Cubic Zirconia vs Moissanite vs Lab Diamond: What Buyers Should Know

Cubic Zirconia vs Moissanite vs Lab Diamond: What Buyers Should Know For buyers comparing diamond alternatives, the choice comes down to three engineered stones: cubic zirconia offers the lowest cost, moissanite delivers extreme brilliance for a mid-range price, and lab-grown diamonds match natural diamonds in every measurable property at a fraction of the price. Based on 15 years sourcing from a Chinese manufacturer that spans lab diamonds, moissanite, and synthetic gemstones, here is a data-backed breakdown for B2B buyers. Key Takeaways Cubic zirconia costs under $20 per carat but scratches easily (Mohs 8.5) and loses transparency over time. Moissanite (Mohs 9.25) has a refractive index of 2.65–2.69, producing more fire than a diamond, at $300–$600 per carat. Lab-grown diamonds (Mohs 10, refractive index 2.417) are chemically identical to mined diamonds, priced 70–90% lower for comparable quality. For wholesale buyers, lab diamonds and moissanite offer better durability and c...

Cubic Zirconia Jewelry Buying Guide: Cut, Color, Size, and Setting

Cubic Zirconia Jewelry Buying Guide: Cut, Color, Size, and Setting Cubic zirconia offers the brilliance of diamond at a fraction of the cost, making it a practical choice for fine jewelry that looks high-end. The four factors you need to master are cut quality, color grade, stone size, and setting type — each directly affects how your finished piece performs under light and wear. Key Takeaways Cut quality determines light return and sparkle; avoid shallow or deep cuts that leak brilliance Color grades range from near-colorless DEF to warmer JKL, with DEF offering the whitest look Size is measured in millimeters for CZ (not carat weight like diamond); a 6.5mm round equals about 1 carat visually Setting choice impacts durability; bezel and channel settings protect edges, prong settings maximize light exposure For B2B buyers, sourcing from a manufacturer with tight tolerances ensures consistent cut and polish across batches What You Need Before Starting Before you order cubic z...
