Description
Date: c. 1680-1700, late 17th century
Materials: natural earth mined diamonds, solid 22k yellow gold (unmarked; tested with electronic gold tester and nitric-muriatic acid)
Workmanship origin: Western Europe (possibly south Netherlands / Flanders)
Weight: 10.6 grams
Height: 43 mm
Width: 35.6 mm
Dimension of diamonds: 15 total (measured in mm) — 4.4 x 3.4, 4.75 x 3.75, 5.5 x 4.75, 4.25 x 4, 4.6 x 4.25, 3.75 x 3.2, 3.4 x 2.75, 3.75 x 2.6, 4.25 x 3, 3.4 x 3, 3.8 x 3.25, 2 x 2, 2.4 x 1.8, 2.4 x 2.2, 2.6 x 2
Approx. weight of diamonds: estimated 3.04 ctw (largest five being 0.59, 0.38, 0.33, 0.31, 0.26)
Condition: some tarnishing to the silver foiling of 2-3 diamonds. Age-related abrasions to some diamond facet junctions (loupe visible). Some natural flaws: one diamond with a surface-reaching feather that links to a cavity, two diamonds with a slight bezel to a table corner (instead of chip, may be an indented natural). One diamond is slightly sunken in within its bezel. This cross came to me with some heat-related gold discoloration to the center; my jeweler was able to restore the original appearance with a non-invasive pickle. Overall this piece is in a fairly pristine condition for its age, with no replacement stones and no damage or repair. Details are still crisp, and delicate rub-over collets are well-preserved.
