Gold Karat Guide
A clean, low-profile pair for every day: 0.7 carat total weight that the pair meets or exceeds (about 0.35 ct per ear — matched stones may vary slightly, one under / one over half), graded VVS clarity and E–F colour with an Excellent cut. Lab-grown diamonds are real diamonds — same hardness, fire, and brilliance as mined stones — chosen here for quality you can wear without ceremony.
The martini setting is three slender prongs that taper under the stone, holding it close to the ear. Less metal around the girdle means more light through the diamond, and the low cone keeps the pair comfortable for long wear. In photos, the silhouette reads sharp and modern against the lobe.
Each pair is made to order in our Hamilton, Ontario workshop — typically ready in about two weeks — in 10k, 14k or 18k yellow, white or rose gold, or platinum. Push backs (our custom Rudix butterflies) are the safer everyday recommendation — sturdier and more durable for daily wear; screw backs remain available if you prefer them. Every diamond ships with its own IGI certificate, and the finished pair includes a certified appraisal. We ship within Canada and the United States.

Honest answers to what customers ask us most before choosing lab-grown diamond stud earrings. Yes. A lab-grown diamond is carbon crystallised into diamond — the same hardness (10 on the Mohs scale), the same fire, the same brilliance as a mined stone. It is not moissanite and not cubic zirconia; a jeweller's loupe cannot tell it from a mined diamond, because chemically and optically it is one. The only difference is origin: grown in a controlled facility over weeks instead of mined from the earth — which is also why it costs less and carries no mining footprint. Every stone, individually. Each diamond in your pair comes with its own IGI certificate verifying its carat weight, colour, clarity and cut — two stones, two certificates, independently graded. On top of that, the finished pair comes with a certified appraisal document for your insurance records. You can verify each IGI report number directly on IGI's website. Our studs are set with VVS clarity, E–F colour, Excellent cut round lab-grown diamonds. In plain terms: We deliberately don't set lower-colour or lower-clarity stones in studs — earrings sit in daylight next to the face, where quality shows. Carat weights are the total for the pair that the pair meets or exceeds — each ear is about half; matched stones may vary slightly (one under / one over half). The number that matters visually is the diameter of each stone: If you're between sizes, visit our Hamilton showroom and try them against your ear — five minutes settles it better than any chart. Both are included at no extra cost — you choose when ordering. Every pair is made to order in your choice of 10k, 14k or 18k gold — yellow, white or rose — or platinum. All ten options are standard; pick yours from the selector above. On white gold: its bright silvery finish comes from a thin rhodium plating, standard across the industry, which can be refreshed over the years. Platinum is naturally white all the way through. Growing a diamond above ground costs far less than mining one out of it — no exploration, no extraction, no long rough-trading chain. That saving is real and it lands in the price: the same size, colour and clarity typically costs a fraction of its mined equivalent. Nothing about the stone itself is lesser. The certificates grade lab-grown diamonds on exactly the same 4Cs scale (cut, colour, clarity, carat) as mined ones. Each pair is made to order in our Hamilton, Ontario workshop — please allow up to 2 weeks for crafting, inspection and your certificates and appraisal, then standard shipping time on top. Shipping is free, tracked and insured across Canada and the US. Need them for a specific date? Contact us before ordering and we'll tell you honestly whether it's achievable. Daily wear is exactly what studs are for. Diamond is the hardest natural material there is; the stones will outlast all of us. And once a year, bring them in: your 3-Year Extended Care includes a free professional polish and clean plus a prong tightening and stone-security check. Yes — you have 30 days from delivery to return or exchange, provided the earrings are unworn and in original condition with their certificates, appraisal and packaging.

What makes Rudix different from big online diamond sellers?
Anyone can sell you a diamond online. Here's what only a real jeweller can offer. Rudix Jewellery is a bricks-and-mortar shop at 1595 Upper James Street, Hamilton, Ontario — not a warehouse or a dropshipper. See the studs in person, try sizes against your ear, or call and speak to the owner. If anything ever needs attention, there's a door to walk through. Your pair is crafted to order in our own workshop — and before it's set, we pair the two IGI-certified stones ourselves so they match for colour, cut and life on the ear. Mass sellers pull two stones from a bin; we build you a matched pair. Each diamond carries its own independent IGI certificate, and the finished pair leaves with a certified appraisal for your insurance. You can verify every report number on IGI's own site — you never have to take our word for what you bought. Our settings are custom-made — substantial metal made to last and stay timeless — not thin conventional factory settings. The bench that builds them is the same bench that stands behind them. Every pair includes our 3-Year Extended Care: a free professional polish and clean once a year, a prong tightening and stone-security check, and one repair of accidental damage per year. The bench that made your earrings is the bench that looks after them. Not sure between 1 and 1.5 carats, or which backs to choose? (We usually recommend push backs for everyday.) Ask us — we'll tell you what we'd choose and why, even when the honest answer is the less expensive one. Our best advertising is how the earrings look on you, not the invoice.Why Buy Your Studs From Rudix
