When selling moissanite necklaces on Alibaba.com, material selection is the single most important product attribute that determines your target buyer, price point, and market competitiveness. For Southeast Asia exporters looking to expand globally, understanding the material landscape is not optional—it's essential for survival in the B2B jewelry market.
Moissanite itself is a lab-created gemstone with a Mohs hardness of 9.25, second only to diamond (10.0). This exceptional durability makes it ideal for everyday wear jewelry [2]. However, the setting material—the metal that holds the moissanite stone—is what buyers scrutinize most carefully when making bulk purchasing decisions.

925 Sterling Silver dominates the moissanite necklace market for good reason. It offers the best balance of affordability, appearance, and durability for the majority of B2B buyers. According to Charles & Colvard, sterling silver contains 92.5% pure silver with 7.5% alloy metals (usually copper) for strength [3]. However, pure silver is too soft for jewelry, which is why the alloy is essential.
Rhodium plating is a critical upgrade that Southeast Asia exporters should consider offering. This thin layer of rhodium (a platinum-group metal) provides additional tarnish resistance and gives silver a brighter, whiter appearance similar to white gold or platinum. For daily wear moissanite necklaces, rhodium-plated silver is the industry standard recommendation [2].
