This one is solid gold throughout, hallmarked, and built around a certified stone. The marquise outline was chosen because it carries weight visually - at 1.0 carat it reads larger than a round stone of the same weight.

You set a budget, then discover that the natural stone at that price is half the size you pictured. The choice becomes compromise on the stone or stretch the budget, and neither feels good.\u003c\/p\u003e\u003ch2\u003eWhy Solid Gold Changes Everything\u003c\/h2\u003e\u003cp\u003eLab grown diamonds close that gap without asking you to accept a lesser stone. Identical hardness, identical brilliance, identical certification categories - a different origin and a different price. Combined with a solid gold setting, that means a bigger stone on a ring built to be worn every day. Every marquise lab diamond engagement ring we make is hallmarked and built to the same standard.\u003c\/p\u003e\u003ch2\u003ePicture This\u003c\/h2\u003e\u003cp\u003ePicture the moment you take it out. The stone catches the light before anything is said, and the size registers immediately - that is what a 1.0 carat centre stone does at arm's length. Years later it is still the ring being noticed, because solid gold does not wear thin and a diamond does not dull. A marquise lab diamond engagement ring is the piece people remember.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cp\u003eThe questions below are the ones buyers ask most often before choosing a marquise lab diamond engagement ring.\u003c\/p\u003e\u003ch3\u003eHow much is a 1 carat lab grown diamond engagement ring?\u003c\/h3\u003e\u003cp\u003eA 1 carat lab grown diamond engagement ring at Qutahia starts from around £1,100 in 9ct gold, £1,360 in 14ct and £1,575 in 18ct. Cut affects the price: emerald is the most affordable, marquise the highest. A natural diamond of the same weight typically costs three to five times more.\u003c\/p\u003e\u003ch3\u003eWhat is a marquise cut diamond?\u003c\/h3\u003e\u003cp\u003eA marquise is an elongated shape with pointed ends. It covers more finger than any other cut at the same carat weight, which is why it reads as the largest stone for the money.\u003c\/p\u003e\u003ch3\u003eWhich gold carat should I choose - 9ct, 14ct or 18ct?\u003c\/h3\u003e\u003cp\u003e9ct is the most common choice in the UK: it is harder, so it scratches less in daily wear, and it is the most affordable. 18ct gives a richer gold colour and is softer. 14ct sits between the two. All three are hallmarked.\u003c\/p\u003e\u003ch3\u003eAre lab grown diamonds certified?\u003c\/h3\u003e\u003cp\u003eIGI and GIA both certify lab grown diamonds. The certificate confirms carat, colour, clarity and cut, and states clearly that the stone is lab grown.\u003c\/p\u003e\u003ch3\u003eHow do I clean a lab grown diamond engagement ring?\u003c\/h3\u003e\u003cp\u003eWarm water, a few drops of washing-up liquid and a soft toothbrush are enough. Doing this once a month keeps the stone bright. Avoid chlorine and abrasive cleaners - the risk is to the gold setting rather than the stone.\u003c\/p\u003e\u003ch3\u003eLab grown diamond or moissanite - which is better?\u003c\/h3\u003e\u003cp\u003eMoissanite is not a diamond; it is silicon carbide. It throws more colour and costs less, but its hardness is 9.25. A lab grown diamond is harder at 10 and is certified as a diamond.\u003c\/p\u003e\u003ch3\u003eAre lab grown diamonds acceptable for an engagement ring?\u003c\/h3\u003e\u003cp\u003eA lab grown engagement ring is no longer a minority choice in the UK. It is a common decision among younger buyers, largely because the same budget buys a noticeably larger stone.\u003c\/p\u003e","brand":"Qutahia Jewellery","offers":[{"title":"Yellow Gold \/ 9 ct \/ LAB","offer_id":49658774356195,"sku":"101-10500-1-0-MQ-COL_YG-CT_9-LAB","price":1185.0,"currency_code":"GBP","in_stock":true},{"title":"Yellow Gold \/ 14 ct \/ LAB","offer_id":49658774388963,"sku":"101-10500-1-0-MQ-COL_YG-CT_14-LAB","price":1479.0,"currency_code":"GBP","in_stock":true},{"title":"Yellow Gold \/ 18 ct \/ LAB","offer_id":49658774421731,"sku":"101-10500-1-0-MQ-COL_YG-CT_18-LAB","price":1705.0,"currency_code":"GBP","in_stock":true},{"title":"White Gold \/ 9 ct \/ LAB","offer_id":49658774454499,"sku":"101-10500-1-0-MQ-COL_WG-CT_9-LAB","price":1185.0,"currency_code":"GBP","in_stock":true},{"title":"White Gold \/ 14 ct \/ LAB","offer_id":49658774487267,"sku":"101-10500-1-0-MQ-COL_WG-CT_14-LAB","price":1479.0,"currency_code":"GBP","in_stock":true},{"title":"White Gold \/ 18 ct \/ LAB","offer_id":49658774520035,"sku":"101-10500-1-0-MQ-COL_WG-CT_18-LAB","price":1705.0,"currency_code":"GBP","in_stock":true},{"title":"Rose Gold \/ 9 ct \/ LAB","offer_id":49658774552803,"sku":"101-10500-1-0-MQ-COL_RG-CT_9-LAB","price":1185.0,"currency_code":"GBP","in_stock":true},{"title":"Rose Gold \/ 14 ct \/ LAB","offer_id":49658774585571,"sku":"101-10500-1-0-MQ-COL_RG-CT_14-LAB","price":1479.0,"currency_code":"GBP","in_stock":true},{"title":"Rose Gold \/ 18 ct \/ LAB","offer_id":49658774618339,"sku":"101-10500-1-0-MQ-COL_RG-CT_18-LAB","price":1705.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/7180\/8995\/files\/large_3fd04bcd-d86e-45c5-a8d8-5feed24715a2.webp?v=1788324093","url":"https:\/\/qutahia.co.uk\/products\/marquise-lab-diamond-solitaire-engagement-ring-1-0ct-101-10500-1-0-mq","provider":"Qutahia Jewelry","version":"1.0","type":"link"}
