What Is the Best Quality Moissanite: Identifying Top-Grade Gems

Short answer: The best quality moissanite is colorless (D–F), has high clarity (VVS or better), and has an excellent cut that maximizes brilliance and fire. Buy it from a seller who provides a grading certificate and clearly discloses what you are getting.

Not all moissanite is the same. Two stones of the same size can look very different on the hand: one bright, white and full of fire, the other slightly tinted, glassy or dark in the center. The difference comes down to color, clarity and above all cut, plus the quality of the setting it sits in. This guide explains how moissanite is graded, what "top grade" really means, how to check a stone yourself, and which warning signs to watch for when you shop.

What Moissanite Is

Moissanite is silicon carbide, a gemstone first discovered in 1893 in a meteorite crater. Natural moissanite is extremely rare, so all moissanite used in jewelry today is lab-created. It is the second hardest jewelry gemstone after diamond (9.25 on the Mohs scale) and has more fire than diamond, which gives it its famous rainbow sparkle.

Moissanite is not a diamond and should never be sold as one. It is its own gemstone, and its quality is judged on its own terms, even though the grading language borrows from diamond's 4Cs.

How to Judge Moissanite Quality

Moissanite quality is described with the same four factors used for diamonds: color, clarity, cut and size. Because moissanite is grown in a lab, the range of quality is narrower than with mined stones, but the differences still matter.

Color

Moissanite is graded on a scale similar to diamonds. D–F is colorless and the premium choice; G–I is near-colorless and can show a faint warm tint, especially in larger stones. For white gold or silver settings, choose D–F.

Early moissanite often had a noticeable yellow or green tint. Modern growing methods produce truly colorless material, which is why D–F is now the standard for top-grade stones. Near-colorless G–I stones are not "bad"; their slight warmth can look lovely in yellow or rose gold and often costs a little less.

Clarity

Top-grade moissanite is VVS1 or VVS2, meaning any inclusions are very difficult to see even under 10x magnification. VS stones can still look clean to the eye, but VVS is the standard for the best quality.

Typical inclusions in moissanite are tiny needle-like growth marks or pinpoints formed as the crystal grows. In a VVS stone you would need a loupe and a trained eye to find them. What matters most for everyday wear is that the stone is "eye clean": nothing visible from a normal viewing distance.

Cut

Cut quality decides how much the stone sparkles. A well-cut moissanite has symmetrical facets and good proportions that return light evenly. Poorly cut stones look glassy or show dark areas.

Cut is the factor that separates good moissanite from great moissanite. Because moissanite bends light so strongly, small errors in angles show up as windows (a see-through area in the center) or extinction (dark patches). A precisely cut stone looks bright from edge to edge and shows balanced flashes of white and color. Cutters also orient the stone so its double refraction is hard to see through the top.

Polish and Symmetry

Two finer details complete the picture. Polish describes how smooth the facet surfaces are: a well-polished stone has crisp, glassy reflections with no fuzzy or scratched-looking facets. Symmetry describes how evenly the facets meet and how centered the table and culet are. Good polish and symmetry are what make a stone's sparkle look sharp and orderly rather than scattered.

Size

Moissanite is lighter than diamond, so it is usually sold by millimeter size or "diamond equivalent weight" (DEW). Compare stones by mm size, not just carat.

Moissanite Quality Grades Compared

This table summarizes how quality levels typically compare, so you can decide where to spend your budget:

Tip: If you must compromise, keep cut at the top of your list. A beautifully cut G color stone usually looks better on the hand than a poorly cut D color stone.

Choosing the Right Grade for Each Piece

The "best" moissanite depends partly on how it will be worn. A center stone in an engagement ring is studied closely every day, while tiny accent stones in a band are seen as a group. Use this as a guide:

For matched sets, consistency is more important than the absolute grade. A tennis bracelet where every stone is the same color and brightness looks far better than one that mixes grades, even if a few of the stones are technically higher.

Shapes and How They Affect Quality

Shape changes how color and cut quality show, so it is worth choosing the grade with the shape in mind.

• Round brilliant: the most forgiving shape. Its facet pattern hides faint color well and gives the most even sparkle. Browse round moissanite for classic designs.
• Oval, pear and marquise: elongated shapes can show a "bow tie", a darker band across the center. A good cut keeps it small. Our oval moissanite range shows this shape well.
• Cushion and radiant: mixed cuts with lots of fire. Larger ones can show a hint of warmth at the corners, so D–F is a safe choice.
• Emerald and Asscher: step cuts with long, open facets that show clarity and color most clearly. Choose VVS clarity and D–F color for these shapes.

Size and Visible Color

The bigger the stone, the easier it is to see any tint. In small accent stones, G–I color is rarely noticeable. In a center stone of about 8 mm or more, many buyers prefer D–F so the stone looks crisp white from every angle.

Fancy Colored Moissanite

Moissanite is also made in deliberate colors such as blue, green, pink, yellow and black. For these stones, the color grading scale above does not apply in the same way. Instead, look for an even, saturated color with no patchy zones, plus the same clarity and cut standards as colorless stones. A well-cut colored moissanite keeps the strong fire that makes the gem special.

Certificates

Quality moissanite usually comes with a certificate, such as a GRA report, stating its color, clarity and size. A certificate confirms the stone is moissanite and documents its grades, but it is the seller's honesty and craftsmanship that matter most — always buy from a jeweler who discloses the stone type clearly.

Moissanite certificates are not the same as the independent laboratory reports used for diamonds. Lab grown diamonds are graded by labs such as IGI and GIA, which assess each stone individually in detail. Treat a moissanite certificate as useful documentation, and judge the stone itself by looking at it, ideally in photos and video under different lighting.

How to Inspect a Moissanite Yourself

You do not need to be a gemologist to spot a good stone. Use these simple checks when the piece arrives or when you view it in person or on a video call:

1. Face-up brightness: look straight down at the stone. It should be bright across the whole surface, with no dull or see-through center.
2. Color against white: place the piece on a sheet of white paper and look from the side. A D–F stone looks icy white; a warmer grade shows a faint yellow tone.
3. Eye clean: at arm's length and at reading distance, you should not see any spots or lines.
4. Symmetry: the outline should be even, and the facet pattern should look balanced, not lopsided.
5. Daylight and lamp light: in sunlight you should see lively rainbow flashes; under indoor lamps, crisp white and colored sparkle.
6. Setting check: the stone should sit straight and secure, with no movement when you gently press it.

Questions to Ask the Seller

• Grades: what are the exact color and clarity grades of this stone?
• Size: what is the measurement in millimeters?
• Metal: is the setting solid gold or 925 sterling silver, and what karat?
• Returns: what happens if the stone does not look as expected?

Setting and Metal Quality

Even the best stone looks ordinary in a poorly made setting. When judging a moissanite piece, look at the metal work as closely as the stone:

• Solid precious metal: Ivevar sets moissanite in 10K, 14K and 18K gold and in 925 sterling silver. Check the stamp and the written description.
• Clean prongs: prongs should be evenly shaped, smooth and tight over the stone, without sharp tips.
• Even finish: polished surfaces should be bright and free of tool marks; inside edges should be smooth.
• Matched side stones: in halo, pavé and eternity designs, small stones should match the center in color and brightness.

For pieces you will wear every day, such as an engagement ring, 14K gold balances durability and color well. Explore our moissanite engagement rings to see high-grade stones in a range of settings.

Buying Top-Grade Moissanite Online

Most moissanite is now bought online, and you can judge quality well from a distance if the seller gives you enough information:

• Full specifications: color grade, clarity grade, shape, mm size and metal for every piece.
• Real photos and video: look for footage in daylight as well as studio light, so you can see true color and sparkle.
• Live viewing: a virtual appointment lets you see the actual stone move under light and ask questions in real time.
• Returns window: a clear returns policy, such as Ivevar's 30-day easy returns, lets you check the stone at home.
• Custom options: if you want a particular size or shape, a seller that offers custom jewelry can source a stone to your grade.

Durability and Care

Because moissanite is so hard, it resists scratches and keeps its polish through daily wear. Clean it in warm water with mild dish soap and a soft brush, rinse, and dry with a lint-free cloth. Quality moissanite does not go cloudy or change color over time; dullness is almost always just surface buildup.

• Weekly: a quick soak and brush, especially under the stone where lotion collects.
• Storage: keep pieces in separate soft pouches so harder stones do not scratch softer metal.
• Yearly: have a jeweler check prongs and settings, particularly on rings.
• Avoid: chlorine and harsh cleaning chemicals, which can harm the metal.

How Top-Grade Moissanite Ages

Because it is so hard, a well-cut moissanite keeps sharp facet edges for many years. What changes over time is usually the setting: prongs wear thin and polish softens. Looking after the metal is the key to keeping a top-grade stone looking new.

Ethics and Value

Lab-created moissanite involves no mining, which makes it a conflict-free and lower-impact choice. It typically costs a small fraction of a diamond of the same size, so you can choose a larger stone or a solid gold setting for the same budget.

Within moissanite itself, the jump from good to top grade is usually modest compared with the price differences between diamond grades. That is why many buyers choose D–F, VVS and an excellent cut as standard: the extra cost is small, and the stone will look its best for life. If you would rather have a real diamond, a lab grown diamond engagement ring offers diamond hardness and IGI certification on many stones.

Where Your Money Goes

In a finished piece of moissanite jewelry, the stone is only part of the price. The metal and karat, the weight of the setting, the number of side stones and the hours of hand finishing all add up. That is why two rings with similar center stones can be priced differently, and why a well-made setting is worth paying for.

Red Flags When Buying Moissanite

• Misleading names: "moissanite", "diamond simulant" without the word moissanite, or listings that call it a diamond.
• Grades with no detail: "AAA quality" or "top grade" without color, clarity and size stated.
• Carat only: no millimeter size, which makes it hard to compare stones.
• Filtered photos only: no real photos or video in natural light.
• Unclear metal: plated base metal described vaguely as "gold".
• No returns: a seller confident in their stones should let you return them.

At Ivevar, every piece is described with its stone and metal clearly stated. We set top-grade moissanite in 10K, 14K and 18K gold and 925 sterling silver, ship worldwide with free shipping, and offer 30-day easy returns so you can see the quality for yourself.

Frequently Asked Questions

What grade of moissanite is the best?

D–F color, VVS clarity and an excellent cut represent the highest quality moissanite.

Does high-quality moissanite look like a diamond?

At a glance, yes. Up close, moissanite shows more rainbow fire, while diamond shows crisper white sparkle.

Will moissanite get cloudy?

No. Quality moissanite stays clear for life. If it looks dull, a simple cleaning restores its sparkle.

Is G–I moissanite worth buying?

Yes, especially in yellow or rose gold settings and in smaller stones, where the faint warmth is hard to see.

Is VS clarity good enough?

A VS moissanite that is eye clean will look clean when worn. VVS is the standard for top grade and gives extra peace of mind in step cuts.

Why is cut so important for moissanite?

Moissanite bends light very strongly, so precise angles are needed to return that light evenly. A poor cut shows dark or see-through areas.

Does moissanite change color over time?

Modern colorless moissanite keeps its color. Any yellow look is usually dirt or lotion on the back of the stone.

Should I choose moissanite or lab grown diamond?

Choose moissanite for maximum sparkle at a lower price; choose lab grown diamond if you want a real diamond with the highest hardness.

How can I tell if my moissanite is good quality without a certificate?

Check that it looks bright across the whole face, white against paper, clean to the eye and evenly cut, and ask the seller for written grades.
