Modernizing Old-Cuts

We provide the service of re-cutting vintage diamond cuts into modern ideal cut specifications. The question often arises as to whether modernizing old-cut diamonds is sensible and worthwhile? It is important to weigh up all the factors which influence positively and negatively the value of the stone before and after re-cutting.

From what size is the modernizing of an old-cut viable?

Modern-cut brilliant should be at least as valuable as the old-cut stone plus the cutting cost. The minimum size for an old-cut brilliant should be at least 1.00 ct. It is only with top quality stones that re-cutting might be advisable for 0.50 ct.

Can color and clarity grades be improved by modernization?

The color of a clumsily proportioned old-cut diamond, when recut to ideal proportions with maximum yield of light and dispersion, can be improved by one to two grades. It might be possible to remove inclusions which are situated in the old-cut near the surface of a high crown, near a pavilion facet or near the girdle, so that the "new" brilliant can also in this way be graded one or two grades higher and thus be evaluated higher.

Is there any risk when re-cutting an old-cut?

Yes, especially if the brilliant shows inclusions in the form of cleavages or fractures which could expand under pressure and temperature during cutting. Even diamonds without these features or with very small inclusions can - albeit in rare cases - develop cracks because of inner tension which can then expand and "blind" the whole stone. 

We will point out all the risks to our customers, as it is the customer who has to bear any loss or damage.
