WHY LAB GROWN

The Business Case for Lab Grown Diamonds

Higher Margins

Lab grown diamonds offer 2-3x better margin per piece vs natural at comparable retail price points. The economics work for your business, not just your customer.

Younger Buyers

68% of engagement ring buyers under 35 actively consider lab grown. Your inventory should reflect your customer base, not your supplier's preference.

Bigger Stones, Same Budget

Offer your customers 2-3ct presence at the price of a 1ct natural. The upsell conversation changes when size is no longer the constraint.

TECHNICAL COMPARISON

CVD vs HPHT, What Matters at Wholesale

Both methods produce real diamonds, identical in chemical, optical, and physical properties to mined stones. The difference matters at wholesale because it affects pricing, availability, and what you should stock.

Frequently Asked Questions

Everything you need to know about sourcing lab grown diamonds wholesale.

What types of lab grown diamonds do you supply? expand_more
We supply both CVD (Chemical Vapor Deposition) and HPHT (High Pressure High Temperature) lab grown diamonds. Our CVD inventory covers 2ct to 20ct+ for statement pieces and high-carat collections. HPHT inventory focuses on 0.50ct to 1.50ct for high-volume retail categories like studs, eternity bands, and side stones. All stones are available in round brilliant and fancy shapes.
What is the difference between CVD and HPHT for retailers? expand_more
CVD diamonds dominate above 2 carats and are ideal for hero SKUs and solitaire collections. HPHT diamonds dominate below 1.50 carats with naturally strong colour and clarity, and since 2025, HPHT per-carat pricing has inverted below CVD for smaller sizes. Most retailers stock both: HPHT for volume, CVD for marquee pieces.
What certifications do your lab grown diamonds come with? expand_more
IGI certification is our standard for all lab grown diamonds. GIA certification is available on request at a higher per-carat cost. For melee and production runs where individual certification adds unnecessary cost, we offer non-certified parcels with our internal quality grading.
Can I order both CVD and HPHT in the same parcel? expand_more
Yes. We regularly build mixed parcels combining CVD and HPHT stones optimized for different product categories. A typical mixed order might include HPHT stones for your stud and eternity lines alongside CVD stones for your solitaire and statement collections.
How is lab grown diamond pricing structured at wholesale? expand_more
We provide transparent, market-linked pricing updated regularly. Lab grown pricing varies by method (CVD vs HPHT), carat weight, colour, clarity, and certification. We offer per-stone pricing for larger CVD diamonds and per-carat parcel pricing for HPHT volume orders. No hidden markups, no artificial urgency.
Can you supply matched pairs and calibrated sets in lab grown? expand_more
Yes. We specialize in matched pairs for earrings, calibrated sets for eternity bands and tennis bracelets, and graduated layouts for custom pieces. Matching is done by our in-house gemologists for colour, clarity, and cut consistency across every stone in the set.
What is the minimum order for lab grown diamonds? expand_more
Our minimum order is flexible and depends on product type. We offer sample parcels for first-time buyers starting at a small commitment so you can test quality, grading consistency, and logistics before scaling up.
How do you handle lab grown price volatility for bulk buyers? expand_more
Lab grown diamond prices have been declining and fluctuating as production scales globally. We provide transparent pricing updated regularly and offer price-lock options on confirmed orders for a defined delivery window. For ongoing supply contracts, we review pricing monthly and pass through market adjustments transparently.
