Are Fiametta’s lab-grown martini studs worth $900?

$3.46 a wear. That is Fiametta's 3-Prong Martini Studs at their $900 entry price, worn once a week for five years — 260 wears — as our calculator runs it. On a stud earring that is a defensible figure, and it is not the number that should decide this purchase.

The number that should is a missing one. Fiametta describes the lab-grown diamonds in these studs as D/E colour and VVS+ clarity, and names no grading laboratory anywhere — not GIA, not IGI, not AGI — so those grades are the brand's own description of its stones rather than a third party's finding. Everything below comes from Fiametta's own catalogue, product and policy pages and from the named publications, as recorded in our brand files on 4–5 September 2026.

What $900 buys

A pair of solid 14k white gold studs — 58.3% gold, the brand works in no other alloy — set with lab-grown diamonds at 1.00 carat total weight. Fiametta states the stones are CVD-grown by suppliers using solar and wind power and holding UN Climate Neutral Now certification. That is the brand's claim, and it is a claim about the supplier, not about the stone in the setting.

Two labelling points, because this catalogue mixes stone types. Every diamond Fiametta sells is lab-grown; the brand offers no natural diamonds at all. The coloured stones are the opposite — natural and mined: known-origin Sri Lankan blue sapphire, emerald, ruby, garnet, spinel, plus antique and heirloom stones. That distinction matters when reading the brand's sustainability language, because its about-page line about no new mining does not cover the sapphires.

The $900 is the starting price for the style. Our file records the studs as also available at 2, 3 and 4 carat total weight, and holds no price for any of them. When the brand cites a Who What Wear piece featuring the 4.00 ctw pair, that is a different earring at a price we cannot state.

Made-to-order runs 6–8 weeks. In-stock pieces ship in 2–5 days, fully insured, signature required, to the US and Canada only.

What it costs, in context

$900 sits near the floor of this catalogue. The core range runs $440 to $7,600, with most pieces between $900 and $5,600, and the studs are the entry point into the diamond side of it. Above them: Mini Link Huggies at $2,200, the Classic Tennis Bracelet from $2,300, the Emerald Solitaire Signet Ring at $4,800 in an emerald-cut lab-grown diamond, the same ring at $5,600 in a natural Sri Lankan sapphire, the Double Link Earrings at $6,800 in 1.68 ctw lab-grown diamonds, a $7,600 Jumbo Bezel Pavé Pendant and a $10,400 Emerald Bezel Tennis Bracelet. Statement link necklaces are listed at $38,900 to $47,400.

The metal is constant at 14k across all of it, so everything you pay above the entry point is stone size, stone type and setting labour.

Third-party pricing exists. Moda Operandi lists 53 Fiametta pieces at $440 to $5,600, and Broken English carries 33 online, so the brand's own prices are not an isolated quote. JCK, in verified coverage by Karen Dybis, records a 1.14 ct natural sapphire Pride pendant at $7,740, and Air Mail records the numbered Pride charms from $4,920 — both outside prices consistent with the brand's own.

The terms, before any recommendation

Seven days. Returns must be requested within seven days of receipt — among the fifteen brands we cover only Noblemars, at five days, is tighter, and there fourteen days is the norm and thirty the rare exception. Return shipping is deducted from the refund and the original shipping is not refunded at all, so a change of mind costs freight in both directions.

Three traps sit under that. All custom work — engraving, a different gold colour, a special-order size — is final sale. Canadian orders cannot be returned at all, on a brand that ships only to the US and Canada. And a made-to-order pair takes 6–8 weeks to arrive, after which the clock is seven days.

Repair coverage runs one year for material and workmanship defects; wear-and-tear repairs take 4–6 weeks and sit outside it. The brand's "100% waterproof" line is its own claim, published alongside advice to avoid chlorine and cleaning chemicals, and we found no third-party consumer review record for this brand anywhere — no Trustpilot profile, no BBB listing, nothing on Sitejabber or Thingtesting.

Against Vrai and Ring Concierge

Fiametta's own comparable set is Vrai, Kimai, Ring Concierge, Jade Trau and Dorsey. We hold no sourced price from Vrai or Ring Concierge for a 1.00 ctw lab-grown stud in 14k, and we will not guess at one. What follows is the structure of that comparison, not its result.

A like-for-like comparison on lab-grown studs needs five things matched: carat total weight, karat and colour of the metal, the cut and setting, the colour and clarity of the stones — and the authority behind those grades. Fiametta supplies the first four in public. On the fifth it supplies a self-description, D/E VVS+, with no laboratory named. That is the gap that makes a price comparison impossible before any competitor's number is even needed: a stud sold as D/E VVS+ on a named IGI or GIA report and a stud sold as D/E VVS+ on the seller's own say-so are not the same product, and any price difference between them is unreadable until the reports are.

The second structural point is resale, and it runs against every lab-grown purchase equally. Lab-grown diamonds carry little resale value, and no secondary-market data exists for this brand at all. So the resale field on our calculator stays at zero here — not as caution, but because there is nothing to enter.

The arithmetic

Studs are the one fine-jewelry category where a high wear count is not a fantasy. At 260 wears the entry pair is $3.46. Worn three days a week for a decade — 1,560 wears — it is $0.58 a wear, which clears the Buy-at-full-price band with room to spare.

The reverse case is instructive. Bought as occasion jewelry and worn four times a year for five years, the same $900 is $45.00 a wear — a Skip. Nothing about the earring changed. The wear count is the whole argument, which is why it should be your count and not the seller's.

THE PENNYWEIGHT VERDICT

Buy at full price — if you will wear them most days, and only after you have asked for the grading report.

The number is $0.58 a wear at 1,560 wears. Studs earn that count more easily than anything else in a jewelry box, and at 14k solid gold with a stated 1.00 ctw the piece is what it says it is on metal and weight. The exposure is not the price; it is the seven-day window on a 6–8 week make, with custom orders final sale and Canadian orders not returnable at all.

Before you buy, ask Fiametta which laboratory graded the stones and ask for the report. If the answer is that the grades are in-house, the $900 is still $0.58 a wear — but you are paying it on the brand's description of the stones, and you should know that going in. Our full read on the label is in the Fiametta profile.
