Moissanite Tennis Necklace Cost: Buyer's Guide
A moissanite tennis necklace typically costs between $390 and $900 for a well-made sterling silver or 18k gold-plated piece, with larger stones and longer lengths pushing past $1,000. That is a fraction of a mined diamond tennis necklace, which can run $5,000 to well over $10,000 for the same iced-out look. The moissanite tennis necklace cost you actually pay comes down to four levers: stone size, necklace length, metal and plating, and craftsmanship. Below we break down each one with real price ranges so you know exactly what you are paying for and where to get the most sparkle for your budget.
What drives moissanite tennis necklace cost?
Unlike a single-stone pendant, a tennis necklace is a continuous line of matched stones, so price scales with how many stones there are and how big each one is. Four factors do most of the work:
Stone size. Tennis necklaces are usually built from 2mm, 2.5mm, 3mm, 4mm, or 6.5mm stones. A 2.5mm line is delicate and affordable; a 4mm or 6.5mm line carries far more total carat weight (measured as DEW, or diamond equivalent weight) and costs proportionally more. At Rokshok, a 2.5mm line starts around $615, while a bolder 6.5mm 18k-gold-plated necklace climbs past $860.
Length. Every extra inch adds more stones. A 15-inch necklace will always cost less than the same design at 22 inches. On our Color Moissanite Tennis Necklace, for example, the price steps up roughly $70 to $110 with each size increase.
Metal and plating. Most affordable tennis necklaces use a .925 sterling silver base. Upgrading to 18k gold, white gold, or rose gold plating adds cost but also warmth and a more luxury finish.
Craftsmanship. Prong-set stones, secure double-lock clasps, and a GRA certificate all signal quality work that holds up to daily wear — and they nudge the price up versus glued or loosely set pieces.
How much is a moissanite tennis necklace at each price tier?
Here is roughly what you get at each budget level, using real Rokshok pricing as a reference point for the moissanite tennis necklace cost across the market.
Entry level — about $150 to $400. Expect smaller 2mm to 3mm stones, shorter 15- to 16-inch lengths, and a rhodium-plated silver finish. Our Round Moissanite Tennis Necklace lands here and still delivers a crisp, classic line for layering.
Mid range — about $400 to $700. This is the sweet spot for most buyers: a 3mm all-moissanite line in a 16- to 18-inch everyday length. The Luxury Moissanite Tennis Necklace and the V-Shape Moissanite Tennis Necklace both sit in this tier and read as far more expensive than they are.
Premium — about $700 to $1,500. Larger 4mm to 6.5mm stones, 18k gold or white gold plating, and longer 20- to 22-inch drops. These pieces deliver maximum presence while still costing a small fraction of a comparable diamond necklace.
Why does moissanite cost so much less than diamond?
Moissanite is lab-grown silicon carbide, created in a controlled setting rather than mined from the earth. Skipping the mining supply chain removes the markup that comes with natural diamonds, which is why you get a diamond-level look without the diamond price. It is also a genuinely high-performing gemstone: with a Mohs hardness of 9.25 it is one of the hardest materials used in jewelry, and its refractive index of 2.65 to 2.69 gives it even more fire and brilliance than a diamond. It is hard enough to scratch glass and bright enough to pass a handheld diamond tester. For shoppers who care about ethics, lab-grown moissanite is also a conflict-free, more sustainable choice.

How to get the best value for your money
A few simple choices keep the moissanite tennis necklace cost down without sacrificing the look:
Choose a 16- to 18-inch length. It flatters the most necklines and uses fewer stones than a long drop, so you pay less while wearing it more. If you are still deciding on fit, our moissanite tennis necklace length guide walks through every size.
Stick with 3mm stones. They are the value sweet spot — substantial enough to sparkle from across a room, small enough to stay comfortable and affordable.
Decide between colorless and near-colorless. Colorless (D-E-F) stones command a slight premium for their icy white look, while near-colorless saves a little and still reads bright in most lighting. Either way, look for VVS clarity for that clean, eye-clean sparkle.
Buy from a seller that includes a GRA certificate and a secure clasp, so the piece you receive matches what was advertised. If you love the iced-out line look on your wrist too, the same logic applies to our moissanite chains.
Is a moissanite tennis necklace worth it?
For most buyers, yes. You get the unmistakable tennis-necklace sparkle, a durable stone that holds up to everyday wear, and an ethical, lab-grown origin — all for hundreds rather than thousands of dollars. The money you save on the stone can go toward a longer length, a gold-plated finish, or a matching bracelet. That is the core appeal of moissanite: diamond-level quality without the diamond markup.
Frequently asked questions
How much is a moissanite tennis necklace?
Most quality moissanite tennis necklaces cost between $390 and $900, depending on stone size, length, and plating. Delicate 2.5mm pieces start lower, while large-stone, gold-plated, or longer necklaces can exceed $1,000 — still far below a comparable diamond necklace.
Are moissanite tennis necklaces real?
Yes. Moissanite is a real gemstone — lab-grown silicon carbide — not an imitation or coating. It is durable (Mohs 9.25), brilliant, and bright enough to pass a handheld diamond tester.
Does a moissanite tennis necklace get cloudy over time?
No. Moissanite does not lose its sparkle or turn cloudy. It can collect skin oils and lotion like any gemstone, but a quick clean with mild soap and warm water restores its brilliance.
How many carats are in a moissanite tennis necklace?
It varies by stone size and length. A 3mm, 16- to 18-inch line typically totals several carats of diamond equivalent weight (DEW), while 4mm and larger lines carry significantly more — which is part of why bigger stones cost more.
