A necklace with a single square diamond is one of the easiest pieces to wear every day, and one of the harder ones to choose. Stone shape, metal, setting style, and price all change how it looks and how long it lasts.
This guide uses a real example: the 14 karat white gold necklace with a princess cut drilled diamond from Johann Paul Fine Jewelry in Greenbrae, California. If you are shopping for a princess cut necklace in Marin County, the points below will help you compare options and ask better questions.
A princess cut diamond has a square outline, sharp corners, and a faceted top that reflects a lot of light. Round stones are still the most common choice, but the princess cut is one of the most popular fancy shapes because it looks modern and clean.
It also tends to cost less per carat than a round diamond of similar quality, since more of the rough crystal stays in the finished stone.
In a pendant, the square shape gives a sharp, geometric look that stands out against a round neckline. The corners are the most exposed part of any princess cut, so ask how the design protects them during daily wear.
The piece is listed as the 14 karat white gold necklace with a princess cut drilled diamond, SKU M4-1, in the Johann Paul Collection. The product page lists one princess cut diamond with a total carat weight of 0.40. At the time of writing, the price is $1,625.
A 0.40 carat princess cut measures roughly 4 millimeters per side. That makes it a small, bright accent instead of a large statement stone, which suits everyday wear.
The page offers a special order request instead of an instant checkout. Anyone who wants to buy princess cut necklace in Marin County should send that request and ask the team about timing, since special orders can take longer than pieces already on the shelf. Prices and availability can change, so confirm the details with the store before you decide.
A drilled diamond necklace has a tiny hole through the stone so a chain or wire can pass straight through it. On most drilled designs, the chain holds the stone in place instead of a set of prongs, so very little metal shows around the diamond.
That clean look comes with a few questions worth asking. How is the diamond secured on this chain? Can the chain be replaced or repaired later? What does the store warranty cover? A jeweler can answer these quickly.
Gold karat matters for durability. 14 karat gold is 58.3 percent pure gold mixed with other metals, which makes it harder than 18 karat gold. Many buyers choose 14 karat for pendants that stay on all day.
White gold gets its silver tone from those alloy metals, and many white gold pieces carry a rhodium finish that can wear thin over time. Ask whether this necklace has one and how re-plating works.
Chain length changes how a pendant sits:
16 inches: rests at the base of the neck and shows a small stone clearly.
18 inches: falls just below the collarbone and is the most common length.
20 inches: hangs lower on the chest and layers well with shorter chains.
The product page does not list the chain length, so confirm it with the team before you order.

Regular cleaning keeps a diamond bright.
Soak the necklace in warm water with a few drops of mild dish soap for about 15 minutes.
Brush the back of the stone gently with a soft toothbrush, where oils collect.
Rinse in clean water and dry with a lint-free cloth.
Store it in a soft pouch, away from harder stones that can scratch the gold.
Take the necklace off before swimming or cleaning with chlorine bleach, since harsh chemicals can weaken gold alloys and dull the finish. A yearly check by a jeweler helps catch a worn chain or a loose stone early.
Yes, in many cases. A necklace needs no ring size, which removes the biggest gifting risk with jewelry.
It fits birthdays, anniversaries, graduations, and push gifts. For a wedding, a small diamond pendant works as a gift from the groom to the bride.
Wedding shoppers can also ask about matching earrings or a full set on the bridal designs page. A top wedding jewelry and jewelry set store USA shoppers can visit should be able to match gold color and stone shape across pieces, so the set looks planned instead of mixed.
Set a budget. This necklace is listed at $1,625. If you want a lower price, the Under $1000 collection lists other pieces.
Ask for details that are not on the page, such as chain length, diamond grade, metal finish, and warranty.
