Our verdict
Suits a buyer who wants an 18K solitaire necklace and cares about the diamond cut, with color F or better and clarity VS2 or better stated. Look elsewhere if you want a stone above 1ct, a stated gold color, or a clear statement of when an IGI report is included. The main caveat is that the listing says every piece has IGI certification yet notes that the report is not included by default below 1ct.
- Best for
- A buyer who wants to choose both the cut and the size of a single lab diamond on an 18K chain.
- Skip if
- You want a stone above 1ct, a stated gold color or an IGI report on every size.
Why 3.3/5: With the IGI report optional on smaller sizes, a neutral point, the rating is pulled down by a thin spec sheet, made to order status and no independent buyer reviews found for the store.
The store sells this 18K gold necklace as a solitaire where you choose the shape: round, oval, pear, marquise, princess or emerald. Each version carries one lab diamond in a size from 0.25ct (4mm) to 1.00ct (6.5mm), listed as F or better for color and VS2 or better for clarity, on a 0.8mm chain. Prices run from $294.20 to $720.60 across the combinations.
Specifications

Options and pricing
Two options change the stone: Diamond shape (round, oval, pear, marquise, princess or emerald) and Diamond size (0.25ct, 0.50ct, 0.80ct or 1.00ct, which the listing gives as 4mm, 5mm, 6mm and 6.5mm). Prices run from $294.20 to $720.60, but the listing does not show which pairing costs what. The store shows a crossed-out higher price of $569.99 as well, a comparison it makes itself, not a market price.
How it compares
The 18K Gold Lab Diamond Solitaire Necklace lists From $99 with a title range of 0.1-3ct, against From $294.20 here for 0.25-1ct and a choice of six cuts. For pendants priced near this necklace's upper price of $720.60, the 2ct Oval Pink Diamond Pendant Only in 18K Rose Gold lists $718.50 and the 0.5ct Openwork Diamond Pendant in Platinum lists $724.20.
Shipping, returns and warranty
Shipping is free worldwide on most orders: made-to-order pieces need 10 to 18 business days before dispatch, then orders of $500 or more travel by DHL, FedEx, UPS or USPS in 3 to 7 business days. The FAQ says 10 to 18 business days when an IGI report is included plus 5 to 15 calendar days of delivery. Duties and taxes are included for most destinations. Returns: 30 days from delivery for eligible items, but custom orders and special orders (changes to an existing design) are final sale, and the page does not say whether an unmodified made-to-order design counts as returnable, so ask before paying; the buyer pays return shipping unless the item is wrong or defective, and an order can be cancelled only within three hours. Warranty: a free lifetime warranty, a one-time free replacement of a diamond up to 0.10 ct on first loss, and a promise to replace a diamond if the same grading laboratory later grades it lower. Checkout runs through PayPal, which also takes cards.
Before you buy
Rose Majester is a young store: its domain was registered in March 2025, and the company says it was founded in 2023 in Changsha, China, with a showroom in Macau. Searches on 19 October 2026 found no buyer reviews on Trustpilot, BBB or Reddit, so its claims have no outside check. Every listing we read shows a crossed-out higher price, and the store's "up to 76% lower than traditional retail" line is its own claim, not a market price. Its pages also disagree: delivery times differ between the shipping page and the FAQ, and the FAQ says every diamond piece over $500 comes with an IGI jewelry report while some listings call the report optional. Ask the store, for example on WhatsApp, to confirm the report, size and resizing before you pay, and keep the PayPal receipt.
What we liked
- Six cuts are offered in one listing: round, oval, pear, marquise, princess and emerald
- Color F or better and clarity VS2 or better are stated
- Stone sizes come with millimeter measurements, from 4mm to 6.5mm
- Chain length and thickness are given: adjustable 40cm plus a 5cm extender, 0.8mm
- The listing says pendants of 1ct or above come with an IGI certificate
Worth noting
- No gold color or metal line is given; 18K appears only in the title
- Below 1ct the IGI report costs $50 extra, and the listing says it is not the report for the center diamond
- Stone sizes stop at 1.00ct (6.5mm)
- The listing gives no price for each shape and size pairing within $294.20 to $720.60
Questions before you buy
Which diamond shapes can be chosen?
The Diamond shape option lists round, oval, pear, marquise, princess and emerald. Sizes are 0.25ct (4mm), 0.50ct (5mm), 0.80ct (6mm) and 1.00ct (6.5mm).
What does the listing say about the IGI report?
It says pendants of 1ct or above come with an IGI certificate, and that below 1ct the IGI report is not included by default, with an optional IGI Jewelry Report at +$50. Earlier it also says every piece is quality-assured with IGI certification, which does not match the later note.
What chain comes with the necklace?
It is adjustable at 40cm plus a 5cm extender, noted as 40cm-16inch and 45cm-18inch, and it is 0.8mm thick.
Can I return a made-to-order piece?
The refunds page gives a 30-day window for eligible items but lists custom orders and special orders (changes to an existing design) as final sale. It does not say whether an unmodified made-to-order design is returnable, so ask first. You pay return shipping unless the item is wrong or defective.
How long does a made-to-order piece take?
The shipping page says 10 to 18 business days before dispatch, then 3 to 7 business days in transit on orders of $500 or more; the FAQ says 10 to 18 business days when an IGI report is included, plus 5 to 15 calendar days of delivery. Shipping is free and duties are included for most destinations.
Does this piece come with an IGI report?
This listing says the IGI report is not included by default and offers an optional IGI Jewelry Report for an extra $50 and about three more business days. The store's FAQ says every diamond piece over $500 comes with one, so confirm before you pay.
Are lab-grown diamonds real diamonds?
GIA says laboratory-grown diamonds have the same crystal structure as natural diamonds, tightly bonded carbon atoms, and nearly the same chemical, optical and physical properties. By eye the difference can be indistinguishable, but gemological laboratories can detect the different growth history with advanced instruments. They are grown by high-pressure high-temperature (HPHT) or chemical vapor deposition (CVD).
