Questions we get in the store
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 pendant 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. Eleven of the twelve solitaires here say grown, and nearly every other listing names its origin too.
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. More than four pieces in five 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?
Ask before you order. Start on the live chat, or text or ring 212-872-9692; there a person answers from 10 AM ET. Name the piece and the date, and we tell you whether it can reach her in time. A piece made to order takes longer.
Is a chain included with a diamond pendant here?
Only the desk can say for sure, since almost 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, a piece from the case, unworn and unaltered, within fourteen days of delivery, less a five percent restocking fee and our insured label. Custom and name work, and a size made to order for you, are final. Ask the live chat which yours is, or call or text 212-872-9692 by day: a person answers from 10 AM ET.
