A 2.5 mm tennis necklace at 18 inches lands at the collarbone. Weights at this width vary by build; read the grams on the listing. 48 of the 171 necklaces here come in 18 inches.

Questions we get at the counter
Which diamond necklace should I buy her as a gift?
A diamond heart in 14K gold is the safe gift. Hearts sold more than any other shape, with a pink sapphire heart first among them. If she likes one stone on its own, a lab-grown solitaire is the other sure choice.
What length should a diamond necklace be?
Eighteen inches suits most women, with the pendant resting on the collarbone, and it is the length most pendants here print. Some say 16, which sits higher, close to the throat. Read the length on each listing, and ask us when you want it longer.
Are lab-grown diamond necklaces real diamonds?
Yes. A lab-grown diamond is the same hard carbon crystal as a mined one, and neither your eye nor a loupe can tell the two apart. All but two solitaires here say grown, and most other listings do not say, so ask us.
More questions we get
How many carats should a diamond necklace be?
Near one carat for a solitaire that shows on a fine chain, the size of the solitaire bought most here. On a heart or a cross the carats are spread over many small stones, so judge the look rather than the number.
Is 14K or 18K gold better for a diamond necklace?
14K is better for a necklace worn every day, since the harder gold keeps prongs tight. Three pieces in four are 14K. 18K has the richer color and a softer surface, and its baguette hearts sold well.
Will a diamond necklace get to her in time for a gift?
Often, if the necklace says In stock by its price, since those usually ship in two to five business days. Anything made to order takes longer. Text the desk first when the gift has a date, or note it at checkout.
Is a chain included with a diamond pendant here?
Only the desk can say for sure, since no listing spells out what ships in the box. Titles that read pendant alone are the ones to ask about. Tell us the length you want, and we say whether a chain comes with it.
Can I return a diamond necklace?
Yes, unworn and unaltered, if you reach the desk at 212-872-9692 within fourteen calendar days of delivery. It travels back on our insured label, and a five percent restocking fee plus that label come off the refund. A name made for her is final.
