September 2026 edition. Researched by Ansh Gupta at the Jewelry Trade Center, Silom Road, Bangkok.
September 2026
Every trend page tells you what is pretty. This one tells you what women are actually paying for, and separates it from what only looks good on a runway.
Each trend below is marked by how strong the sales evidence is. Updated on the first of every month.
Sales-backed: real purchase data
Emerging: early sales signal
Runway only: editorial buzz, not yet proven in sales

Rings: where the money is going
Rings are the most tracked category in jewelry, so this is where the evidence is strongest. Here is what the numbers say this month.
61%
of engagement ring center stones are lab-grown, per The Knot
26 / 25
round vs oval share of US engagement rings, percent
39%
yellow gold share of US engagement rings
Analyst Edahn Golan puts lab-grown above 50 percent using his own data. Both sources agree it is now the majority.
Sales-backed
Engagement rings
Oval and round, bigger and lab-grown
Round is still number one, but oval is one point behind and closing. The reason is simple: lab-grown pricing lets buyers go up in size. National Jeweler reports completed lab-grown engagement ring sales up 31 percent, with average retail price flat, which means people are buying more stone for the same money, not spending less.
From our side of the bench in Bangkok, this is exactly what we see. The 2 to 3 carat request is now normal, not a stretch.
Sales-backed
Metal
Yellow gold keeps climbing
Yellow gold has become the leading metal for engagement rings. Editors are saying the same for fall: heavier, chunkier, more sculptural bands. If you are choosing one metal for a ring you will wear for decades, this is the safest bet in the data.
Sales-backed
Settings
The plain solitaire is giving ground
In Queensmith’s sales data, the plain solitaire slipped from 47 to 40.3 percent while diamond-set bands rose from 22 to 34 percent. Couples still want a clear center stone. They now want detail around it: pave bands, hidden halos, a second row of sparkle.
Emerging
Shapes and settings
Marquise and bezel are the ones to watch
Marquise is the fastest-growing fancy shape, though it sits around 8 percent of the market. One practical note: the points are exposed, so a protective setting matters. Bezels solve that problem and are getting heavy editorial love, but treat them as a rising trend, not a proven one yet.
Reality check: colored lab-grown diamonds. Designers keep forecasting yellow, pink and blue. Draco’s market report notes that about 98 percent of lab-grown sales are still D color, colorless white. Forecast is not purchase. Colored gemstones such as emerald, ruby and sapphire are a different story and a different category, and we cover those in our education guides.

Earrings, cuffs and collars: the runway list
Outside rings, public sales data is thin. What we can say is what designers, editors and retailers are pushing hard this fall. Treat this section as direction, not proof.
Runway only
Earrings
Big earrings, on purpose
ELLE’s reporting from Fall 2026 shows shoulder-dusting earrings at Valentino, Saint Laurent, Dior, Chanel, Miu Miu, Chloé and Givenchy. The logic is practical too: a tiny stud vanishes next to a chunky knit, a big earring does not. Bombe shapes, oversized tubular hoops and sculptural gold are the ones to look at.
From our side of the bench in Bangkok, this is exactly what we see. The 2 to 3 carat request is now normal, not a stretch.
Runway only
Neck and wrist
One loud piece beats five quiet ones
Retail editors describe fall as the reverse of last year’s delicate stacking: a wide cuff, a chunky collar or an oversized pendant worn alone. Baroque pearls and gold bracelet watches styled as jewelry sit in the same group. One store did report necklace sets at roughly a third of its fall orders, so layering is not dead everywhere. That is a single brand’s data, so we are not ranking it.

Gold at $4,300: what it means for your budget
Gold traded around $4,346 an ounce on September 16, roughly $659 higher than a year ago, according to Fortune. It briefly went past $5,000 earlier this year before pulling back.
Metals Focus expects global gold jewelry demand in 2026 to land more than a third below 2023 by weight, even as retail revenue holds up because each piece costs more.
Put the budget in the stone
A lab-grown center stone gives you size without the price shock, while a thick heavy band is where the gold bill grows. Chunky is the trend, so ask for a hollow or lighter build if you want the look without the weight.
Keep tracking the spread
The Bought List will keep tracking this every month, because gold moves faster than fashion does.
Order before the proposal rush
Roughly 47 percent of couples get engaged between November and February, with December the peak and Christmas Day the single most popular proposal date, according to The Knot.
Made-to-order rings take time to design, approve and set. If you want a custom ring by December, start in early to mid October.
Want one of these, made for you?
Every ring on this page can be made in lab-grown diamond or colored gemstone, IGI or GIA certified where applicable, from our workshop at the Jewelry Trade Center in Bangkok. Tell us the trend and your budget, we will quote you.

How we rank
Most trend articles mix two different things: what customers are buying and what designers hope they will buy. We keep them apart.
Sales-backed means a named study or retailer dataset shows purchases. Emerging means early or small-base sales growth. Runway only means editors and designers are pushing it, but we cannot yet see purchase data.
Questions we get every month
Sales data points to oval and round lab-grown center stones, yellow gold and diamond-set bands over plain solitaires. Runway and editorial coverage points to oversized earrings, sculptural cuffs, chunky collars and mixed-metal stacks.
What are the biggest jewelry trends in September 2026?
Sales data points to oval and round lab-grown center stones, yellow gold and diamond-set bands over plain solitaires. Runway and editorial coverage points to oversized earrings, sculptural cuffs, chunky collars and mixed-metal stacks.
Are lab-grown diamonds the most popular choice for engagement rings in 2026?
Yes, by share. The Knot reports about 61 percent of engagement ring center stones are lab-grown, and industry analyst Edahn Golan puts it above 50 percent.
Is 14k or 18k gold better while gold prices are high?
14k is 58.3 percent gold, costs less and wears harder. 18k is 75 percent, richer in color and pricier. For daily-wear rings, 14k is the practical choice right now.
