29 Carat D-F Flawless-SI2 Pear Shape Diamond Necklace
This GIA-certified necklace comprises natural pear shape diamonds totaling 29.19 carats, with individual stones spanning D through F color and Flawless through SI2 clarity across a graduated sequence (Rosenberg ref. 6718). Assembling a matched suite at this total weight — each stone individually graded and selected for consistent face-up appearance — represents a level of curation rarely encountered in finished diamond necklaces. The graduated layout calibrates each stone’s size, color, and clarity to maintain visual coherence across the full length of the piece.
GIA Color and Clarity Grading: D–F and Flawless–SI2
On the GIA white diamond color scale, D, E, and F constitute the colorless range — stones that display no detectable body color under standardized grading conditions. This range is particularly demanding for necklace suites, where adjacent stones are viewed in close proximity and minor color variation between neighbors becomes immediately apparent. The clarity span from Flawless through SI2 reflects a size-appropriate approach: larger center stones carry the highest clarity grades, while smaller transitional stones graded SI1–SI2 remain visually indistinguishable from flawless material at typical necklace viewing distance.
Why Pear Shape for a Diamond Necklace
The pear shape — a hybrid of the round brilliant and marquise — produces an elongated silhouette that aligns naturally with the vertical drape of a necklace. Its single-pointed terminus and rounded shoulder allow consistent directional orientation stone-to-stone, producing a fluid visual line when stones are graduated in descending size from center to clasp. The modified brilliant facet pattern maintains strong light return across the full face-up surface, keeping each stone active across a range of lighting conditions.
Platinum Construction and Prong Setting
The necklace is handmade in platinum, which provides the structural density required to support individual prong settings across nearly 30 carats of total stone weight without adding visual bulk to the mount. Platinum’s 95% purity and inherent white color ensure the metal introduces no tint that could compromise the colorless character of the D–F stones — a consideration that yellow or white gold cannot fully address. Each pear shape is secured with directional prongs placed at the point and shoulder, exposing maximum table surface for unobstructed light performance.
