68 Carat D-F VS1-SI2 Pear Shape Diamond Necklace
This necklace features a matched cluster of GIA-certified natural diamonds totaling 67.76 carats, composed of Pear Shape and Oval Cut stones grading D–F in color and VS1–SI2 in clarity (Rosenberg ref. 96176). A multi-stone cluster assembly at this total carat weight, drawing exclusively from the colorless to near-colorless range, represents a structurally rare configuration — stones of this combined scale and grade are rarely encountered in a single handmade platinum mounting.
GIA Color and Clarity Grades: D–F, VS1–SI2
GIA grades white diamonds on a color scale from D (colorless) through Z. The D–F range defines the colorless tier, the highest classification available, indicating an absence of detectable body color even under controlled laboratory conditions. Clarity grades span VS1 through SI2 across the cluster: VS1 stones carry inclusions invisible to the unaided eye, while SI2 inclusions remain at the threshold of eye-cleanliness — a range appropriate in a cluster context where the collective face-up appearance is evaluated as a unified composition rather than stone by stone.
Why Pear Shape and Oval Cut in a Cluster Format
Both Pear Shape and Oval Cut diamonds belong to the modified brilliant family, generating high light return across their curved outlines. In a cluster setting, combining these two silhouettes allows for close-contoured nesting that minimizes metal visibility between stones while preserving continuous surface brilliance. The elongated axes of both cuts contribute to a cohesive, uninterrupted visual field that a round-dominant cluster would not achieve at comparable total carat weight.
Handmade Platinum Cluster Construction
The mounting is handmade in platinum, the standard metal for high-carat diamond settings requiring long-term structural integrity. Platinum’s density and 95% purity ensure that the prongs and shared bezels securing each stone resist deformation over decades of wear — a critical factor in a cluster design where individual stone retention depends on continuous prong condition across the full necklace length.
