A first-time buyer at a Tucson booth last spring held two 1 carat sapphires side by side: one round brilliant, one emerald step cut. Same color, same clarity, same origin. The step cut was 30% cheaper, and the buyer assumed it was a flaw. It was not. It was the cut yield and the faceting hours, and that gap is the single most under-appreciated price lever in wholesale gems.
Cut cost splits into three lines
When a cutter prices a stone, three things move the number. First is yield: what fraction of the rough survives the cut. A round brilliant wastes 50% to 60% of the rough on average, because the cutter must round the shape and align the facets. An emerald step cut follows the natural crystal shape and can keep 70% to 80% of the rough, which directly lowers the per-finished-carat cost. Second is faceting hours: a well-proportioned round brilliant on a sapphire takes 3 to 8 hours of skilled labor depending on size; a simple step cut takes 1 to 3. Third is demand premium: the round brilliant is the shape customers expect, and the market pays a 15% to 25% shape premium for it. The framework buyers use to compare proportions is the same cut-grading logic behind the GIA 4Cs, specifically the cut factor.
Why "poor cut" is often a smart buy
On a colored stone, the cut grade is more forgiving than on a diamond, because color is the purchase reason. A slightly shallow-step emerald sapphire that looks dull under a loupe can read beautifully in a closed-bezel setting, and it wholesales 20% to 40% cheaper than a "premium cut" of the same color. The trade method for buying on color rather than on cut grade is described in the per-carat trade method for loose gems, and the setting choice that rescues a soft-cut stone is in prong versus bezel buying tips.
Shape premium cheat sheet for buyers
Across a typical colored-stone parcel, the shape order from most expensive to least is: round brilliant, cushion, oval, emerald step, pear, marquise, trillion, freeform cabochon. The step and cabochon shapes are where the margin lives, because most retail buyers do not ask for them. A store that stocks a step-cut sapphire pendant at a mid wholesale ticket will often out-margin a round brilliant solitaire at the same ticket, because the customer is paying for color, not shape cachet. Compare the light-performance angle in cushion versus radiant light performance and the elongated-shape fit in pear versus marquise elongated cuts.
The incoming inspection step
Before you sign a parcel, weigh the finished stones against the expected yield for the cut. A parcel of 10 round brilliant sapphires that all come out heavier than expected per finished carat is usually a sign of over-weighted chunky cuts that leak light through the pavilion. A parcel of step cuts that all come out lighter is the normal result of good yield. Use a loupe and the lightbox method in the lightbox tray inspection method to separate good-cut economics from bad-cut economics.
Which gem cut costs the most per carat?
The round brilliant, because of rough yield loss and faceting hours. Expect a 15% to 25% shape premium over a step cut of the same color and clarity.
Is a step cut lower quality?
No. On colored stones, a step cut can show color better than a round brilliant. It reads dull under a loupe but alive in a setting.
Why do cabochons cost less?
A cab uses almost the whole rough, polishes in under an hour, and is a shape the market discounts despite being the right choice for asterism and chatoyancy stones.
Does cut matter more on diamonds or on color stones?
On diamonds, cut is a value driver. On color stones, color is the driver, and cut is a margin lever you can use in your buying.
How a cutter quotes you back
When you ask a cutter to quote a custom cut, expect three line items: the rough cost, the faceting labor, and the polishing time. A round brilliant on a 5 carat rough sapphire might quote at $120 to $250 in labor, while the same rough cut as a freeform cab quotes at $25 to $40. The labor line is where the margin decision happens, not the rough. If your retail customer pays on color, a step cut or cab delivers the same color at a fraction of the labor cost, and you keep the difference as margin rather than paying the cutter to produce a shape the customer does not ask for. Always ask for two quotes per parcel: one in the shape the customer names, and one in the shape the rough actually wants to become. The second quote is often the one that builds the relationship.

Frequently Asked Questions
How is wholesale jewelry priced?
By metal weight plus stone cost plus labor and plating. Ask for a line-by-line quote so you can compare suppliers on the same basis.
Why do two suppliers quote very different prices?
Metal purity, plating thickness, stone grade and QC standard differ. A cheaper quote usually means thinner plating or lower stone clarity.
What volume discount should I expect?
Typically 5–12% from 500 to 2,000 pieces, and better terms on repeat programs. Ask for the tier table before you commit.
What are the payment terms?
30% T/T deposit, 70% against the bill of lading. Sample costs are credited against the bulk order.
