Pear-shaped moissanite is one of the most shape-dependent cuts in a wholesale assortment. A 7x5mm pear and a 10x7mm pear are not just different sizes; they are different products aimed at different customers. Stock the wrong mm range and you sit on inventory for a year. Stock the right range and the stones reorder before you realize the tray is empty. Below is the practical grid we use when advising buyers, built from the movement we see across engagement, pendant, and earring accounts.
First, a quick orientation. Pear moissanite is measured by length times width, in millimeters. The point is the tip, the rounded end is the head. A well-proportioned pear runs about 1.45 to 1.65 times longer than it is wide. Outside that range, the stone either looks stubby or stretched. When you build a stocking grid, you are really building a matrix of two axes: mm size and the price tier of the finished piece the stone will go into.
The core stocking sizes
The volume center of pear demand sits between 7x5mm and 10x7mm. These three sizes alone cover the majority of pear engagement rings, pendants, and drop earrings. The 7x5mm pear sits at roughly 0.75 to 0.85 carat diamond equivalent and is the entry point for customers who want a named shape without a center-stone budget commitment. The 8x5mm and 9x6mm pears are the workhorses. The 9x6mm in particular is the size that photographs beautifully in a solitaire and still feels wearable on a daily basis.
The 10x7mm pear is the statement tier. It pairs well with a thin halo and reads like a much more expensive stone, because pear shape face-up is generous. It is also the size most likely to carry a visible bow-tie if the cut is poor, so QC here matters more than at smaller diameters. We cover the symmetry and bow-tie tolerance in the pear QC tolerance guide; read it before you buy a large 10x7 parcel.
Sizes that sit on the shelf
Two ranges consistently underperform and should be treated as made-to-order. The first is the tiny 5x3mm to 6x4mm range. These pears show up in children's jewelry, midi rings, and earring jackets, but the demand is fragmented and price-sensitive. Unless you specifically serve a bridal earring program, do not tie up cash in small pears. The second is the oversized 12x8mm and 14x9mm range. These are striking, but they sell once per store per year, usually to a customer who is treating themselves. Stock one at most, on approval, and reorder on demand.
Pairs for earrings
Half of pear demand comes in pairs. When you stock pears for earring work, buy matched pairs from the same parcel, not two singles from different trays. The face-up color and the symmetry will drift between parcels, and a customer holding two earrings to a white sheet will spot it. Our matched pear pair guide explains how to grade the head-to-tip orientation and the mirror symmetry that earring customers expect.
Depth per size: how many to buy
For an independent jeweler, a sensible opening buy is two stones each of 7x5, 8x5, and 9x6, and one stone of 10x7. That is seven stones total. It sounds thin, but it is enough to build samples and quote to customers. Once the 9x6 size reorders twice, add depth there and only there. Resist the urge to fill every mm slot; shallow, fast-turning inventory beats deep, slow inventory every time on a shaped stone.
Pricing tracks size on a curve, not a straight line. A 9x6mm pear costs more per stone than a 7x5mm, but the retail markup on the larger piece is healthier because customers comparing against a mined diamond anchor on carat, not on wholesale cost. The current price bands are broken out in the pear moissanite price guide; match your stocking grid to those bands and you will always know your margin before a customer asks.
The honest summary is simple: pears are not a "one size fits all" shape. Build the grid around 7x5, 8x5, 9x6, and 10x7, treat everything below and above as special order, and let reorder data tell you when to deepen a size. That discipline keeps your pear tray turning instead of gathering dust.
Seasonality also matters. Pears skew bridal in the spring and summer engagement season, and skew pendant and earring work in the November gift window. If your customer base is heavily bridal, weight the 8x5 and 9x6 buy toward March. If it is gifting-led, add a few extra matched pairs of 7x5 in October. The mm grid does not change; only the depth per size shifts with the calendar. Review the tray twice a year and rebalance before demand peaks rather than after. Treat the tray as a living grid, not a one-time buy.
