This collection covers natural loose diamonds in every style: classic round
brilliants, fancy shapes like oval, pear, princess, emerald, cushion and marquise, plus distinctive options such as rose cut, salt and pepper, and pink and fancy-color diamonds, along with small accent stones, baguettes and briolettes. Whatever your design calls for, you can source the exact stone loose. Browse all loose diamonds. -
The round brilliant cut sparkles the most. Its 57 to 58 precisely arranged facets are engineered to return the maximum amount of light, which is also why it is the most popular shape. Princess, radiant, cushion and oval cuts follow closely and offer beautiful brilliance with a different look. Whatever the shape, a high cut grade matters more for sparkle than the shape itself.
-
Start with the look you love, then weigh practical points: elongated shapes like oval,
marquise and pear tend to look larger than a round of the same carat weight and flatter the finger, while step cuts like emerald and Asscher show a clean, glassy elegance rather than intense fire. Your setting matters too. Tell us the style and budget and we will help you match shape to stone. -
This collection is natural, earth-mined loose diamonds. If you prefer a lab grown stone identical in look but lower in price we keep those in a separate collection. Shop labgrown diamonds.
-
Yes. Diamonds can be supplied with independent grading reports from labs such as GIA or IGI confirming the 4Cs and origin. The certificate is your proof of quality and authenticity. If you need a specific certification on a stone, mention it when you enquire.
-
Cut first it drives the sparkle and can make a stone look livelier than a higher grade with a poor cut. For color, a near-colorless grade (around G to J) looks white once set but costs less than colorless. For clarity, an eye-clean stone (often VS or a well-chosen SI) looks flawless to the eye without paying for perfection you cannot see. Carat is the weight, and a touch under a round number stretches the budget.
-
Yes. We supply MM-size accent stones, baguettes and melee, ideal for pavé, halos, side stones and repairs, in single stones or matched parcels. See accent and baguette diamonds, or start a wholesale enquiry for bulk pricing.
-
Absolutely that is the main reason to buy loose. You choose the exact stone, then have it set by your own jeweler into an engagement ring, pendant, or any custom piece. If you need a specific shape, size or matched pair that is not listed, we also offer custom sourcing.
-
Yes. Salt and pepper diamonds are natural stones with speckled black-and-white inclusions and a one-of-a-kind look, and we also carry pink and other fancy-color diamonds for standout designs. Salt and pepper diamonds and pink diamonds are available loose.
-
We serve customers across the USA with free standard shipping and returns, and every stone is packaged securely and shipped with tracking. If a stone is not right,
you can return it under our returns policy just reach out and our team will
help. -
The collection spans a wide range of loose natural gemstones in many forms: faceted stones and cabochons, briolette beads, rondelles, ovals and rounds, tumbles, carvings and charms, plus raw gems and pearls. That makes it suited to fine jewelry,
beading, and one-of-a-kind designer work alike. Browse loose gemstones. -
We sell natural gemstones and disclose any treatment clearly. Many colored stones are
routinely enhanced gentle heat to deepen color, for example which is normal and accepted as long as it is disclosed, and we tell you up front. We do not pass off treated or lab-created stones as untreated natural ones, so you always know what you are buying. -
Genuine stones show natural inclusions, a consistent hardness, and a refractive index a gemologist can measure, while imitations are often suspiciously flawless, glassy, or contain tiny gas bubbles. For higher-value stones, an independent report from a lab such as GIA or IGI confirms identity, treatment and quality. Ask us for documentation on any stone where it matters.
-
A faceted gemstone has flat cut faces that maximize sparkle; a cabochon is polished into a smooth, rounded dome with no facets, which suits opaque and star stones beautifully; and a briolette is a teardrop shape faceted all around, usually drilled as a bead for earrings and pendants. See cabochons and faceted gems or briolette
beads. -
Hardness varies a lot. Sapphires and rubies are very hard and hold up to daily wear, while softer stones such as opal, pearl, emerald and turquoise scratch or chip more easily and are better in earrings, pendants, or occasional-wear pieces. For a colored stone in an everyday ring, choose a harder gem and a protective setting — we are glad to advise based on your design.
-
“Precious” traditionally means diamond, ruby, sapphire and emerald, while everything else amethyst, topaz, garnet, aquamarine, tourmaline and so on is called semi-precious. The labels are more historical than scientific; many semi-precious stones are rare and valuable. What matters most is the individual stone's color, clarity, cut and carat.
-
Yes. Beyond single stones, we supply briolette and bead strands, rondelles and matched parcels for designers and makers, with wholesale pricing for trade quantities. Start a wholesale enquiry.
-
Yes. Uncut gemstones skip the labor of cutting and polishing, so they cost less and appeal to collectors, faceters, and designers who want an organic, natural look or plan to cut the rough themselves. They are less uniform than finished stones but full of character. Browse raw gems and pearls.
-
For most stones, warm water with a little mild soap and a soft brush is enough; rinse and dry with a soft cloth. Softer or porous stones like opal, pearl and turquoise need gentler care, so avoid harsh chemicals and ultrasonic cleaners. Store stones separately so harder gems do not scratch softer ones.
-
Yes. If the exact stone, shade, shape or matched pair you need is not listed, we offer custom sourcing share your requirements and our team will hunt down options for you.
-
Yes. A lab grown diamond is chemically, physically and optically identical to a mined
diamond the same crystallized carbon, grown in a controlled environment instead of underground. The U.S. Federal Trade Commission recognizes them as real diamonds, and they pass a standard diamond tester. The only real difference is origin. Shop lab grown diamonds. -
Visually and structurally they are the same, and only specialized lab equipment can tell them apart. The differences are origin, price and rarity: lab grown stones cost much less for the same size and quality, while natural diamonds are finite and carry a traditional rarity premium. Both are graded on the same 4Cs.
-
They can be produced in weeks rather than forming over billions of years, and supply is not limited by mining. As the technology has improved, prices have fallen sharply, so a lab grown stone today typically costs a large fraction less than a comparable natural diamond which lets you choose a bigger or higher-quality stone for the same budget.
-
For most buyers, VS1 to VS2 is the sweet spot: eye-clean and brilliant without paying for perfection you cannot see. Step the clarity up toward VVS for larger stones (roughly 1.5 carats and up) or for step cuts like emerald and Asscher, where the open facets make inclusions easier to spot. You can filter this collection by VS1, VS2, VVS1 and VVS2 to compare.
-
D to F is colorless and the most premium; G to J is near-colorless and usually the best value, looking white once set. If you are going above 1 carat, a G or H grade helps keep the stone looking bright. Warmer metals like yellow or rose gold also make any faint tint less noticeable.
-
Carat is weight, not size, but as a guide a 1 carat round brilliant measures about 6.4 to 6.5 mm across the top and a 2 carat round about 8 to 8.1 mm. Elongated shapes such as oval, pear and marquise tend to look larger than a round of the same weight. Because lab grown costs less per carat, many buyers size up for the same budget. You can filter this collection by carat range to narrow your search.
-
Yes. Lab grown stones are graded by the same independent labs as natural diamonds, most commonly IGI or GIA, with a report covering cut, color, clarity and carat and confirming the stone is laboratory grown. Always keep the certificate with your purchase.
-
Generally less than natural diamonds. Because new lab grown stones keep getting cheaper to produce, resale tends to be a modest share of the original price, while natural diamonds hold value somewhat better. If you are buying a stone to keep and wear, resale is largely academic; if long-term resale is a priority, a natural diamond may suit better.
-
Yes. A lab grown diamond has the same hardness as a mined one a 10 on the Mohs scale, the hardest of any gem so it resists scratching and is built for daily wear. It will not fade, cloud or wear out over time. In everyday terms, it lasts just like any diamond.
-
Yes. You can filter this collection by shape, carat range and clarity to find an exact
match, then have the loose stone set by your own jeweler into any design. If
the precise combination you want is not listed, our custom sourcing team can
find it. Browse lab grown diamonds.
