A 20-carat Pear Type IIa diamond pendant of D color and Flawless clarity represents the absolute summit of what the natural world can produce in crystalline carbon — a stone so chemically pure it belongs to a category that accounts for fewer than two percent of all diamonds ever recovered. The Seraphine Drop is offered by Legacy Diamonds & Gemstones as a singular acquisition: a privately presented, fully bespoke pendant commission for the collector who measures significance not in seasons but in centuries.

Every stone presented by Legacy Diamonds & Gemstones is accompanied by full gemological documentation from a recognized international laboratory. independent laboratories certification is available on request. Provenance, conflict-free sourcing documentation, and full chain-of-custody records are presented privately ahead of acquisition. Each Legacy stone is singular; the media and full documentation for your specific diamond are presented privately ahead of acquisition. Legacy operates on a transparency-first model because collectors at this level require it — and because the stone itself, graded at the absolute summit of every category, needs no embellishment.

The chain, the metal, and the design of The Seraphine Drop are fully bespoke — this is a one-of-one commission built entirely around the collector's requirements. Chain length, bail style, prong count, and metal weight are all variables determined in direct consultation with Legacy's design team. No two Legacy pendants at this level are alike, because no two collectors — and no two occasions — are alike. The process begins with a private conversation and ends with an object that could not have been made for anyone else.

  • Carrier: Brink's Global Services — the standard for high-value asset transport
  • Coverage: Fully insured from Legacy's custody to the collector's hands
  • Network: 52-country delivery network; discrete, unmarked, professionally secured
  • Documentation: Full customs and valuation documentation provided at shipment
  • White-Glove Option: In-person delivery and presentation available in select markets; inquire at consultation

A Type IIa diamond of this grade requires no special care beyond the standard protocol for important jewelry: professional cleaning by ultrasonic or steam method with a trusted jeweler, periodic prong inspection — annually at minimum — and storage in an individual padded compartment to prevent contact with other stones or metals. The diamond itself is inert and permanent; the setting, however refined, benefits from the same attentive maintenance any serious collector applies to their most significant pieces.

  • What makes a Type IIa diamond different? Type IIa diamonds contain virtually no nitrogen impurities in their crystal lattice — a condition that occurs in fewer than two percent of all gem diamonds and produces exceptional optical transparency and, often, superior light performance.
  • Can I view the stone before committing? Yes. Legacy presents full media — high-resolution imagery, video, and gemological documentation — privately ahead of any acquisition decision. In-person viewing is arranged in select locations by appointment.
  • Is D Flawless the highest possible grade? Yes. D is the origin point of the the certifying laboratory color scale (colorless), and Flawless is the highest clarity grade — no inclusions or blemishes visible under ten-times magnification. Their combination is the theoretical maximum of the grading system.
  • How long does the bespoke commission take? Timeline is confirmed at consultation and depends on design complexity. Legacy provides a detailed production schedule before work begins.
  • Is financing or a structured acquisition available? Bespoke arrangements are discussed privately. Contact Legacy via WhatsApp or the website to begin that conversation.
The Complete Story

In full — nothing hidden

Most listings hide the writing. We don't — this is the work, in full.

01

About This Piece

Somewhere between one and three billion years ago, deep within the earth's lithospheric mantle, a carbon crystal formed without a single nitrogen atom to interrupt its lattice — a geological accident of almost incomprehensible rarity. That accident is this stone. A 20-carat Pear Type IIa diamond pendant graded D color and Flawless clarity, it represents not merely the top of a grading scale but the outer boundary of what nature is physically capable of producing. Type IIa diamonds, chemically distinguished by the near-total absence of nitrogen impurities, account for fewer than two percent of all gem diamonds; within that fraction, those reaching twenty carats in Pear form with D color and Flawless clarity are encountered perhaps a handful of times in any given decade. The Seraphine Drop is that stone — and it exists on this page because Legacy Diamonds & Gemstones believes the most important diamonds deserve the most considered presentation.

This is a piece conceived as a landmark anniversary gift: an object whose weight, in every sense, is meant to mark a moment that cannot be repeated. Not an occasion for sentiment alone, but for permanence.

02

Overview & Legacy Story

Legacy Diamonds & Gemstones was founded on a single conviction: that the world's most consequential stones should be acquired with the same rigor applied to any serious asset — with full documentation, private presentation, and a process that respects the intelligence of the collector. The Seraphine Drop enters Legacy's care as a stone whose credentials are not aspirational but categorical. D color is not the highest grade on a spectrum; it is the definition of the spectrum's origin point, the standard against which every other white diamond is measured. Flawless clarity means the stone contains no inclusions, no surface blemishes — nothing, under ten-times magnification, to interrupt the crystalline void. These two grades, combined with Type IIa purity and a twenty-carat Pear outline, produce a confluence that serious collectors encounter rarely and acquire even more rarely.

03

Diamond Cut, Color & Clarity

The Pear shape — technically a modified brilliant — unites the spread of a round with the directionality of a marquise, producing a silhouette that elongates naturally against the décolletage while channeling light through fifty-eight or more facets toward a single, pointed terminus. In a stone of this color and clarity, each facet functions as a precision optical instrument: the absence of nitrogen means no yellow undertone absorbs or filters light, and the Flawless clarity means no internal scatter disrupts the path of a ray from entry to exit. The result is a diamond that does not merely sparkle — it refracts, transmits, and returns light with a purity that is measurable as much as it is visible.

  • Carat Weight: Approximately 20 carats (exact weight confirmed at private consultation)
  • Shape & Cut: Pear (modified brilliant)
  • Color Grade: D — the highest color grade on the the certifying laboratory scale; colorless by definition
  • Clarity Grade: Flawless (FL) — no inclusions or blemishes visible under 10× magnification
  • Diamond Type: Type IIa — chemically purest classification; fewer than 2% of gem diamonds qualify
  • Fluorescence: Available on request
  • Polish & Symmetry: Available on request
  • Certification: independent laboratories certification available on request
04

How the Diamond Works on the Neckline

A Pear diamond of approximately twenty carats carries a face-up surface area that commands immediate attention without requiring announcement. Worn as a pendant, the stone's pointed terminus draws the eye downward along the sternum in a vertical line that is architectural in its precision — the neckline becomes a frame, and the diamond its single, irreducible subject. Against bare skin or against the open collar of an evening gown, the effect is the same: the light that enters the crown exits the pavilion and disperses outward in a pattern that shifts with every movement of the wearer, creating a living optical event rather than a static ornament.

05

Carat Weight & Presence at the Throat

Twenty carats in a Pear outline is a stone that occupies real visual territory — its length-to-width ratio, typically between 1.50 and 1.75, means it reads larger than a round of equivalent weight, the elongated form distributing mass across a greater face-up dimension. At the throat, this translates to a presence that is impossible to misread: not ostentatious but emphatic, the kind of emphatic that belongs to a woman who has worn important jewelry before and understands the difference between decoration and declaration. This is a 20-carat Pear Type IIa diamond pendant that announces its own category quietly, through the physics of light rather than the volume of its setting.

06

Pendant Design, Setting & Craftsmanship

The Seraphine Drop is a bespoke commission; no setting exists until the collector's vision is established. Legacy's approach to a stone of this caliber begins with the diamond's own geometry — the Pear's culet, its table dimensions, the precise angle of its shoulders — and builds a mount that serves rather than competes. Platinum is the natural choice at this level: its density secures a stone of this weight without flex, its white tone is optically neutral against a D-color diamond, and its resistance to wear ensures the setting remains structurally sound across generations. Prong placement, bail architecture, and chain integration are all determined in direct consultation, with full CAD visualization provided before a single gram of metal is committed.

07

Personality, Meaning & Emotion

There is a particular kind of anniversary — a twenty-fifth, a fortieth, a fiftieth — that demands a gift commensurate with what has been built. Not jewelry as gesture, but jewelry as record: an object that carries the specific gravity of a life shared, a commitment honored, a history that deserves a physical correlate. The Seraphine Drop was conceived for exactly that moment. Its D Flawless grading is not incidental to this meaning — a stone without color, without flaw, is a stone that encodes an ideal, and the person who receives it understands precisely what is being said without a word being spoken.

08

Investment Value & Future Potential

Among all diamond configurations, the D Flawless Type IIa Pear at twenty carats occupies a position that serious collectors and institutional advisors treat as a discrete asset class. Stones of this specification appear at the highest levels of the international market with genuine scarcity — not manufactured scarcity, but the scarcity of geological accident. Historical patterns across the important-diamond market demonstrate consistent long-term demand at this tier, driven by the finite supply of Type IIa rough and the compounding rarity that results when every grading criterion reaches its theoretical maximum simultaneously. For the collector building a multigenerational portfolio, this is a stone whose significance is unlikely to diminish.

09

How to Wear & Style

The Seraphine Drop is designed for evening, though it tolerates no occasion poorly. Against a strapless column, it becomes the architectural center of an entire silhouette. With a deep V-neckline, it follows the line naturally, the Pear's point leading the eye. For a collector who already owns important colored stones, this pendant functions as the white anchor of a suite — the neutral that makes every other piece in the collection read more intensely by contrast. Chain length is determined at consultation; a longer drop, to the sternum or below, maximizes the elongating geometry of the Pear outline.

10

Who This Is Made For

This stone is made for the collector who does not need to be told what D Flawless means — who already knows, and who is searching not for education but for the right stone at the right moment. It is made for the person marking a milestone that has no adequate commercial correlate, who wants the gift to carry the same permanence as the occasion it commemorates. It is made for the woman who will wear it and the person who presents it: both of them understand that this is not a purchase but a decision, and that decisions of this magnitude deserve a process equal to their weight.

11

Collector Notes & Legacy Perspective

The confluence of Type IIa purity, D color, Flawless clarity, and a twenty-carat Pear outline does not occur by design — it occurs by geological accident, confirmed by human grading, and recognized by a market that has spent decades learning to distinguish the significant from the exceptional. At Legacy, we present this stone without hyperbole because the specification itself is the argument. Collectors who have handled stones at this level understand immediately what they are looking at; those acquiring their first stone of this magnitude will understand just as quickly, because the diamond makes its own case.

12

Red-Carpet & Iconic Style References

  • Elizabeth Taylor wore a 33.19-carat Asscher-cut diamond graded D color as a personal signature — the same D-color standard that defines this stone, demonstrating how the highest color grade becomes inseparable from a collector's identity.
  • Queen Mary, recognized as the most prolific royal collector of important diamonds, built a collection across generations on the same principle that guides this acquisition: that the finest diamonds are chosen not for a season but for a lineage.
