13 Carat H SI2 Pear Shape Diamond Ring
The center stone is a 13.34-carat H SI2 Pear Shape natural diamond, GIA certified (Rosenberg ref. P-12051). Pear Shape diamonds exceeding 13 carats with sufficient symmetry and proportion to perform well face-up are rarely encountered in the commercial market — at this weight, stones achieving consistent optical performance represent a structurally limited share of annual GIA submissions regardless of demand cycles.
GIA Color and Clarity: H SI2 on the D-to-Z Scale
GIA grades white diamonds on the D-to-Z color scale; H falls within the near-colorless range, where body color is not detectable to the unaided eye face-up, particularly at a carat weight where the stone’s depth and spread diffuse any residual warmth. SI2 clarity denotes slight inclusions that remain invisible without magnification and carry no effect on light transmission or structural integrity in a diamond of this size and facet arrangement.
Why Pear Shape at This Scale
The Pear Shape is a hybrid cut — combining the modified brilliant facet pattern of a Round with the elongated outline of a Marquise — that maximizes perceived face-up spread relative to carat weight more efficiently than any other brilliant form. At 13-plus carats, the shape also creates a pronounced visual elongation along the finger, a characteristic that has made Pear Shapes the preferred choice for large center stones across both contemporary and historically significant pieces. The tapered point requires a reinforced tip prong, which the platinum mount incorporates as a structural necessity rather than a stylistic detail.
Three-Stone Platinum Setting with Trillion Side Stones
Two matched Trillion-cut side diamonds, 3.11 carats total weight, flank the center stone in a handmade platinum three-stone mount. Trillions provide a triangular geometric shoulder that echoes the Pear’s bilateral outline without generating competing face-up brilliance — their hybrid faceting produces warmth that supports rather than rivals the center stone. Platinum, at 95% purity, resists prong deformation over decades of wear and maintains a neutral cool tone that complements the near-colorless H grade of the center diamond.
