A pear is the only classic diamond shape with a direction. This loose one carat pear brilliant measures 8.63 x 5.60 x 3.47 mm — a 1.54 to 1 outline that tapers to a single point — and carries IGI report LG654448783 with a D color grade, VS 1 clarity, Excellent polish, and Excellent symmetry. Which way that point faces is the first decision you will make about it.

Which way the point faces
Round, oval, cushion, emerald: rotate any of them and nothing changes. A pear is different. One end is a rounded shoulder, the other narrows to a single point, and the convention is to wear that point outward, aiming toward the fingernail. Worn that way it pulls the eye down the length of the finger and keeps the widest part of the stone tucked toward the knuckle, where the hand is already broadest.
Turned the other way, point toward the wrist, the same diamond reads as an entirely different ring — less conventional, a little defiant, and a choice a fair number of people make deliberately. Neither is wrong. But it is a decision, and no other shape asks you to make it. Our guide to pear shaped engagement rings walks through both orientations and what each does on a hand.
Long, narrow, and quietly slimming
The measurements do the arguing here. At 8.63 mm along the long axis, this pear is about a third longer than the one carat round brilliant in the same collection is wide, and at 5.60 mm across it is nearly a millimeter narrower than that round. Longer along the finger, narrower across it — that combination is the whole reason a pear reads as slimming. The taper reinforces it: because the stone converges to a point rather than ending in a curve, the eye keeps travelling past the diamond instead of stopping at its edge.
The 1.54 to 1 ratio, calculated from the 8.63 x 5.60 mm outline, is at the longer end of the classic pear range, which is where the elongating effect is most pronounced. If that is the look you are after, it is worth seeing the shape mounted: our pear shaped engagement rings show how the outline behaves in a finished setting, and the rest of our loose gemstones are worth a look if you are planning a pairing.
Setting a point, and the settings that suit it
The point is the beautiful part and the vulnerable part. Diamond is Mohs 10 and will not scratch, but a sharp tip concentrates any impact into a very small area, so a competent setter protects it — usually with a V-prong that caps the tip, occasionally with a bezel that wraps it. This is not a reason to avoid the shape; it is one specification to give whoever mounts it.
Beyond that, a pear is unusually versatile. A plain solitaire lets the outline speak for itself. A halo widens the shoulder end and exaggerates the taper. Set east-west, or tilted on the diagonal, it becomes something you will not see on anyone else’s hand. Because this stone is sold loose, the design is genuinely open — our guide to building a custom engagement ring covers the process, and halo engagement rings are a good place to see the shoulder-and-taper effect at work.
Grades, growth, and what the report does not claim
D is the whitest grade on the D-to-Z scale: no detectable body color. VS 1 is very slightly included — found by a grader at 10x magnification, not seen by you across a table. Excellent polish means no visible finishing marks on the facet surfaces; Excellent symmetry means the facets meet where they should, which on a shape with a point is worth having. There is no cut grade on this report, because laboratories do not routinely assign one to fancy shapes, and we are not going to supply a number IGI did not.
The comments record that this diamond was created by the Chemical Vapor Deposition (CVD) growth process and classify it as Type IIa — the purest diamond type, containing essentially no nitrogen. It is a real diamond: same carbon lattice, same Mohs 10 hardness, same optics as a mined stone, and conflict-free because it was grown rather than extracted. If sourcing is part of why you are here, what makes jewelry ethical sets out how we think about it, and are lab grown diamonds worth it takes on the value question without the sales gloss.

Certification & care
The stone comes with IGI report LG654448783, issued September 28, 2024 by the International Gemological Institute, and the same number is laser inscribed on the girdle as “IGI LG654448783.” Enter the number into IGI’s online report verification service and the record should match your document; the inscription, readable under a loupe, ties that document to this particular diamond rather than to a lookalike. An independent appraisal can be arranged separately if you want a valuation for insurance.
Care starts with the point. At 8.63 x 5.60 x 3.47 mm the tip is the thinnest part of the stone, so store it in its own compartment or the gift box it arrives in rather than loose among other jewelry, and once it is set, take the ring off for anything involving impact. Cleaning is simple: warm water, a drop of mild soap, a soft brush around the setting, a rinse, and a lint-free cloth, as described in our guide to cleaning jewelry at home. Loose stones ship free within the USA, insured and tracked — see our shipping page for details, and our returns and refunds page for the loose-stone policy.
Frequently Asked Questions
What does IGI report LG654448783 cover?
It is the grading report for this specific diamond, issued September 28, 2024. It records the description as a laboratory grown diamond, the shape and cutting style as pear brilliant, measurements of 8.63 x 5.60 x 3.47 mm, a carat weight of 1.00, D color, VS 1 clarity, Excellent polish, Excellent symmetry, no fluorescence, the girdle inscription, and comments recording CVD growth and Type IIa classification.
Which way should a pear-shaped diamond be worn?
The usual convention is point outward, aiming toward the fingernail, which lengthens the look of the finger. Worn point-inward toward the wrist it reads as a deliberately unconventional choice, and plenty of people prefer it. There is no rule, only a decision — and the pear is the only classic shape that asks you to make one.
Why does a pear read as slimming on the finger?
Two reasons, both in the measurements. It is long: 8.63 mm along its axis, about a third longer than a one carat round is wide. And it is narrow: 5.60 mm across, nearly a millimeter narrower than that same round. Add the taper toward the point and the eye keeps moving past the stone rather than stopping at its edge.
Why does the report not list a cut grade?
Laboratories assign cut grades to round brilliants, where ideal proportions are standardized, and generally leave the line blank on fancy shapes such as pears. This report states no cut grade, so neither do we. Judge the cutting from the measured ratio, the depth, the Excellent polish and symmetry grades, and the photographs.
What is this pear's length-to-width ratio?
1.54 to 1, calculated by dividing the 8.63 mm length by the 5.60 mm width. That sits at the longer end of the classic pear range, which is where the elongating effect on the hand is most pronounced. Shorter pears, nearer 1.40, look fuller and rounder.
Does the point need special protection in a setting?
Yes, and it is a routine request. Diamond is Mohs 10 and will not scratch, but a sharp tip concentrates impact into a small area, so setters normally cap it with a V-prong or wrap it in a bezel. Ask for it explicitly when the stone is mounted.
What do D color and VS 1 clarity mean for this stone?
D is the top of the D-to-Z color scale: no detectable body color, so the diamond stays white against warm metals as well as cool ones. VS 1 means very slightly included — the inclusions are identifiable by a grader under 10x magnification and are not visible to the unaided eye in normal viewing.
Is a lab grown diamond a real diamond, and will it test as one?
Yes. It is crystallized carbon with the same lattice structure, the same Mohs 10 hardness, and the same optical properties as a mined diamond, so a standard diamond tester reads it as diamond. Telling grown from mined requires specialist laboratory equipment, which is what IGI used to produce this report.
What does Type IIa mean on the report?
Diamond type describes trace chemistry. Type IIa diamonds contain essentially no nitrogen, which is the purest category and relatively uncommon among mined stones. It is recorded in the comments section of this report alongside the CVD growth note.
How do I verify the report and find the laser inscription?
Enter LG654448783 into the International Gemological Institute's online report verification service and compare the record with the document you receive. The string IGI LG654448783 is laser inscribed on the girdle, invisible without magnification and irrelevant to the clarity grade, but decisive for identification under a loupe.
Can you set this pear into a ring for me?
Yes. The stone is sold loose and we take custom setting requests, so you choose the design, the metal, and the karat. The jeweler handles the setting work and the final band sizing, so the ring is built around the diamond and your finger together. Tell us which way you want the point to face.
Is this diamond conflict-free?
Yes. It was grown by the CVD process in a controlled chamber rather than extracted from the ground, so there is no mining supply chain behind it and its origin is documented from the start of growth.
How is it shipped, and what is the return policy on a loose stone?
It ships free within the USA, fully insured and tracked, packed with its IGI report and a luxury gift box. Loose stones follow the terms set out on our returns and refunds page, which are not identical to the terms for a finished ring, so please read them before ordering.
Can I have it appraised, and will it hold value?
An appraisal can be arranged and is genuinely useful for insurance. On resale value we will be blunt: lab grown diamonds are bought to be worn rather than traded, and prices in the category have moved downward as growing capacity has increased. The argument for this stone is that a D color, VS 1, one carat pear costs a fraction of the mined equivalent today, not that it will be worth more tomorrow.
