The Diyona fine jewelry buyer's guide
Every piece in this collection is set with lab grown diamonds — chemically and optically identical to mined stones, graded on the same 4Cs, at a fraction of the price. This guide covers the two decisions that shape any jewelry purchase: the metal it's made in, and the piece itself.
Choosing your metal
14k gold — the everyday workhorse
14k is 58.5% pure gold alloyed for hardness. It resists scratching better than 18k, holds polish well, and is the right choice for pieces worn daily — studs, tennis bracelets and stacking bands. Available in yellow, white (rhodium-finished) and rose.
18k gold — richer color, softer metal
18k is 75% pure gold — visibly warmer and more saturated than 14k, particularly in yellow. Slightly softer, so micro-scratches show faster. Choose 18k if color depth matters more than scratch resistance.
Platinum — the heirloom choice
Naturally white, hypoallergenic, ~60% denser than gold. Best for pieces meant to be worn for decades and for sensitive skin.
Finding your piece
Diamond studs
Stud sizes are quoted as total carat weight for the pair — 1 ct tw means a 0.50 ct diamond in each ear. 0.50–1 ct tw reads refined and everyday; 2 ct tw and up is unmistakable across a room. Every Diyona stud ships with secure pushbacks.
Tennis bracelets & necklaces
Total carat weight drives the look: 3–5 ct tw is a delicate everyday line, 10 ct tw and up is a statement piece. Each is set in solid 14k gold with a secure clasp.
Solitaire pendants
A solitaire pendant is the simplest way to wear a serious stone. From 1 ct the diamond reads clearly at conversational distance; 2 ct is a presence.
Bands & anniversary rings
Eternity, half-eternity, five and seven stone — worn alone, stacked, or as a wedding band. Browse the dedicated wedding bands collection for every width and setting style.
Frequently asked questions
Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are chemically and optically identical to mined diamonds. They're graded by the same labs (IGI, GIA) on the same 4Cs and have the same hardness (10 on the Mohs scale).
What size diamond studs should I choose?
Carat weight is quoted per pair, so 1 ct tw is a 0.50 ct stone in each ear. 1 ct tw is our most popular everyday size; 2 ct tw and above is a statement. If you're between sizes, size up — lab grown pricing makes the jump far smaller than it used to be.
How long does Diyona jewelry take to ship?
Most ready-to-ship pieces leave our NYC studio in 5 business days. Made-to-order sizes and metals typically take 7–10 business days. You'll see your specific lead time at checkout.
Do Diyona pieces come with diamond certification?
Every stone above 0.30ct ships with an IGI or GIA grading report. Smaller pavé and melee stones are graded in-house against the same 4C standards.
Can I wear my Diyona jewelry every day?
Yes — 14k gold is built for daily wear. To keep pieces bright, remove them for pools and harsh cleaners, store them separately to avoid scratching, and take advantage of the free re-polish included in our lifetime warranty.
What is your return and warranty policy?
30 days for unworn pieces in original condition (engraving and custom sizes are final sale). All Diyona jewelry carries a lifetime warranty against manufacturing defects, including free re-polish and re-rhodium plating.
