I spent the morning with a factory I've worked with for years, running quotes on a ring stack. Same process, same 13 grams of silver, same CAD. I asked them to price it two ways.
First quote came back at $52. Second at $75.
That's a $23 difference, on a product that retails at either $150 or $250 depending on which spec you choose.
The entire identity of the piece lives in three line items
The factory didn't care which version I picked. They just read the sheet. $52 gets you cubic zirconia, light plating, and a standard polish. $75 gets you moissanite, heavier palladium and rhodium plating, and a more careful setting job.
The silver didn't move. The labor barely moved, $20 versus $22. The entire identity of the piece, premium or demi-fine, lives in three line items that add up to less than a dinner for two.
You get exactly what you spec, nothing more
That's worth sitting with, because most founders think the gap between premium and demi-fine is a different factory, a different supply chain, or some magic the demi-fine brand knows that you don't. It isn't. It's a spec sheet. The same hands make both.
You can't walk into a factory and ask for the best version at $52. They won't build you the best version. They'll build exactly what you spec, and if you don't know your materials, you'll get whatever's easiest for them to quote. The skill isn't finding the right factory. It's knowing your material costs well enough to spec for the category you actually want to sell in.
The right material is the one that matches your tier
Cubic zirconia at $2 isn't a compromise if you're building a premium silver line. It's the correct material for that tier. Moissanite at $18 isn't automatically better. It's the correct material if you're trying to occupy demi-fine shelf space and need the hardness and refraction to back up the story.
Same with plating. That $5 difference is the gap between a piece that shows wear in six months and one that holds up for years. The factory won't volunteer that. They plate to whatever micron count you write down.
So the line I'd build against this: know your SKU down to the gram and the micron before you ever ask for a quote. Silver, stone, plating, labor. If you can't split those out on your best-selling piece, you're guessing at your category. And guessing is expensive.
One caution
Don't spec moissanite and heavy plating just because you want to charge more. The customer isn't paying for your margin. They're paying for a product that honestly belongs in the tier you're claiming. If the materials don't match the story, the story falls apart the first time they take it to a jeweler for cleaning.
