This engagement ring is one of the most beautiful engagement rings in TV history.

The black-centre ring seen on Carrie in the films is widely credited as an Itay Malkin design that entered popular awareness through Patricia Field’s wardrobe for the movies; production notes and designer interviews link the striking black centre and heavy pavé surround to that collaboration. Reported ring specs for the screen piece vary, but many descriptions agree on a roughly five-carat central black stone flanked by dozens of small pavé diamonds set in white gold. These production credits and specific counts have been noted by boutique retailers and costume sources involved with the films.

If you are inspired by Carrie’s black diamond, a few practical verification steps matter. First, distinguish natural black diamonds from treated or composite stones, because natural black diamonds occupy a different market position than enhanced material. Ask for a recognised gemological certificate that states whether the stone is natural or treated and lists weight, cut and any treatments. Second, request full details on pavé total diamond weight and metal type for accurate valuation and insurance purposes. Finally, keep in mind that treatment status and origin information affect value and care. Natural black diamonds in large sizes are uncommon, while many visually similar stones on the market are enhanced; certification is the clearest way to document what you are buying.

When Carrie asks why he chose a black diamond engagement ring, he answers: “because you are not like anybody”. Mr. Big has a great point in this moment. Every woman is unique and deserves a beautiful diamond engagement ring which suits her personality and taste. That is why more men are buying tailor-made rings.

The moment Mr. Big presents the black diamond plays out as one of the franchise’s most quoted lines, when Carrie asks why a black stone and he replies, “because you are not like anybody.” The reveal appears in later storylines and again in the second film, and costume notes and press coverage underline the ring’s memorable screen presence.

These famous engagement rings from Sex and the City not only serve as iconic representations of the characters' journeys through love and commitment but also offer inspiration for those seeking to find or design their own perfect token of affection.

Below are conservative market-value ranges for the main rings featured in the series, followed by the assumptions and reasoning behind each estimate. These ranges reflect what comparable stones and settings would typically command on the open market in recent years.

Carrie Bradshaw - Mr. Big's black diamond ring: $40,000–$80,000

Estimate assumes the centre stone is roughly 4–6 carats, a deep black natural or treated black diamond with moderate clarity typical for darker stones, and a white-gold setting with extensive pavé side stones. The valuation reflects lower per-carat pricing for highly saturated black diamonds versus white stones, while the large size and detailed pavé setting raise the overall value. Uncertainty comes from whether the centre stone is natural or treated, which affects price; the estimate assumes a VS–SI clarity equivalent and a typical per-carat range for sizeable black stones.

Carrie Bradshaw - Aidan’s turquoise ring: $2,000–$10,000

This turquoise-centred ring is valued mainly for the coloured gem and the mounting rather than diamond weight. The range assumes a medium-to-large turquoise cabochon set in gold with modest accent diamonds. Variables include the turquoise’s quality (stabilised or high-quality natural), accent diamond weight, and metal type. Coloured gems vary widely in provenance and treatment, so this estimate is deliberately broad and assumes typical market grades for decorative celebrity pieces.

Charlotte McDougal - Trey’s 2.17 ct solitaire: $25,000–$45,000

Based on the reported 2.17 carat round brilliant and the show's suggestion of a designer purchase, this range assumes a round brilliant around G–H colour and VS–SI clarity equivalent in a platinum or gold setting. The estimate reflects per-carat pricing for well-cut white diamonds of this size plus a modest brand or retailer premium implied by the scene. Uncertainty stems from the diamond’s exact colour and clarity and any designer hallmark.

Charlotte Goldenblatt - Harry’s asscher (reported ~3 ct): $60,000–$140,000

Assuming a high-quality 3 carat asscher-cut diamond with good cut and clarity in a bespoke setting, this range reflects the higher per-carat premium for large step-cut stones. The broad spread accounts for differences in colour and clarity and any bespoke design fees or side-stone weight; an asscher of exceptional clarity and near-colourless grade at this scale can push the value toward the high end.

Miranda Hobbes - cushion-cut with delicate band: $10,000–$35,000

This assumes a centre cushion-cut diamond between about 1.5 and 3 carats, set in a refined band with pavé or channel accents. The range depends on carat weight, cut proportions and clarity; cushion cuts vary in face-up appearance, which strongly influences market value. The assumed clarity is VS–SI equivalent and a white-gold or platinum setting is presumed.

Samantha Jones - diamond flower ring (auction piece): $8,000–$60,000

Because Samantha’s ring is an ornate floral cluster rather than a single large brilliant, value depends on total diamond weight, the centre stone if present, and any designer provenance from the auction. The lower end reflects decorative cluster pieces with modest total carat weight; the upper end accounts for designer pieces or significant centre stones sold through auction houses.

Valuation methodology and assumptions

Each estimate combines visible or reported carat sizes and setting complexity with typical market per-carat ranges for the given cuts and years. When a designer or retailer cue appears in the storyline, a modest brand premium is included. Assumptions above generally follow a conservative continuity: clarity in the VS–SI range, colour near-colourless for white diamonds, and 18k or platinum settings unless otherwise noted. Because the series and promotional material do not provide full gemological reports for the screen pieces, these ranges acknowledge material uncertainty.

Sources and caveats

Estimates draw on reported carat sizes and setting descriptions from publicity material and specialist write-ups, combined with typical retail and auction market behaviour for comparable stones. Exact market value for any screened prop would require a formal gemological report and provenance verification; treated versus natural status for coloured or black stones in particular can change value significantly.
