Buying lab-grown diamonds for your jewelry

Buying lab-grown diamonds at diamantedelaboratorio.com means accessing a global inventory updated in real-time, with over 700,000 certified gems.

We have worked directly with international suppliers for over twenty-five years: first with mined diamonds, and today also with lab-grown diamonds.

This translates into a transparent purchase. You buy the loose stone, with its IGI or GIA gemological certificate, and then decide what to do with it: set it in a custom piece of jewelry or keep it as a loose diamond.

What is a lab-grown diamond and why buy one

A lab-grown diamond, also called a synthetic diamond, artificial diamond, or cultivated diamond, is a real diamond. It has the same chemical composition, the same hardness on the Mohs scale, the same refractive index, and the same brilliance as a diamond extracted from a mine.

The only difference is its origin: it is created through HPHT or CVD processes under controlled conditions, instead of forming underground for millions of years.

Compared to natural diamonds, cultivated diamonds offer complete traceability, no mining extraction chain, and access to gemological qualities difficult to find in the natural market with equal characteristics.

The 4Cs applied to lab-grown diamonds

Lab-grown diamonds are classified according to the same gemological criteria as natural diamonds, known as the 4Cs:

  • Carat: weight of the diamond.
  • Color: GIA scale from D, colorless, to Z, with yellow hues. D-F grades are the purest; G-H are nearly colorless and common in fine jewelry.
  • Clarity: scale from FL, flawless, to I3. VVS1-VVS2 grades are very pure, and VS1-VS2 have inclusions invisible to the human eye.
  • Cut: quality of the cut, which determines how the diamond reflects light. Very Good or Excellent are the recommended grades.

At Diamante de Laboratorio, we exclusively work with cultivated diamonds of minimum H color, minimum VS2 clarity, and Very Good or higher cut.

1 carat lab-grown diamond: the most common format

The 1 carat lab-grown diamond is the most demanded weight, especially for solitaires and engagement rings.

Within that category, the most common combination for those seeking a balance between presence and gemological quality is D-E color, VVS1-VVS2 clarity, and Excellent or Ideal cut.

Difference between a VVS1 and a VVS2 diamond

VVS1 and VVS2 are two clarity grades within the Very Slightly Included category. Both have very slight inclusions, invisible to the human eye and only appreciable under 10x magnification by a professional.

For fine jewelry, once the diamond is set, the visual difference between VVS1 and VVS2 is indistinguishable, making VVS2 a gemologically sound choice.

How shape influences the diamond

The round brilliant cut is the classic reference and maximizes light return. Fancy shapes, such as oval, princess, emerald, cushion, radiant, heart, marquise, and pear, offer a distinct aesthetic and can provide greater visual presence.

Where to buy lab-grown diamonds with guarantees

Before buying a cultivated diamond, there are five basic points to verify:

  • Official gemological certificate from IGI or GIA.
  • Identifying laser inscription with a unique serial number.
  • Access to the certificate before payment to review the 4Cs.
  • Transparency in the final price, with no hidden charges.
  • Insured shipping with tracking, signature, and end-to-end traceability.

At Diamante De Laboratorio, all diamonds include an IGI or GIA certificate visible before purchase, a laser-engraved identification number, insured shipping, and a guarantee on the diamond's authenticity.

Buying loose diamonds or set in jewelry

Buying loose diamonds allows you to see exactly what you are acquiring: the specific 4Cs of the certificate, the origin of the stone, and its gemological characteristics.

If the final goal is a piece of jewelry, you can buy the diamond with its certificate here and take it to your trusted jeweler, or work directly with The Bright Club, our associated firm specializing in custom design.

FAQs About Buying Lab Grown Diamonds

At Lab-Created Diamond, we offer more than 700,000 lab-created diamonds available in real-time, all certified by IGI or GIA and with a laser-engraved identification number. Each purchase includes prior access to the gemological certificate, insured shipping, and a lifetime guarantee on the diamond's authenticity.

Yes. Buying loose diamonds is the main business model of DiamanteDeLaboratorio.com. You purchase the stone with its IGI or GIA certificate and then decide what to do: keep it, gift it unmounted, or set it in a custom piece of jewelry with our associated brand The Bright Club.

Both grades belong to the Very Very Slightly Included category: they present very very slight inclusions, invisible to the naked eye and only appreciable with 10x magnification and by a professional. VVS1 has fewer and less visible inclusions than VVS2. In a mounted piece, the visual difference between the two is indistinguishable, making VVS2 a gemologically balanced choice.

Yes. Synthetic diamonds, also called lab-grown diamonds, lab-created diamonds, or cultivated diamonds, are real diamonds. They share the same chemical composition (crystallized pure carbon), hardness (10 on the Mohs scale), refractive index, and optical properties as natural diamonds. The only difference is their origin: they are created through HPHT or CVD processes in a lab. Both IGI and GIA certify them as diamonds.

Both laboratories are international references. GIA is the historical reference in gemology and tends to apply conservative criteria; IGI is the leading laboratory in certifying laboratory-grown diamonds, with the same gemological rigor. You can filter the diamonds in the search engine by the type of certificate you prefer. Both include the 4Cs and an identification number laser-engraved on the girdle of the diamond.

No. Their chemical composition is identical to that of a natural diamond, so they retain their brilliance, hardness, and optical properties indefinitely. A certified lab-grown diamond maintains its gemological characteristics throughout its lifespan.
