Are lab diamond necklaces real diamonds?
Yes, and the distinction matters when you shop. Each stone is crystallized carbon, exactly what miners dig from the ground, rated 10 on the Mohs scale. A simulant only imitates a diamond and is a different material altogether. You will see these stones called lab grown, lab created or simply lab diamonds; all three mean a real diamond that was grown rather than mined.
Because the material is identical, the usual rules for judging sparkle still apply. Cut drives brilliance, color runs from D (colorless) toward Z, and clarity describes how clean the stone is inside.
Where the savings show up around your neck
Since lab created diamonds cost far less than natural ones of the same size and grade, the real question is how you want to spend the difference. There are three common answers: a larger center stone on a solitaire, a fuller line on a tennis necklace, or a whiter, better cut stone at the size you already had in mind.
Which one makes sense depends on the piece. On a single pendant, size is what people notice first, and a near colorless stone (G to J) looks bright on a chain. On a line of many diamonds, close matching from stone to stone does more for the look than any one diamond.
Resale and what you are paying for
Lab grown diamonds have low resale value, while a natural diamond holds its value better. Be honest with yourself about that before you buy. If the necklace is something to wear and enjoy, a grown stone gives you more diamond on the day you put it on. If you think of jewelry partly as something to pass on with lasting value, a natural stone may be worth the higher cost.
Rare Carat sells direct and is the merchant of record on every order, so the company you pay is the company that stands behind the piece.
Matching the style to how you will wear it
Let your daily habits pick the style. A single stone on a chain is the everyday choice; browse lab grown diamond pendants for that look. A full line is the event piece, and the lower cost of lab stones is often what makes diamond tennis necklaces realistic.
