2025 Lab-Grown Diamond Price Guide: The Advantage of Sourcing Direct

As we enter 2025, the lab-grown diamond market continues to stabilize, making it an incredible opportunity for independent jewelers and designers. However, one question remains: Are you overpaying for your stones? Many jewelers in North America and Europe still buy from local wholesalers. While convenient, this supply chain adds multiple layers of markup. At Kunlun Growth, we want to be transparent about the pricing structure of HPHT diamonds.

The Supply Chain Markup

Typically, a lab-grown diamond travels through 3-4 hands before reaching a jeweler:

Step 1: The Manufacturer (That's us in China) - Grows the crystal.
Step 2: The Cutting Factory - Polishes the stone (Often in India or China).
Step 3: The Global Wholesaler - Imports and stocks the inventory.
Step 4: The Local Dealer - Sells to you with a markup.

By the time it reaches you, the price has often increased by 50% to 100%.

The "China Direct" Advantage

China produces over 90% of the world's HPHT (High Pressure High Temperature) diamonds. This technology is superior for creating colorless (D-E), high-clarity (VVS) stones ranging from 1 to 10 carats. By sourcing directly from Kunlun Growth, you are buying from the source hub. We estimate that our partners save an average of 20-40% compared to buying from US-based inventory lists.

2025 Price Trends for HPHT

This year, we are seeing strong demand for:

Shapes: Round Brilliant and Oval continue to dominate.
Color: The market is shifting strictly to D-E Color. Lower colors (G-H) are becoming harder to sell, which gives HPHT a huge advantage over CVD.
Clarity: VVS2 and VS1 are the "sweet spot" for value.

Our Minimum Order Quantity (MOQ)

Unlike massive industrial factories that require you to buy thousands of carats, Kunlun Growth is designed for jewelers. We have NO strict MOQ for polished stones. Whether you need a single 3-carat D-Color centerpiece or a parcel of 100 stones, we can fulfill your order with the same factory-direct pricing.
