Ethical concerns are now one of the main reasons people choose lab grown diamonds. Buyers want the beauty and permanence of a diamond without the environmental and human cost historically associated with mining. This complete guide explains what lab grown diamonds are, why they are considered a more ethical choice, and how to select one with confidence.
Lab grown diamonds are real diamonds created in a controlled setting rather than mined. They are chemically identical to earth-mined stones, guaranteed conflict-free, use far less land and water, and cost 60–80% less. Browse certified options in our lab grown diamond collection.
What is a lab grown diamond?
A lab grown diamond is genuine carbon crystal grown using one of two methods: High Pressure High Temperature (HPHT), which mimics the conditions deep in the earth, or Chemical Vapor Deposition (CVD), which builds a diamond layer by layer from a carbon-rich gas. Both produce stones with the same hardness, brilliance and fire as mined diamonds. They are not simulants like cubic zirconia or moissanite, and reputable stones are certified by GIA or IGI.
Why lab grown diamonds are an ethical choice
Choosing a lab grown diamond addresses several ethical concerns at once:
- Conflict-free by origin: because the stone's history is fully traceable, there is no risk of funding conflict or exploitative labor
- Lower environmental impact: growing a diamond disturbs no mining sites and typically uses considerably less land and water than extraction
- Transparency: every certified stone comes with documented grading, so you know exactly what you are buying
- Value that does good: paying less for the stone frees budget for a better setting, or simply a more responsible purchase
Are they really identical to mined diamonds?
Yes. Optically, chemically and physically, a lab grown diamond is a diamond. Only specialized laboratory equipment can distinguish the two, which is why independent certification matters. Our diamond education guide explains the 4Cs (cut, color, clarity and carat) that determine a diamond's beauty and price, and these apply to lab grown and mined stones alike.
How to choose the right stone
Start with cut, which has the biggest effect on sparkle, then decide on shape and carat. For most buyers, a color grade of G to I and a clarity grade of VS to SI offers an eye-clean, brilliant stone at excellent value. Always insist on GIA or IGI certification. Whether you are choosing an engagement ring, a pendant or a gift, the same principles apply.
What lab grown diamonds cost
Because they are not constrained by mining, lab grown diamonds typically cost 60–80% less than mined stones of equal grade. In practice, that can mean a 1 carat lab grown solitaire for a price closer to a 0.5 carat mined one. See real comparisons on our natural vs lab grown price comparison.

Do lab grown diamonds hold sentimental value?
Absolutely. A lab grown diamond is a real, lasting diamond. Its meaning comes from what it represents, and many couples feel an ethical choice adds to that significance.
Will a jeweler know it is lab grown?
Not by eye. Lab grown diamonds are identified only through certification and specialized testing, which is why every Rêve Diamonds lab grown stone is independently graded.
