Makeables — The Rough That Will Yield a Single Polished Stone
Makeables — The Rough That Will Yield a Single Polished Stone
The dealer-and-cutter category for rough capable of producing a saleable cut gem
In the rough-gemstone trade, makeables is the conventional dealer-and-cutter shorthand for rough material that will yield at least one saleable polished stone after the standard sequence of sawing, preforming, faceting, and polishing. The term implies that the rough is large enough to produce a cut stone of commercial size, clean enough to produce a stone of acceptable clarity, and well-formed enough to support the cutting plan without excessive material loss to fractures, inclusions, or shape constraints. Makeables are distinguished from sawables (rough requiring division into multiple pieces, each of which may be a separate cut stone) and from material that is too small, too included, or too fractured to yield a saleable stone at all.
The category in the rough trade
The rough-gemstone trade — particularly in the diamond rough market and the major coloured-stone rough markets in Bangkok, Antwerp, Tel Aviv, and the principal source-country trading centres — uses a vocabulary of rough categories that organises material by its cutting potential. Makeables sit within this vocabulary as the category of rough that will yield a single primary stone, with the cutter's plan typically focused on maximising the size and quality of that one stone within the constraints of the rough's shape, clarity, and orientation.
Sawables, by contrast, are larger pieces of rough that the cutter will divide along the grain (in diamond) or along advantageous orientations (in coloured stones) into multiple separate pieces, each of which is then worked as a separate cut stone. The sawing decision is one of the principal valuation considerations in larger rough — the way the rough is divided substantially affects the total value of the recovered cut stones — and the dealer's evaluation of the sawing potential of a particular piece of rough is one of the most important inputs into the rough purchase decision.
The makeable evaluation
Evaluating a piece of rough as a makeable involves several considerations. The size and shape of the rough must support a viable cutting plan, with the orientation of the rough relative to the desired cut shape determining how much material will be lost to faceting and how much will be retained in the finished stone. The clarity of the rough — the position and extent of inclusions, fractures, and other defects — determines whether the cutter can avoid the defects in the cutting plan or whether the defects will appear in the finished stone and reduce its value.
The colour and orientation considerations vary by species. For diamonds, the cutter's principal concerns are the cleavage planes (which support the sawing decision but constrain the cutting orientation), the inclusion positions, and the production of the standard cut shapes (round brilliant, princess, cushion, oval, and so on) at competitive proportions. For coloured stones, the cutter's principal concerns include the orientation of the colour zoning (with the desired colour saturation typically requiring a particular orientation of the cut stone relative to the rough's colour distribution), the position of inclusions, and the species-specific cutting conventions.
The price implications
The classification of a piece of rough as a makeable, a sawable, or as material below the makeable threshold has direct price implications in the rough trade. Makeables price per carat in the rough typically reflects the dealer's projection of the recovered cut-stone value, less the cutting cost and a margin for the cutter's risk and return. Sawables price typically reflects a more complex projection that accounts for multiple cut stones from the divided rough. Material below the makeable threshold — too small, too included, or too fractured to yield a single saleable stone — typically prices at very substantial discounts and may be sold as accumulating parcels for melee production or as material for industrial applications.
The price differentials between these categories are substantial, with makeable rough commanding multiples of comparable below-threshold material at the same gem species. The accurate evaluation of rough at the point of purchase — the assessment of which pieces are makeables, which are sawables, and which are below threshold — is one of the principal skills in the rough trade and one of the principal inputs into commercial success in the rough business.
In the trade
For dealers and cutters in the rough trade, makeables is one of the most-used terms in working evaluation and parcel discussion. The term conveys a clear working assessment of a piece of rough's cutting potential and informs the price discussion at the point of purchase. The combination of the makeable evaluation, the species-specific cutting considerations, and the dealer's accumulated experience supports the working operation of the rough trade across the major coloured-stone and diamond markets.
