Our verdict
A straightforward round solitaire for a buyer who wants a 3.05ct stone in platinum with color, clarity and an IGI certificate stated, at $1,189.90. Look elsewhere if you need necklace length or a cut grade on the page. The main caveat is that grades are given only for the ready to ship stone, so made to order stones carry no grades in the listing.
- Best for
- A buyer who wants a four claw 3.05ct round lab diamond in platinum with an IGI certificate stated.
- Skip if
- You need a cut grade or a necklace length before choosing.
Why 3.6/5: An IGI certificate and ready to ship stock lift this listing; its short spec sheet and a new store with no independent buyer reviews found hold it back.
Four claws hold a 3.05ct round cut lab diamond on this Rose Majester platinum necklace. The ready to ship stone is graded E for color and VVS2 for clarity, and the listing says an IGI certificate comes with it. The price is $1,189.90, and the made to order choices cover 9K, 14K and 18K solid gold or platinum with stones from 0.25ct to 10ct.
Options and pricing
As listed ready to ship, the necklace is platinum with the 3.05ct stone and a 4 Claw style. Made to order, the store names 9K, 14K and 18K solid gold or platinum, with round cut lab diamonds from 0.25ct to 10ct. Only the price of $1,189.90 appears, with nothing on how other metals or sizes change it. A crossed-out higher price of $1,879 is also shown; that is the store's own comparison, not a market price.
How it compares
The closest match is the 3ct Round Diamond Classic Four-Prong V-Bail Pendant in Platinum, which lists a 3.07ct D, VVS2 stone at $1,059 against the 3.05ct E, VVS2 stone at $1,189.90 here. The 2ct Heart Solitaire Pendant Necklace in Platinum lists $1,164 for a heart shape, and the 2.5cttw Diamond Cross Pendant Necklace (11 Stones) in Platinum lists $1,257.
Shipping, returns and warranty
Shipping is free worldwide on most orders: ready-to-ship items are dispatched in 1 to 3 business days and orders of $500 or more travel by DHL, FedEx, UPS or USPS in 3 to 7 business days. The FAQ gives 8 to 12 business days of dispatch plus 5 to 15 calendar days instead, so allow for the longer figure. Duties and taxes are included for most destinations. Returns: 30 days from delivery for a refund of the product value and standard shipping, with the buyer paying return shipping unless the item is wrong or defective; custom orders, special orders, engraved items and altered loose diamonds are final sale, 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
- The ready to ship stone is listed at 3.05ct round cut with E color and VVS2 clarity.
- The listing says the necklace comes with an IGI certificate.
- A 4 Claw style is stated, along with platinum as the ready to ship metal.
- Made to order options span 9K to 18K solid gold and platinum, with stones from 0.25ct to 10ct.
Worth noting
- No chain length, chain type or pendant size is listed.
- The listing gives color and clarity but no cut grade.
- The certificate line does not say whether it covers made to order stones.
Questions before you buy
What is the ready to ship stone?
A 3.05ct round cut lab diamond graded E for color and VVS2 for clarity, in platinum with a 4 Claw style.
Which other metals can it be made in?
The made to order line lists 9K, 14K and 18K solid gold or platinum, with round cut lab diamonds from 0.25ct to 10ct.
What does the listing say about a certificate?
It says the necklace comes with an IGI certificate, in a single line that does not name the version it covers.
Can I return it if I change my mind?
The refunds page gives 30 days from delivery for eligible items and refunds the product value and standard shipping; you pay return shipping unless the item is wrong or defective. Custom orders, special orders, engraved items and altered or tested loose diamonds cannot be returned, and cancellation is possible only within three hours.
How long until it arrives?
The shipping page says ready-to-ship items are dispatched in 1 to 3 business days and arrive in 3 to 7 business days on orders of $500 or more (8 to 25 business days by postal service under $500); the FAQ says 8 to 12 business days of dispatch plus 5 to 15 calendar days. Shipping is free and duties are included for most destinations.
Is an IGI report included?
The store's FAQ says every diamond jewelry piece over $500 comes with an IGI Laboratory Grown Diamond Jewelry Report, which certifies the finished piece rather than only the center stone. Check this listing's text and ask the store to 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).
