How does Diamond Nexus Labs determine its pricing?
There are four factors to consider when pricing jewelry: gemstones, precious metals, design art/engineering, and artisanship. Essentially, this boils down to materials and labor. A ring with elaborate filigree workmanship but a relatively small gemstone may cost more than a simple ring with a much larger gemstone, because it took much more work to create it. Two rings with the same fundamental design and the same size stones can be priced differently because one may have more precious metal than the other, or may be more difficult to cast.
