A 2.0ct lab-grown pink diamond heart pendant from Carat Club Co. costs HK$17,000. That figure does not move with your choice: Fancy Pink, Fancy Intense Pink and Fancy Vivid Pink are all HK$17,000, in 18K White Gold, 18K Rose Gold or PT950 Platinum. What you are choosing is how the piece looks, not how much it costs.
What does a pink diamond heart pendant actually cost?
The piece behind that number is the Sweetheart Pink Diamond Pendant: a 2.0ct heart-shaped lab-grown pink diamond, VS1 to VVS2 clarity, Excellent cut, held in a three-prong setting over an open gallery base so the back of the stone is not closed off. It hangs on a fine link chain that adjusts between 40cm and 45cm with a lobster clasp.
Natural pink diamonds at this size trade in an entirely different market, and that is the whole reason a 2.0ct pink heart can sit at this price at all. Lab-grown is what puts the stone within reach.
Sweetheart Pink Diamond Pendant
The 2.0ct pink heart itself, individually IGI-certified, offered in three saturations at one price.

View productWhy isn't the pink graded like a colourless diamond?
Most people arrive knowing the D-to-Z scale and try to apply it. It does not fit. As GIA explains, the D-to-Z system measures the relative absence of colour, while fancy colour grading measures its presence. A fancy colour diamond is described by hue (the colour itself, in this case pink), tone (how light or dark it is) and saturation (how intense it is). The hue is then modified by a Fancy-grade term that captures the combined effect of tone and saturation.
That is why the Sweetheart is sold as Fancy Pink, Fancy Intense Pink or Fancy Vivid Pink rather than as a letter. Asking whether a pink diamond is D colour is like asking how loud a photograph is. Wrong instrument.
Which pink intensity should you choose?
All three cost HK$17,000, so this is purely a question of what you want to see on the neck.
- Fancy Vivid Pink reads as colour first. It announces itself across a room, and people register the pink before they register the heart shape.
- Fancy Pink reads as a blush. In some light it looks almost neutral, in others it clearly turns pink. Easier to wear on an ordinary Tuesday.
- Fancy Intense Pink sits between the two: unmistakably pink in normal indoor light, without dominating everything else you are wearing.
None of these is better or rarer than another at Carat Club Co., and none costs more. If the pendant is a gift for someone who wears very little jewellery, the quieter end tends to get worn more. If it is meant to be the one thing they wear, go up.
One practical note on how the order works: you pick your saturation by messaging Carat Club Co. on WhatsApp after ordering. Ask everything you want to ask before you place the order, because each piece is made to order and there are no returns.
Which metal suits a pink stone?
Rose gold warms the stone and amplifies it. The pink of the metal and the pink of the diamond run together, so the pendant reads as one continuous colour and feels softer overall. White gold and platinum do the opposite. They stay cool, and the pink sits against them as a contrast, which sharpens the stone and makes the colour look more deliberate.
Neither approach is more expensive here, which is worth pausing on, because metal normally does move the price. If you want to understand where that difference usually comes from, we broke down how much the metal adds to the price in a separate piece.
What does the certificate cover?
IGI does the grading. Carat Club Co. includes the certificate. In the certified lines, centre stones of 0.5ct and above carry an individual IGI certificate, and the 2.0ct heart in the Sweetheart is individually IGI-certified.
A certificate is only useful if you check it, and checking takes about a minute on IGI's own site. Here is how to verify an IGI certificate yourself, whoever you end up buying from.
What if you want a pendant but not a pink one?
Worth saying plainly: the Sweetheart is the only fancy colour piece Carat Club Co. makes. There is no menu of blues, yellows and greens behind it. If pink is not the point and the pendant is, the Rhapsody covers the same brief in colourless stones, with five graduating round brilliants falling in a vertical line rather than a single centre stone.
It starts at HK$20,000 and is built around a focal stone of 0.30ct, 0.50ct, 0.70ct, 1.0ct or 2.0ct, D colour, VVS2 clarity, in 18K White Gold or PT950 Platinum on a substantial 3g solid chain. In the smaller configurations, the graduating stones under 0.5ct are not separately certified, because independent grading costs more than those stones do. Certification for them is available on request.
Rhapsody 5-Stone Diamond Pendant Necklace
The colourless alternative, with five graduating stones and a focal stone from 0.30ct to 2.0ct.

View productIs there a cheaper way in?
If HK$17,000 is above where you want to be, there are two honest options, and neither is a smaller pink diamond.
The Token of Love bracelet at HK$6,000 has pink in it, but the pink is the cord, not the stone. The diamond is a 1ct colourless round brilliant, D colour, VVS2 clarity, individually IGI-certified, bezel-set on a woven cord with a fine metal chain. The cord comes in Signature Red, Soft Pink or Classic Black, the closure adjusts across 15cm, 16cm and 17cm wrists, and up to three initials can be monogrammed on the clasp plate at no charge. If someone wants pink as a colour story rather than pink as a stone, this does that job for a third of the price.
Token of Love Diamond Cord Bracelet
Pink as a cord colour, not a stone colour, with a 1ct colourless diamond and a free three-initial monogram.

View productThe second option is to drop the format entirely. The Essential studs start at HK$2,300 for a single 0.5ct round brilliant in 9K White Gold, individually certified by IGI. It is a useful reference point for what a certified stone costs when the budget is a fraction of a pink heart's.
Essential Diamond Solitaire Studs
The entry reference point: a certified 0.5ct stone at a fraction of the pendant budget.

The Sweetheart chain adjusts between 40cm and 45cm. At the short end the pendant sits close to the base of the neck, at the long end it drops onto the chest and clears a crew neckline, so the same necklace works over a shirt and under one.
Everything is made to order in two to three weeks. There is a one-year free repair covering workmanship, and a seven-day exchange if a piece arrives defective. There are no returns, which is exactly why the WhatsApp conversation about saturation is worth having before you pay rather than after. Carat Club Co. ships to Hong Kong and 14 other Asian markets. Delivery is free in Hong Kong, and free internationally on orders of HK$9,000 and above, so a HK$17,000 pendant ships without a delivery charge. Hong Kong orders travel with SF Express under paid declared-value protection, and international orders carry declared-value cover to the maximum the carrier permits for fine jewellery.
