0.43 to 0.74 ct on an identical design: what actually grows
We make this flower in two sizes, and the difference is not what the carat figures suggest. Going from 0.43 to 0.74 ct is a 72% increase in weight. It is not a 72% increase in anything you can see.
Weight is a volume. Width is a length. Scale a shape up in all three dimensions and the weight rises with the cube of the size while the span rises only with the size itself — so a 72% weight increase buys roughly a 20% increase in width. In practice the smaller rosette spans about a centimetre and this one about twelve millimetres. Side by side you see it immediately. Across a table, less than you would expect from the price difference.
What does change out of proportion is presence. Each petal here is a meaningfully larger stone rather than four small ones, so the individual flashes are bigger and slower, and the piece stops reading as a delicate everyday pendant and starts reading as jewellery you chose deliberately. That is the real reason to go up, not the millimetres.
Why this one is SI1–VS2 and the small one is not
The smaller flower is VS1–VS2 throughout. This one runs SI1–VS2, and we would rather explain that than bury it.
At 0.43 ct across four stones, each marquise is small enough that clarity is close to irrelevant — there is not enough table area for an inclusion to find anywhere to sit where it matters. At 0.74 ct each petal has meaningfully more surface, and at that point an SI1 becomes a real grade rather than a formality. SI1 means eye-clean in ordinary conditions for the great majority of stones; it does not mean flawless under a loupe, and on a marquise the place to look is the centre of the table and the two points.
We will send you photographs of these four specific stones under magnification before you buy. On a multi-stone piece that is more useful than any certificate, because no report is issued for stones this size — what you are buying is our selection, and you should be able to check it.
A rosette at the base of the throat
The chain runs 40 to 42 cm, which places a twelve-millimetre ornament just below the hollow of the throat. That is the position where a wide, flat shape works: high enough that the chest is still firm and the flower lies flat rather than tipping, low enough to clear a collar.
Four claws hold each marquise at the girdle, with nothing crossing the table and nothing covering the points. The gallery underneath is open and polished, because a pendant turns and the back of it gets seen.
Specification
Four marquise cut natural diamonds, 0.74 ct total. Colour F, clarity SI1–VS2. 18K white gold, four claws per stone, open polished gallery. Cable chain 40–42 cm. In stock in Antwerp.
The same flower, elsewhere
The 0.43 ct version is the same design in the smaller size, made to order. In warm metal there is the 0.42 ct pendant in 18K yellow gold. For the ear, the 1.51 ct earrings are the largest we make this rosette.
