to 1.30 for an elongated rectangular cushion. Square cushions dominate engagement ring demand, while elongated cushions suit three-stone and east-west settings.

Why Cushion Cut Works Beautifully in Lab Grown Diamonds

The cushion cut is a fire-dominant shape, meaning it disperses light into spectral colors more aggressively than brilliance-dominant cuts like the round. Lab grown diamonds produced via CVD and HPHT methods deliver the crystal clarity and consistent internal structure that allows cushion facets to perform at their best — producing vivid rainbow flashes that consumers find captivating.

From a wholesale perspective, cushion cuts offer excellent rough-to-polished yield, translating to lower per-carat pricing compared to rounds. Lab grown cushions deliver a visually large, fiery stone at price points mined cushions cannot match. The shape also pairs exceptionally well with yellow gold and rose gold settings, aligning with current consumer metal preferences.

Best Jewelry Uses for Cushion Cut Diamonds

The cushion cut's romantic proportions and fire-heavy light return make it a versatile center stone for multiple jewelry categories:

• Engagement Rings: Cushion cuts are a top-three bridal shape. Halo settings amplify the stone's soft outline, while solitaire and three-stone designs showcase its fire. Square cushions work in four-prong and bezel settings; elongated cushions suit east-west or split-shank designs.
• Yellow & Rose Gold Settings: The cushion's fire characteristics complement warm metals beautifully. A G or H color cushion in 18K yellow gold appears warm, romantic, and intentional — a strong selling point for modern bridal customers.
• Vintage-Inspired Designs: The cushion's old mine cut heritage makes it the natural choice for vintage, Art Deco, and antique-style settings. Milgrain bands, filigree halos, and ornate gallery work all pair naturally with the cushion silhouette.
• Fashion Rings & Cocktail Rings: Larger cushions (2.00 ct+) in fancy settings create statement pieces that retail well in the fashion jewelry category.
• Stud Earrings: Square cushion studs offer a softer alternative to princess cuts, with rounded corners that are more comfortable and less prone to chipping.

Retailer Tips for Selling Cushion Cut Diamonds

Explain the Two Variants

Many consumers are unaware that "cushion cut" encompasses two distinct facet patterns. Show a classic chunky cushion alongside a modified brilliant (crushed ice) cushion side by side. Letting the customer discover their preference through direct comparison builds trust and increases close rates.

Sell Warmth as a Feature

Cushion cuts often look their best in G–J color, especially in warm metal settings. Position warmer color grades as an aesthetic choice rather than a compromise. This reframing increases margins because warmer colors cost less to source wholesale.

Show the stone under direct point-source lighting — the rainbow flashes are immediately visible and emotionally compelling. Customers who prefer fire over sparkle are natural cushion buyers.

Cross-Sell Settings

Present two or three mounting options with each loose stone to help customers visualize the finished piece and increase your average transaction value.
